Indigestion, also called dyspepsia, is the term used to describe one or more symptoms including burning or pain in the area of the upper abdomen, feeling of fullness during a meal, and uncomfortable fullness after a meal. In some people, the condition can occur once in a while. While in others, indigestion may occur as often as every day.

There are many indigestion causes including gastroesophageal reflux disease (GERD), peptic ulcers, cancer, or abnormality of the pancreas or bile ducts. If the condition improves or resolves, indigestion symptoms usually improve.

Sometimes, the cause of indigestion cannot be found. This indigestion type is called functional dyspepsia, which is thought to occur in the area where the stomach meets with the small intestine. The indigestion may be related to abnormal motility—the squeezing or relaxing action—of the stomach muscle as it receives, digests, and moves food into the small intestine.

Indigestion Symptoms

People with dyspepsia or indigestion usually have more than one of the following symptoms:

 Fullness during a meal. The person feels overly full soon after the meal starts and cannot finish the meal.

 Bothersome fullness after a meal. The person feels overly full after a meal—it may feel like the food is staying in the stomach too long.

 Epigastric pain. The epigastric area is between the lower end of the chest bone and the navel. The person may experience epigastric pain ranging from mild to severe.

 Epigastric burning. The person feels an unpleasant sensation of heat in the epigastric area.
Some rare symptoms of the condition include nausea and bloating—the sensation of unpleasant tightness in the stomach. However, nausea and bloating may be caused by digestive problems other than indigestion.

Indigestion Treatment

In some people, making some lifestyle changes and decreasing stress may help relieve the symptoms of indigestion. Lifestyle changes may include eating several small; low fat meals throughout the day at a slow pace; quitting smoking; avoiding coffee, carbonated drinks, and alcohol; and stopping medications that may irritate the lining of the stomach, such as aspirin or anti-inflammatory drugs.

Your doctor may recommend over-the-counter antacids or medications, which help reduce acid production in the stomach. Medicines that help the stomach move food more quickly into the small intestine may also help.

Some medications that your doctor might prescribe may include antacids, H2 receptor antagonists (H2RAs), proton pump inhibitors (PPIs), prokinetics, or antibiotics to treat the symptoms of indigestion.

Peptic ulcers are sores that form in the inner lining of the stomach and sometimes in the duodenum. The duodenum is the first part of the small intestine. Peptic ulcer names may be different depending on the digestive tract involved. When it occurs in the stomach, it is called gastric ulcer. A peptic ulcer occurring in the duodenum is called duodenal ulcer.

Many people have peptic ulcer. It can occur both in the stomach and duodenum. Sometimes, you can have more than one ulcer in your lifetime.

Peptic Ulcer Causes

Peptic ulcer is commonly caused by the bacteria called H. pylori. Experts believe that H. pylori may be spread through eating and drinking contaminated food and water. Also, the bacteria may be spread through kissing.

The second leading cause of peptic ulcer is long-term use of pain-reliever drugs, called NSAIDs. According to the National Digestive Diseases Information Clearinghouse (NDDIC), ulcers caused by NSAIDs are more often found in people who are age 60 or older; are female; have taken NSAIDs for a long time; and have had ulcer before.

Contrary to the notion, stress and eating spicy foods do not cause peptic ulcers. However, they can make ulcers worse and can affect healing.

Peptic Ulcer Symptoms

Peptic ulcer symptoms may include weight loss, poor appetite, bloating, burping, vomiting, and feeling sick to your stomach. However, the most common symptom of peptic ulcer is dull or burning pain in the stomach. The pain often starts between meals or during the night, briefly stops if you eat or take antacids, lasts for minutes to hours, comes and goes for several days or weeks.

Peptic Ulcers Treatment

Peptic ulcer treatment may include medicines to reduce stomach acid and protect the lining of your stomach and duodenum; antibiotics to kill the bacteria H. pylori; and medicines to coat the ulcer and protect them from stomach acid.

