Gastroesophageal reflux disease, or GERD, occurs when the muscle located at the end of your esophagus--called the lower esophageal sphincter (LES)--does not close properly. Your esophagus is the tube that carries food from your mouth to your stomach. Because your LES does not close properly when it should, your stomach contents leak back, or reflux, into your esophagus and irritate it.

Gastroesophageal reflux disease Symptoms

Most people who have gastroesophageal reflux disease feel a burning sensation in their chest or throat. This is called heartburn. Sometimes, you can taste stomach fluid in the back of the mouth. This is acid indigestion. If you have these symptoms for two weeks in a row or more, you may have GERD.

Who gets reflux disease?

Anyone can have Gastroesophageal reflux disease, including infants and children.

Hiatal hernia is a digestive problem in which a part of your stomach protrudes through the opening of your diaphragm. Your diaphragm is a thin sheet of muscle that helps your breathe. It also separates your chest from your abdomen.

The opening in your diaphragm, called the hiatus, is normally just large enough to allow your esophagus to pass, but prevents your stomach to push upward beyond your diaphragm. The esophagus is the tube connecting your mouth to your stomach.

Causes Hiatal Hernia

The true cause of hiatal hernia is unknown. However, experts believe that it may be associated with weakening of the hiatus or surrounding tissues.

Some people may be at risk of developing hiatal hernia, such as

Advancing age
• Being overweight or obese
• Smoking
• Pregnancy

Hiatal Hernia Symptoms

Most cases of hiatal hernia have no symptoms. Sometimes, hiatal hernia symptoms are associated with gastroesophageal reflux disease, or GERD, which may include heartburn, chest pain and difficulty swallowing.

If your symptoms seem to persist, get medical help.

Hiatal Hernia Treatment

Mild hiatal hernia that does not cause symptoms usually does not need special medical treatment. If your condition causes symptoms, you may need treatment. Your doctor may recommend medications to relieve your symptoms caused by GERD.

Surgery may be the last option if your symptoms are not relieved by medication.

Proctitis is a digestive disease in which the inner lining of the rectum, called rectal mucosa, is inflamed. It can be acute (short term) or chronic (long term) proctitis.

Causes

There are several causes of proctitis. Sometimes inflammation of the rectum is caused by sexually transmitted diseases, such as herpes, gonorrhea, or chlamydia. In other cases, the condition is associated with autoimmune digestive conditions causing inflammation in the colon or small intestine like ulcerative colitis or Crohn's disease. Proctitis may also be the result of certain medical treatments, such as radiation therapy or antibiotics.

Other causes of proctitis may include:

• injury to the rectum (rectal injury)
• bacterial infection
• malfunctioning nerves in the rectum
• allergies

Symptoms

The most common symptom of proctitis is frequent or continuous urge to have a bowel movement. Other symptoms may include:

• constipation
• a feeling of rectal fullness
• left-sided abdominal pain
• passage of mucus through the rectum
• bleeding in the rectum
• pain in the rectum or anus (anorectal pain)

Diagnosis

Physicians diagnose proctitis by looking inside the rectum with a proctoscope or a sigmoidoscope. A biopsy (a tiny piece of tissue from the rectum) may be removed and tested for diseases or infections. A stool sample may also reveal infecting bacteria. If the physician suspects Crohn's disease or ulcerative colitis, colonoscopy or barium enema x rays may be used to examine areas of the intestine.

Treatment

Treatment of proctitis depends on the specific cause. For example, the physician may prescribe antibiotics for proctitis caused by bacterial infection. If the inflammation is caused by Crohn's disease or ulcerative colitis, the physician may recommend the drug 5-aminosalicyclic acid (5ASA) or corticosteroids applied directly to the area in enema or suppository form, or taken orally in pill form. Enema and suppository applications are usually more effective, but some patients may require a combination of oral and rectal applications.

Gastroesophageal reflux (GER) occurs when stomach contents reflux, or back up, into the esophagus during or after a meal. The esophagus is the tube that connects the mouth to the stomach. A ring of muscle at the bottom of the esophagus opens and closes to allow food to enter the stomach. This ring of muscle is called the lower esophageal sphincter (LES).

The LES normally opens to release gas after meals. With infants, when the LES opens, stomach contents often reflux into the esophagus and out the mouth, resulting in regurgitation, or spitting up, and vomiting. GER can also occur when babies cough, cry, or strain.

Symptoms

GER is common in healthy infants. More than half of all babies experience reflux in the first 3 months of life, but most stop spitting up between the ages of 12 to 24 months. Only a small number of infants have severe symptoms. An infant with GER may experience

* spitting up
* vomiting
* coughing
* irritability
* poor feeding
* blood in the stools

In a small number of babies, GER results in symptoms that cause concern. These symptoms include

* poor growth due to an inability to hold down enough food
* irritability or refusing to feed due to pain
* blood loss from acid burning the esophagus
* breathing problems

These problems can be caused by disorders other than GER. Your health care provider will need to determine whether GER is the cause of your child’s symptoms.

