What is Gastroenterology?
Gastroenterology is the medical specialty that deals with the diagnosis
and treatment of conditions and diseases which involve the various organs
that make up the digestive system: the esophagus, stomach, duodenum,
small intestine, colon, rectum, liver, gall bladder and pancreas. In Greek,
"gastrus" means stomach and "enteron" refers to the intestine; hence the
What is the role of the Gastroenterologist?
We look for various things that may cause or contribute to a person's
symptoms or distress. External factors such as certain foods, medications
or alcohol can create symptoms, as can emotional factors such as anxiety,
depression, tension and stress. But our most important task is to find or
rule out disease.
What tools do Gastroenterologists use to diagnose illness?
Gastroenterologists have many ways of evaluating digestive problems:
physical examination, endoscopy, colonoscopy, x-ray, ultrasound, nuclear
and CAT-scanning, liver biopsy, and a variety of blood tests.
What problems do Gastroenterologists diagnose and treat?
Of the many diagnoses we deal with, some are simple problems such
as heartburn, swallowing difficulty, indigestion, abdominal pain, excessive
gas, and chronic diarrhea or constipation. Other diagnoses are more
lenging and risk complications, if not treated. These include gall stones,
ulcers, viral or medication-induced hepatitis (liver inflammation), cirrhosis
of the liver, pancreatitis, colitis, ileitis, diverticulitis, intestinal bleeding,
polyps and tumors.
What methods do Gastroenterologists use to treat illness?
Once a diagnosis is made, specific treatment can be planned. Often
this involves simple changes in diet or behavioral modification to reduce
anxiety. Other diagnoses might require the use of medications such as
antibiotics or acid blockers or anti-inflammatory agents. Some problems
can be corrected with endoscopy (from above) or colonoscopy (from be-
low) by cauterizing bleeding ulcers, removing obstructing gall stones,
lasering small tumors or taking out colon polyps (for prevention of
future colon cancer). Occasionally, the services of a surgical consultant