If NSAIDs use is the primary cause of peptic ulcer, your doctor may tell you to stop taking them or reduce how much of the NSAID you take. Your doctor may also prescribe an alternative pain medication that does not cause peptic ulcer.

Avoid smoking and drinking alcohol. Smoking and alcohol can make slow healing of ulcers and can make them worse.

Diarrhea occurs when a person has a change in bowel movements, passing unusually loose and watery stools. For most cases, the condition usually goes away without special medical treatment. However, diarrhea can be potentially life-threatening if it leads to dehydration.

Causes

Diarrhea can be caused by microorganisms, such as bacteria, viruses, or parasites. Other causes of diarrhea include certain medications, certain food like milk, or health problems affecting the stomach or the intestines.

Normally, stool has a semi-solid consistency. The stool is the one that’s left when most of food molecules including vitamins and minerals and water, needed by the body, are absorbed. As stool passes through the large intestine, some of its water content is absorbed making stool a little bit solid. However, when water is not absorbed, the stool can become loose and watery.

Symptoms of Diarrhea

People with diarrhea often have unusual frequent bowel movements, which results in passing more than a quart of watery stool per day. It is a common condition, which usually lasts a day or two. Sometimes, the condition can last for months or years depending on the cause.

Other symptoms of diarrhea may include cramping in the abdomen, frequent urge or need to have a bowel movement, uncomfortable feeling in the anus, and sometimes fever or chills.

Sometimes severe diarrhea can lead to dehydration where water and important body salts are lost. In dehydration, the body cannot work properly, which can make a person become or feeling tired. Dehydration is a serious complication of diarrhea, especially in babies, children, and older people.

Symptoms of Dehydration

Symptoms of dehydration include being thirsty, urinating less often than usual, having dark-colored urine, having dry skin, feeling tired or dizzy, and fainting. In more severe cases, diarrhea may cause kidney failure where the kidneys stop to function.

It may be difficult to know when babies are experiencing dehydration. Symptoms of dehydration in babies may include having dry mouth and tongue, crying without tears, having no wet diapers for 3 hours or more, having a high fever, and being unusually sleepy or drowsy. These warning signs of diarrhea that needs special medical attention.

Diarrhea symptoms may be signs of other problems in the digestive tract as well.

Treatments

Treatment of diarrhea usually involves replacing the lost fluids. However, severe diarrhea cases may need hospitalization. In some cases, treating the cause can make diarrhea go away. For example, diarrhea caused by bacteria can be effectively treated with antibiotics.

The digestive system is composed of the digestive tract and organs that aid in digestion of food. The digestive tract includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and the anus.

Other organs or structures that help in digesting food are the teeth, salivary glands, the liver, and the pancreas.

The following are brief descriptions of the common digestive diseases.

Appendicitis

Appendicitis is the inflammation of the appendix—a small organ attached to the first part of the large intestine. It can be caused by blockage to the lumen of the appendix.

Illustration of the digestive tract.The bacteria in the appendix can multiply and cause inflammation of the appendix. Symptoms of disease include pain in the lower right part of the abdomen, low-grade fever, nausea and vomiting.


Colon and Rectal Cancer

Cancer of the colon and rectum is sometimes called colorectal cancer. A type of cancer, colorectal cancer is one of the leading causes of cancer-related deaths worldwide, according to recent data provided by the World Health Organization. The condition occurs when cells in the colon or rectum abnormally divide forming a mass called tumor. The cancer cells can travel through the blood or lymph causing cancer in other organs of the body.

Possible signs of colon or rectal cancer include change in bowel habits and blood in the stool.

Colorectal cancer treatment is more effective if found early where cancer has not spread to other parts of the body. Treatment options for colorectal cancer include surgery, chemotherapy, and radiation therapy or a combination of these treatments.

Diarrhea

Diarrhea is a common problem, which is described as having loose, watery stools. People with diarrhea, according to the National Digestive Diseases Information Clearinghouse (NDDIC), often have frequent bowel movements and may pass more than a quart of watery stool a day. Having diarrhea can cause a person to be dehydrated, which can be life-threatening.