Diagnosis

A baby who is consistently spitting up or vomiting may have GER. The doctor or nurse will talk with you about your child’s symptoms and examine your child. Tests may be ordered to help determine whether your child’s symptoms are related to GER. Sometimes treatment is started without tests. If the infant is healthy, content, and growing well, often no tests or treatment are needed.

Treatment

The treatment for baby reflux depends on an infant’s symptoms and age. Some babies may not need treatment because GER often resolves by itself. Healthy babies may only need their feedings thickened with cereal and to be kept upright after eating. Overfeeding can aggravate reflux, so your health care provider may suggest different ways of handling feedings. For example, smaller quantities with more frequent feedings can help decrease the chances of regurgitation. If a food allergy is suspected, you may be asked to change the baby’s formula.

Breastfeeding mothers may be asked to change their own diets for 1 to 2 weeks. If a child is not growing properly, higher-calorie food or tube feeding may be recommended.

When an infant is uncomfortable, has difficulty sleeping or eating, or does not grow, your health care provider may suggest a trial of medication to decrease the amount of acid in the stomach. Any potential complications related to the medication will be explained. However, most infants don’t need medication and outgrow reflux by 1 or 2 years of age.

*If medication is needed, treatment will often start with a class of medications called H2-blockers, also called H2-receptor agonists. These drugs help keep acid from backing up into the esophagus. H2-blockers are often used to treat children with GER because they come in liquid form. H2-blockers include

Call your child’s health care provider right away if any of the following occur:

* vomiting large amounts or persistent projectile (forceful) vomiting, particularly in infants younger than 2 months old
* vomiting fluid that is green or yellow or that looks like coffee grounds or blood
* difficulty breathing after vomiting or spitting up
* refusing food that seems to result in weight loss or poor weight gain
* excessive crying and irritability

Dyspepsia, also known as indigestion, 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.

This digestive condition is common in adults and can occur once in a while or as often as every day.

Dyspepsia Causes

Dyspepsia can be caused by a condition in the digestive tract such as gastroesophageal reflux disease (GERD), peptic ulcer disease, cancer, or abnormality of the pancreas or bile ducts. If the condition improves or resolves, the symptoms of indigestion usually improve.

Sometimes a person has indigestion for which a cause cannot be found. This type of indigestion, called functional dyspepsia, is thought to occur in the area where the stomach meets 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.

Symptoms of Dyspepsia

Most people with indigestion experience 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.

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.

Sometimes the term dyspepsia is used to describe the symptom of heartburn, but these are two different conditions. Heartburn is a painful, burning feeling in the chest that radiates toward the neck or back. Heartburn is caused by stomach acid rising into the esophagus and may be a symptom of GERD. A person can have symptoms of both indigestion and heartburn.

Diagnosis

To diagnose indigestion, the doctor asks about the person’s current symptoms and medical history and performs a physical examination. The doctor may order x rays of the stomach and small intestine.

The doctor may perform blood, breath, or stool tests if the type of bacteria that causes peptic ulcer disease is suspected as the cause of indigestion.

The doctor may perform an upper endoscopy. After giving a sedative to help the person become drowsy, the doctor passes an endoscope—a long, thin tube that has a light and small camera on the end—through the mouth and gently guides it down the esophagus into the stomach. The doctor can look at the esophagus and stomach with the endoscope to check for any abnormalities. The doctor may perform biopsies—removing small pieces of tissue for examination with a microscope—to look for possible damage from GERD or an infection.

Because indigestion can be a sign of a more serious condition, people should see a doctor right away if they experience

* frequent vomiting
* blood in vomit
* weight loss or loss of appetite
* black tarry stools
* difficult or painful swallowing
* abdominal pain in a nonepigastric area
* indigestion accompanied by shortness of breath, sweating, or pain that radiates to the jaw, neck, or arm
* symptoms that persist for more than 2 weeks

Treatment of Dyspepsia

Some people may experience relief from symptoms of indigestion by

* eating several small, low-fat meals throughout the day at a slow pace
* refraining from smoking
* abstaining from consuming coffee, carbonated beverages, and alcohol
* stopping use of medications that may irritate the stomach lining—such as aspirin or anti-inflammatory drugs
* getting enough rest
* finding ways to decrease emotional and physical stress, such as relaxation therapy or yoga

The doctor may recommend over-the-counter antacids or medications that reduce acid production or help the stomach move food more quickly into the small intestine. Many of these medications can be purchased without a prescription. Nonprescription medications should only be used at the dose and for the length of time recommended on the label unless advised differently by a doctor. Informing the doctor when starting a new medication is important.

