Some issues Dr. Syed Ismail M. Thiwan, MD can help you with:

Colonoscopy

Colonoscopy is the use of a special tool called a colonoscope (a thin, flexible tube with a camera on the end) to examine the inside of the colon and rectum. The tube is typically inserted anally, and it allows the physician to examine the large intestine from the inside. It may be done at any time to diagnose bowel problems, but routine colonoscopies are advised after the age of 50 to screen for colon cancer.

A colonoscopy may be performed to diagnose:

Intestinal ulcers
Polyps
Bowel cancer
An unidentified source of pain or bleeding in the intestine

Patients may be asked to drink only liquids in the days before a colonoscopy, or they may be given an enema to remove residual fecal matter. Before the exam, patients are given medication to help them relax, and then lay on their side on a table. The scope is inserted into the anus and gently moved all the way through the large intestine. Air may be pumped into the intestine to improve the view for the physician. Any polyps that are found will be removed. Then the colonoscope will be withdrawn. A colonoscopy is not usually painful, but patients may feel some bloating or have some cramps right afterward. If patients have polyps removed, they might experience a small amount of bleeding. Any side effects should go away within a few hours.