Common causes of diarrhea include infection with bacteria, viruses, or parasites; some foods; or health problems affecting the digestive system.

The main treatment of diarrhea involves replacing lost fluids.

Foodborne Illness or Food Poisoning

Foodborne illness can be caused by foods and beverages that have been contaminated by bacteria, viruses, or parasites. Symptoms of foodborne illness include upset stomach, diarrhea, abdominal cramping, and vomiting.

Gas (Flatulence)

Everyone can have gas, may it be in the form of burping or passing gas. More often, gas is odorless. The odor in passed gas, however, can be caused by sulfur that is normally produced by bacteria in the colon. Limiting foods known to cause gas may help.

Gastritis

Gastritis is the inflammation of the lining of the stomach. It is not a single disease but actually several conditions that have some inflammation of the stomach lining. Too much alcohol drinking, long-term use of certain pain relievers and certain bacterial infection can cause gastritis. Other health problems or conditions can cause gastritis as well.

Gastritis symptoms include pain or abdominal upset, bloating, and burning in the upper abdomen.

Gastroesophageal reflux (GER)

Gastroesophageal reflux occurs when the muscle called lower esophageal sphincter (LES) fails to close allowing stomach acid to flow back into the esophagus. The LES is a smooth muscle that acts as a valve between the esophagus and the stomach. The flowing back of stomach contents including acid is called a reflux, which can cause heartburn—a burning sensation on the chest.

Gastroesophageal reflux disease (GERD)

Gastroesophageal reflux disease is the more serious form of gastroesophageal reflux (GER). A reflux that occurs more often may mean that a person has GERD. Like GER, heartburn is a common symptom of GERD. However, GERD that persists for a long time can lead to more serious problems in the digestive tract.

Hemorrhoids

Hemorrhoids are swollen, inflamed veins around the anus or lower rectum. It is common in both men and women. In fact, according to the National Digestive Diseases Information Clearinghouse, about half of the population will experience hemorrhoids by age 50. The most common symptom of hemorrhoids is having blood in the stool. Pain may also be felt around the anus.

Most cases of hemorrhoids are temporary and usually goes away without special medical treatment.

Heartburn

Heartburn is the burning sensation felt on the chest when acid in the stomach flows back in the esophagus—the tube connecting the pharynx to the stomach. Heartburn is more of a symptom of a health problem rather than a disease itself.

Stomach Ulcers (Peptic Ulcers)

A stomach ulcer is a type of peptic ulcer that occurs when a sore develops in the lining of the stomach. Sometimes peptic ulcer occur in the duodenum—the first part of the small intestine—called duodenal ulcer. Most cases of stomach ulcers are caused by bacteria called Helicobacter Pylori or H. pylori. Long term use of certain pain relievers can cause the condition as well. Symptoms of stomach ulcer include gnawing abdominal pain, poor appetite, weight loss, nausea and vomiting.

Having difficulty of passing stool? Or maybe you have stool that is dry, hard, and painful passing of stool? If your answer to this is yes, you are probably experiencing constipation.

Fact is, constipation is one of the leading gastrointestinal complaints in the United States. According to the National Institute of Diabetes and Digestive and Kidney Diseases, more than 4 million Americans have frequent constipation, accounting for 2.5 million physician visits a year.

Constipation, according to the National Institute of Digestive Diseases Information Clearinghouse (NDDIC), is defined as having a bowel movement fewer than three times per week. A person with constipation usually has stools that are dry, hard, small in size, and difficult to pass.

What causes constipation?

Common causes of constipation are:

  • Not eating enough fibers
  • Physical inactivity (especially in the elderly)
  • Ignoring the urge to have a bowel movement
  • Certain medications, and
  • Dehydration

Sometimes, constipation may be caused by other health problems or conditions, such as stroke, irritable bowel syndrome (IBS), problems in the colon, and even pregnancy. Abuse of laxatives may also cause the condition.

Normally, some of the water contents of stool are absorbed by the large intestine or the colon. However, constipation occurs when the colon absorbs too much water or the colon’s muscle contraction is too slow, which causes the stool to move very slowly. This can cause stools to become hard and dry.

