A gastroenterologist, or colonoscopy doctor, is a specialist in identifying and treating gastrointestinal diseases. A colonoscopy doctor in Dallas TX has received special training in this area. These specialists perform far more colonoscopies than any other specialty procedures.

What Is a Colonoscopy?

During a colonoscopy procedure, the doctor checks for abnormalities or disease in the colon. The colon, or lower intestine, is the last part of the gastrointestinal tract; it is attached to the anus via the rectum. The doctor may also gather tissue samples during the procedure. The samples are used for biopsy purposes.

Why Colonoscopies are Performed

There are many reasons why an attending physician would refer his or her patient to a colonoscopy doctor. The procedure is used to screen for cancer as well as:

  • Determine the cause of changes in bowel habits

  • Determine the cause of bleeding or abdominal pain

  • Determine the reason for rapid weight loss, constipation or diarrhea

It is suggested that people over the age of 50 that have an average risk of cancer should see a gastroenterologist every ten years. For those with a higher risk factor, the procedure should be carried out more often. Colonoscopy screenings can prevent colon cancer.

How Is a Colonoscopy Performed?

Before the procedure, you will be instructed on how to prepare yourself. You will be put on a liquid diet consisting of bouillon, sports drinks, or plain tea or coffee. During the evening before the procedure is scheduled, you will be asked to take a laxative and flush your colon.