Antacids, such as Alka-Seltzer, Maalox, Mylanta, Rolaids, and Riopan, are usually the first drugs recommended to relieve symptoms of indigestion. Many brands on the market use different combinations of three basic salts—magnesium, calcium, and aluminum—with hydroxide or bicarbonate ions to neutralize the acid in the stomach. Antacids, however, can have side effects. Magnesium salt can lead to diarrhea, and aluminum salt may cause constipation. Aluminum and magnesium salts are often combined in a single product to balance these effects.

Calcium carbonate antacids, such as Tums, Titralac, and Alka-2, can also be a supplemental source of calcium, though they may cause constipation.

H2 receptor antagonists (H2RAs) include ranitidine (Zantac), cimetidine (Tagamet), famotidine (Pepcid), and nizatidine (Axid) and are available both by prescription and over-the-counter. H2RAs treat symptoms of indigestion by reducing stomach acid. They work longer than but not as quickly as antacids. Side effects of H2RAs may include headache, nausea, vomiting, constipation, diarrhea, and unusual bleeding or bruising.

Proton pump inhibitors (PPIs) include omeprazole (Prilosec, Zegerid), lansoprazole (Prevacid), pantoprazole (Protonix), rabeprazole (Aciphex), and esomeprazole (Nexium) and are available by prescription. Prilosec is also available in over-the-counter strength. PPIs, which are stronger than H2RAs, also treat indigestion symptoms by reducing stomach acid. PPIs are most effective in treating symptoms of indigestion in people who also have GERD. Side effects of PPIs may include back pain, aching, cough, headache, dizziness, abdominal pain, gas, nausea, vomiting, constipation, and diarrhea.

Prokinetics such as metoclopramide (Reglan) may be helpful for people who have a problem with the stomach emptying too slowly. Metoclopramide also improves muscle action in the digestive tract. Prokinetics have frequent side effects that limit their usefulness, including fatigue, sleepiness, depression, anxiety, and involuntary muscle spasms or movements.

If testing shows the type of bacteria that causes peptic ulcer disease, the doctor may prescribe antibiotics to treat the condition.

Abdominal adhesions are bands of tissue that form between abdominal tissues and organs. Normally, internal tissues and organs have slippery surfaces, which allow them to shift easily as the body moves. Adhesions cause tissues and organs to stick together.

Although most adhesions cause no symptoms or problems, others cause chronic abdominal or pelvic pain. Adhesions are also a major cause of intestinal obstruction and female infertility.

Causes

Abdominal surgery is the most frequent cause of abdominal adhesions. Almost everyone who undergoes abdominal surgery develops adhesions; however, the risk is greater after operations on the lower abdomen and pelvis, including bowel and gynecological surgeries. Adhesions can become larger and tighter as time passes, causing problems years after surgery.

Surgery-induced causes of abdominal adhesions include

* tissue incisions, especially those involving internal organs
* the handling of internal organs
* the drying out of internal organs and tissues
* contact of internal tissues with foreign materials, such as gauze, surgical gloves, and stitches
* blood or blood clots that were not rinsed out during surgery

A less common cause of abdominal adhesions is inflammation from sources not related to surgery, including

* appendicitis—in particular, appendix rupture
* radiation treatment for cancer
* gynecological infections
* abdominal infections

Rarely, the condition forms without apparent cause.

Symptoms

Although most abdominal adhesions go unnoticed, the most common symptom is chronic abdominal or pelvic pain. The pain often mimics that of other conditions, including appendicitis, endometriosis, and diverticulitis.

When intestinal obstruction occurs, it can cause other symptoms, such as:

* severe abdominal pain or cramping
* vomiting
* bloating
* loud bowel sounds
* swelling of the abdomen
* inability to pass gas
* constipation

A person with these symptoms should seek medical attention immediately.

Diagnosis

No tests are available to diagnose this digestive disorder, and adhesions cannot be seen through imaging techniques such as x rays or ultrasound. Most adhesions are found during exploratory surgery. An intestinal obstruction, however, can be seen through abdominal x rays, barium contrast studies—also called a lower GI series—and computerized tomography.

Treatment Options

Treatment for abdominal adhesions is usually not necessary, as most do not cause problems. Surgery is currently the only way to break adhesions that cause pain, intestinal obstruction, or fertility problems. More surgery, however, carries the risk of additional adhesions and is avoided when possible.

A complete intestinal obstruction usually requires immediate surgery. A partial obstruction can sometimes be relieved with a liquid or low-residue diet. A low-residue diet is high in dairy products, low in fiber, and more easily broken down into smaller particles by the digestive system.