What are the available treatments for constipation?

Most cases of constipation last for only a short time and usually is not serious. Sometimes, treating the underlying cause can make the constipation go away. Laxatives are not advisable for everyone. The doctor may recommend laxative for cases where constipation that do not improve. However, laxatives are recommended for a limited time only.

To prevent constipation, experts recommend eating foods high in fiber, drinking enough fluids, visiting the restroom when the urge to have a bowel movement is felt, and exercising regularly.

Hemorrhoids, also called piles, can sometimes be painful or irritating and may cause alarm to an individual. Hemorrhoids, according to the National Library of Medicine, are swollen, inflamed veins around the anus or lower rectum. It can result from too much straining during bowel movement. Other factors such as pregnancy, aging, chronic constipation or diarrhea, and anal intercourse can contribute to the development of hemorrhoids.

Hemorrhoids are very common and can occur in both men and women. In fact, according to the National Institute of Diabetes and Digestive and Kidney Diseases, about half of all people will experience hemorrhoids by age 50.

The two types of hemorrhoids are internal hemorrhoids and external hemorrhoids. When hemorrhoids occur inside the anus, it is called internal hemorrhoids. When it occurs under the skin around the anus, this is called external hemorrhoids.

Symptoms of Hemorrhoids

Some people do not experience symptoms of hemorrhoids. However, some people with internal bleeding hemorrhoids may notice some bright red blood covering their stool, on toilet paper, or in the toilet bowl. In some cases, an internal hemorrhoid may protrude through the anus outside the body, which can become irritated and cause pain. This condition is called protruding hemorrhoid.

In external hemorrhoids, symptoms may include painful swelling or a hard lump around the anus, which can result from the formation of a blood clot. This is known as a thrombosed external hemorrhoid.

Hemorrhoids are Common in Pregnant Women

According to the National Institute of Diabetes and Digestive and Kidney Diseases, hemorrhoids are common among pregnant women. However, this is usually a temporary problem. The presence of the growing fetus on the abdomen, as well as hormonal changes, cause the hemorrhoidal vessels to enlarge. These vessels can also be placed under severe pressure during labor or childbirth.

Diagnosis of Hemorrhoids

In most cases, hemorrhoids are not dangerous or life threatening. However, it is recommended that a thorough evaluation and proper diagnosis is done whenever bleeding in the rectum or blood in the stool occurs. Bleeding can be caused by other disorders of the digestive system, including colon or rectal cancer.

In addition to learning about your symptoms and family and medical history, your doctor will also perform a thorough physical exam. Your doctor may also use medical gadgets, such as an anoscope or proctoscope to view the inside of your rectum.

Your doctor may also recommend viewing your lower colon or sigmoid using a sigmoidoscope or your entire colon with the use of a colonoscope. Sigmoidoscopy and colonoscopy are diagnostic procedures that can help your doctor see the inside of your large intestine, including the rectum and anus.

Treatment of Hemorrhoids

Medical treatment of hemorrhoids is aimed initially at relieving symptoms. Measures to reduce symptoms include

 tub baths several times a day in plain, warm water for about 10 minutes

 application of a hemorrhoidal cream or suppository to the affected area for a limited time
Preventing the recurrence of hemorrhoids will require relieving the pressure and straining of constipation.

Fiber and Fluid Intake
Your doctor may recommend that you increase fiber and fluid intake in your diet. Eating the right amount of fiber and drinking six to eight glasses of fluid result in softer, bulkier stools. A softer stool makes emptying the bowels easier and lessens the pressure on hemorrhoids caused by straining. Eliminating straining also helps prevent the hemorrhoids from protruding.

Good sources of fiber are fruits, vegetables, and whole grains. Avoid drinking alcohol, as this tends to make you eliminate more fluid through urination.

In some cases, hemorrhoids must be treated endoscopically or surgically. These methods are used to shrink and destroy the hemorrhoidal tissue. The doctor will perform the procedure during an office or hospital visit.

