Diseases and Conditions

Barrett's Esophagus

Barrett's esophagus is a condition resulting from ongoing irritation of the esophagus where its lining is replaced by the type of lining that is normally found in the stomach. Patients with Barrett's esophagus lack symptoms that are noticeably different from gastroesophageal reflux disease (GERD), the underlying irritation in most cases.

Colon Polyps

A polyp in the colon can be defined as any extra tissue that protrudes into the inside (or lumen) of the large intestine (colon), but typically refers to excess of the lining (epithelium). They vary in size from microscopic to several inches in diameter.


Constipation means that a person has three bowel movements or fewer in a week. The stool is hard and dry. Sometimes it is painful to pass. You may feel 'draggy' and full. Some people think they should have a bowel movement every day. That is not really true. There is no 'right' number of bowel movements. Each person's body finds its own normal number of bowel movements. It depends on the food you eat, how much you exercise, and other things. At one time or another, almost everyone gets constipated. In most cases, it lasts for a short time and is not serious.When you understand what causes constipation, you can take steps to prevent it.

Crohn's Disease

Crohn's disease causes inflammation of parts of the digestive tract. Inflammation is irritation and swelling. The inflammation, mostly caused by sores called ulcers, can cause pain and diarrhea. The digestive tract is the pathway food travels through in the body. This pathway is also called the gastrointestinal, or GI, tract. It goes from the mouth to the anus. Crohn's disease can sometimes be hard to diagnose because its symptoms are like the symptoms of other GI diseases. Crohn's disease can affect any area of the GI tract, but it most often affects a part of the small intestine called the ileum.

Diverticular Disease

Diverticular disease affects the colon. The colon is part of the large intestine that removes waste from your body. Diverticular disease is made up of two conditions: diverticulosis and diverticulitis. Diverticulosis occurs when pouches, called diverticula, form in the colon. These pouches bulge out like weak spots in a tire. Diverticulitis occurs if the pouches become inflamed.

GERD - Gastroesophageal Reflux Disease

GERD (Gastroesophageal Reflux Disease) is a common condition involving the esophagus (the muscular tube that connects the back of the mouth to the stomach) that can occur at any age, but typically begins to appear around age 40. Many people refer to this disorder as heartburn or indigestion. GERD is caused when the muscular valve at the lower end of the esophagus relaxes, allowing the contents of the stomach to backwash, or reflux, into the esophagus. These gastric contents contain strong acids and bile that are very irritating to the lining of the esophagus.


The term hemorrhoids refers to a condition in which the veins around the anus or lower rectum are swollen and inflamed. Hemorrhoids may result from straining to move stool. Other contributing factors include pregnancy, aging, chronic constipation or diarrhea, and anal intercourse. Hemorrhoids are either inside the anus - internal - or under the skin around the anus - external.

Irritable Bowel Syndrome (IBS)

IBS is a functional disorder of the digestive system; that is, it is an abnormality in the way the gut normally functions, but does not have a known specific structural or biochemical alteration. It is sometimes referred to as spastic colon, mucous colitis, spastic colitis, nervous stomach, or irritable colon. Approximately 10-15% of Americans suffer with this disorder, and it is the most common diagnosis made by gastroenterologists. Patients experience a variety of symptoms, particularly abdominal discomfort and a modification of bowel habits. Some people experience constipation, others experience diarrhea, still others experience alternating constipation and diarrhea.

Ulcerative Colitis

Ulcerative colitis is a disease that causes inflammation and sores, called ulcers, in the lining of the rectum and colon. Ulcers form where inflammation has killed the cells that usually line the colon, then bleed and produce pus. Inflammation in the colon also causes the colon to empty frequently, causing diarrhea.