Medical Procedures
A number of methods may be used to remove or reduce the size of internal hemorrhoids. These techniques include
 Rubber band ligation. A rubber band is placed around the base of the hemorrhoid inside the rectum. The band cuts off circulation, and the hemorrhoid withers away within a few days.

 Sclerotherapy. A chemical solution is injected around the blood vessel to shrink the hemorrhoid.

 Infrared coagulation. A special device is used to burn hemorrhoidal tissue.

 Hemorrhoidectomy. Occasionally, extensive or severe internal or external hemorrhoids may require removal by surgery known as hemorrhoidectomy.(National Institute of Diabetes and Digestive and Kidney Diseases, 2004)

Gastritis is the inflammation of the inner lining of the stomach. This is not a single disease, but rather, several disorders that all have inflammation of the stomach lining. Gastritis may be acute or chronic. Acute gastritis occurs suddenly while chronic (long-term) gastritis can occur over a long period of time.

Causes of Gastritis

Gastritis can be caused by

 excessive alcohol drinking

 lon-term use of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Examples of NSAIDs include aspirin and ibuprofen.

 infection with bacteria such as Helicobacter pylori (H. pylori)—the same bacteria that causes peptic ulcers.

 degeneration of the stomach lining due to advanced age.
In some cases, gastritis develops after a major surgery, burns, severe infections, or traumatic injury. Other health problems, such as autoimmune disorders, pernicious anemia, and chronic bile reflux, can also cause gastritis to develop.

Signs and Symptoms of Gastritis

The most common symptom is abdominal upset or pain. Other symptoms may also include
 belching

 abdominal bloating

 nausea

 vomiting

 feeling of fullness

 burning sensation in the upper abdomen
When you notice blood in your vomit or have black stools, it may be a sign of bleeding in the stomach, which can be serious. Seek immediate medical attention.

Diagnosis

Gastritis is diagnosed through one or more medical tests:
 Upper gastrointestinal endoscopy.

Your doctor eases an endoscope, a thin tube containing a tiny camera, through your mouth (or occasionally nose) and down into your stomach to look at your stomach lining. He or she will check for inflammation and may remove a tiny sample of stomach tissue for tests. This procedure to remove a tissue sample is called a biopsy.

 Blood test.

The doctor may check your red blood cell count to see whether you have anemia, which means that you do not have enough red blood cells in your blood. Bleeding from the stomach can cause anemia.

 Stool test.

This test checks for the presence of blood in your stool, a sign of bleeding. Stool test may also be used to detect the presence of H. pylori in the digestive tract.
Treatment of Gastritis

Treatment of gastritis depends on the cause. In some cases, once the underlying cause disappears, the gastritis usually does too.

Your doctor may prescribe antacids or medications that reduce or neutralize stomach acid, which help relieve symptoms and promote healing. Stomach acid can irritate the inflamed tissue in the stomach. Your doctor may also recommend that you avoid certain foods, beverages, or medications that cause gastritis.

If your gastritis is caused by an infection, that problem may be treated as well. For example, your doctor might prescribe antibiotics to clear up H. pylori infection. Talk to your doctor before stopping any medicine or starting any gastritis treatment on your own.

An inguinal hernia occurs when intra-abdominal fat or part of the small intestine bulges through a weak spot in the lower abdominal muscles. An inguinal hernia occurs in the groin—the area between the abdomen and thigh.

Inguinal hernia occurs more commonly in males than females and can occur any time from infancy to adulthood.

Types

There are two types of inguinal hernia: direct hernia and indirect hernia. These two types have different causes.

Indirect Inguinal Hernia

Indirect inguinal hernias are congenital hernias and are much more common in males than females because of the way males develop in the womb.

Inguinal HerniaIn a male fetus, the spermatic cord and both testicles—starting from an intra-abdominal location—normally descend through the inguinal canal into the scrotum, the sac that holds the testicles. Sometimes the entrance of the inguinal canal at the inguinal ring does not close as it should just after birth, leaving a weakness in the abdominal wall. Fat or part of the small intestine slides through the weakness into the inguinal canal, causing a hernia.

In females, an indirect inguinal hernia is caused by the female organs or the small intestine sliding into the groin through a weakness in the abdominal wall.

Indirect hernias are the most common type of inguinal hernia. Premature infants are especially at risk for indirect inguinal hernias because there is less time for the inguinal canal to close.

Direct inguinal hernia

Direct inguinal hernias are caused by connective tissue degeneration of the abdominal muscles, which causes weakening of the muscles during the adult years. Direct inguinal hernias occur only in males. The hernia involves fat or the small intestine sliding through the weak muscles into the groin. A direct hernia develops gradually because of continuous stress on the muscles. One or more of the following factors can cause pressure on the abdominal muscles and may worsen the hernia:

 sudden twists, pulls, or muscle strains

 lifting heavy objects

 straining on the toilet because of constipation

 weight gain

 chronic coughing
Indirect and direct inguinal hernias usually slide back and forth spontaneously through the inguinal canal and can often be moved back into the abdomen with gentle massage.

Symptoms

Symptoms of an inguinal hernia usually appear gradually and include a bulge in the groin, discomfort or sharp pain, a feeling of weakness or pressure in the groin, and a burning, gurgling, or aching feeling at the bulge.

Incarcerated and Strangulated Inguinal Hernias

An incarcerated inguinal hernia is a hernia that becomes stuck in the groin or scrotum and cannot be massaged back into the abdomen.

A strangulated hernia, in which the blood supply to the incarcerated small intestine is jeopardized. This condition is serious, which requires immediate medical care. Symptoms include extreme tenderness and redness in the area of the bulge, sudden pain that worsens quickly, fever, rapid heart rate, nausea, and vomiting.

Diagnosis of Inguinal Hernia

To diagnose inguinal hernia, the doctor takes a thorough medical history and conducts a physical examination. The person may be asked to stand and cough so the doctor can feel the hernia as it moves into the groin or scrotum. The doctor checks to see if the hernia can be gently massaged back into its proper position in the abdomen.

Treatment of Inguinal Hernia

Inguinal hernias may be repaired through surgery. Surgery is performed through one incision or with a laparoscope and several small incisions.

Surgery for inguinal hernia is usually done on an outpatient basis. Recovery time varies depending on the size of the hernia, the technique used, and the age and health of the patient.

Complications

Complications from inguinal hernia surgery are rare and can include general anesthesia complications, hernia recurrence, bleeding, wound infection, painful scar, and injury to internal organs.

The stomach is a j-shaped, hollow, distensible organ located in the upper left corner of the abdomen. The stomach has several digestive glands, which produce stomach acid and enzyme that digest protein.

Common Stomach Diseases or Disorders

Illustration of the digestive tract, showing the location of the stomach.Cyclic Vomiting Syndrome (CVS)

CVS is characterized by episodes or cycles of severe nausea and vomiting that last for hours, or even days, that alternate with intervals with no symptoms. Although originally thought to be a pediatric disease, CVS occurs in all age groups. Medical researchers believe CVS and migraine headaches are related.

Many people can identify a specific condition or event that triggered an episode, such as an infection. Common triggers in children include emotional stress and excitement. Anxiety and panic attacks are more common triggers in adults. Colds, allergies, sinus problems, and the flu can also set off episodes in some people.
Other reported triggers include eating certain foods such as chocolate or cheese, eating too much, or eating just before going to bed. Hot weather, physical exhaustion, menstruation, and motion sickness can also trigger episodes.

Gastroparesis

Gastroparesis, is a disorder in which the stomach takes too long to empty its contents. It is also known as delayed gastric emptying. Normally, the stomach contracts to move food down into the small intestine for digestion. The vagus nerve controls the movement of food from the stomach through the digestive tract. Gastroparesis occurs when the vagus nerve is damaged and the muscles of the stomach and intestines do not work normally. Food then moves slowly or stops moving through the digestive tract.

Gastroparesis may occur in people with type 1 diabetes or type 2 diabetes. The vagus nerve becomes damaged after years of high blood glucose, resulting in gastroparesis. In turn, gastroparesis contributes to poor blood glucose control.

Symptoms of gastroparesis include early fullness, abdominal pain, stomach spasms, heartburn, nausea, vomiting, bloating, gastroesophageal reflux, lack of appetite, and weight loss.

Gastritis

Gastritis is not a single disease, but several different conditions that all have inflammation of the stomach lining. Gastritis can be caused by drinking too much alcohol, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen, or infection with bacteria such as Helicobacter pylori (H. pylori). Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections. Certain diseases, such as pernicious anemia, autoimmune disorders, and chronic bile reflux, can cause gastritis as well.

The most common symptoms are abdominal upset or pain. Other symptoms are belching, abdominal bloating, nausea, and vomiting or a feeling of fullness or of burning in the upper abdomen. Blood in your vomit or black stools may be a sign of bleeding in the stomach, which may indicate a serious problem requiring immediate medical attention.


Peptic Ulcers

A peptic ulcer is a sore on the lining of the stomach or duodenum, which is the beginning of the small intestine. Peptic ulcers are common: One in 10 Americans develops an ulcer at some time in his or her life. One cause of peptic ulcer is bacterial infection, but some ulcers are caused by long-term use of nonsteroidal anti-inflammatory agents (NSAIDs), like aspirin and ibuprofen. In a few cases, cancerous tumors in the stomach or pancreas can cause ulcers. Peptic ulcers are not caused by stress or eating spicy food, but these can make ulcers worse.

The most common symptom of peptic ulcer is abdominal discomfort. Other symptoms may include weight loss, poor appetite, bloating, burping, nausea, and vomiting. Some people experience only very mild symptoms or none at all.

Indigestion

Indigestion, also known as dyspepsia, is a term used to describe one or more symptoms including a feeling of fullness during a meal, uncomfortable fullness after a meal, and burning or pain in the upper abdomen.

Most people with indigestion experience more than one of the following symptoms:
 The person feels overly full soon after the meal starts and cannot finish the meal.
 The person feels overly full after a meal—it may feel like the food is staying in the stomach too long.

 The epigastric area is between the lower end of the chest bone and the navel. The person may experience epigastric pain ranging from mild to severe.

 The person feels an unpleasant sensation of heat in the epigastric area.
Other, less frequent symptoms that may occur with indigestion are nausea and bloating—an unpleasant tightness in the stomach. Nausea and bloating could be due to causes other than indigestion.

Rapid Gastric Emptying

Rapid gastric emptying, also called dumping syndrome, occurs when undigested food empties too quickly into the small intestine.

Early rapid gastric emptying begins either during or right after a meal. Symptoms include nausea, vomiting, bloating, cramping, diarrhea, dizziness, and fatigue. Late rapid gastric emptying occurs 1 to 3 hours after eating. Symptoms include hypoglycemia, also called low blood sugar; weakness; sweating; and dizziness. Experiencing both forms of gastric emptying is not uncommon.

Rare Stomach Disorder

Zollinger-Ellison syndrome (ZES)

ZES is a rare disorder characterized by one or more tumors in the pancreas, duodenum, or both. The tumors cause the stomach to make too much acid, leading to peptic ulcers in the duodenum. The tumors are sometimes cancerous and spread to other areas of the body.

Symptoms of Zollinger-Ellison Syndrome are similar to those of peptic ulcers and include burning abdominal pain, nausea and vomiting, weight loss, diarrhea, severe gastroesophageal reflux—a condition where gastric acid and food from the stomach backs up into the esophagus.

The Inflamed Appendix

Appendicitis is the medical term for the inflammation of the appendix. The appendix is a fingerlike pouch attached to the first part of the large intestine called cecum. It is located in the lower right area of the abdomen.

Although anyone can get appendicitis, it is more common among people aged 10 to 30 years old.

Experts are not sure what the appendix does, if anything. The removal of the appendix does not seem to affect a person’s health. The inside portion of the appendix is called the appendiceal lumen. The mucus that the appendix creates travel through the appendiceal lumen and empties into the large intestine.

Illustration of the digestive tract, showing the location of the appendix.Causes

Appendicitis is commonly caused by obstruction of the appendix’x lumen. This can cause bacteria that normally live inside the appendix to multiply. As a result, the appendix becomes infected and become swollen. Obstruction of the appendix can be caused by

 feces, parasites, or growths that clog the appendiceal lumen
 enlarged lymph tissue in the wall of the appendix, caused by infection in the gastrointestinal tract or elsewhere in the body
 inflammatory bowel disease, including Crohn’s disease and ulcerative colitis
 trauma to the abdomen

There is danger of the inflamed appendix to burst. When this happens, the infection can spread to nearby organs in the abdomen—a condition called peritonitis. This is a potentially dangerous condition, which requires immediate medical care.

Symptoms of Appendicitis

The most common symptom of appendicitis is pain in the abdomen. The abdominal pain usually

 occurs suddenly, often causing a person to wake up at night
 occurs before other symptoms
 begins near the belly button and then moves lower and to the right
 is new and unlike any pain felt before
 gets worse in a matter of hours
 gets worse when moving around, taking deep breaths, coughing, or sneezing
Other symptoms of appendicitis may include
 loss of appetite
 nausea
 vomiting
 constipation or diarrhea
 inability to pass gas
 a low-grade fever that follows other symptoms
 abdominal swelling
 the feeling that passing stool will relieve discomfort
Diagnosis of Appendicitis

A doctor or other health care provider can diagnose most cases of appendicitis by taking a person’s medical history and performing a physical examination. If a person shows classic symptoms, a doctor may suggest surgery right away to remove the appendix before it bursts.

Doctors may use laboratory and imaging tests, such as blood tests, computed tomography (CT) scans, and abdominal x ray to confirm appendicitis if a person does not have classic symptoms. Tests may also help diagnose appendicitis in people who cannot adequately describe their symptoms, such as children or the mentally impaired.

Treatment of Appendicitis

Surgery

Typically, removing the appendix treats appendicitis. If appendicitis is suspected, a doctor will often suggest surgery without conducting extensive diagnostic testing. Prompt surgery decreases the likelihood the appendix will burst.

Surgery to remove the appendix is called appendectomy and can be done two ways. The older method, called laparotomy, removes the appendix through a single incision in the lower right area of the abdomen. The newer method, called laparoscopic surgery, uses several smaller incisions and special surgical tools fed through the incisions to remove the appendix. Laparoscopic surgery leads to fewer complications, such as hospital-related infections, and has a shorter recovery time.

Surgery occasionally reveals a normal appendix. In such cases, many surgeons will remove the healthy appendix to eliminate the future possibility of appendicitis. Occasionally, surgery reveals a different problem, which may also be corrected during surgery.

Sometimes abscess forms around a burst appendix—called an appendiceal abscess. An abscess is a pus-filled mass that results from the body’s attempt to keep an infection from spreading. An abscess may be addressed during surgery or, more commonly, drained before surgery. To drain an abscess, a tube is placed in the abscess through the abdominal wall. CT is used to help find the abscess. The drainage tube is left in place for about 2 weeks while antibiotics are given to treat infection. Six to 8 weeks later, when infection and inflammation are under control, surgery is performed to remove what remains of the burst appendix.

Nonsurgical Treatment

Nonsurgical treatment may be used if surgery is not available, if a person is not well enough to undergo surgery, or if the diagnosis is unclear. Some research suggests that appendicitis can get better without surgery. Nonsurgical treatment includes antibiotics to treat infection and a liquid or soft diet until the infection subsides. A soft diet is low in fiber and easily breaks down in the gastrointestinal tract.

Recovery

With adequate care, most people recover from appendicitis and do not need to make changes to diet, exercise, or lifestyle. Full recovery from surgery takes about 4 to 6 weeks. Limiting physical activity during this time allows tissues to heal.
