Endoscopy FAQs

Endoscopy FAQs

What is endoscopy?

Endoscopy is a medical procedure used to view the digestive tract, and other internal organs, without an operation. Using an endoscope (a thin rubber tube with a lighted camera attached), the internal body structures can be seen enlarged on a video monitor by the physician.

Where is the endoscope inserted?

The endoscope can be inserted through the mouth (upper endoscopy or EGD), or through the rectum (colonoscopy)

Why is an endoscopy performed?

It is done to diagnose the cause of abdominal pain, acidity, gas, loss of appetite or weight, change in bowel habits, ‘piles’ (hemorrhoids) and bleeding. Diseases such as ulcers, esophageal, stomach or bowel cancer, polyps and colitis are easily diagnosed using endoscopy. Endoscopy can also be used to treat certain conditions.

Can I get both consultation and endoscopy done on the same day?

If you wish to have an endoscopy done, it is better to call earlier and schedule an appointment. Walk-in endoscopy can also be done, but only on days with lighter schedules.

How should I prepare for a colonoscopy?

Detailed instructions will be given at the hospital at the time of scheduling, along with the medicines required to do the bowel preparation. You should be on clear liquids (water, Sprite, black tea/coffee, clear juice without pulp) for 24 hours prior to colonoscopy, starting from the previous morning. That afternoon, you may take the prescribed laxative at home. You should arrive at the hospital next morning, at least an hour before your appointment.

Do I need to starve before an endoscopy?

You should not have eaten solid food for at least 8 hours prior to upper endoscopy. However, you may have water or black tea/coffee up to 2 hours prior to the procedure.

Are there any limitations after endoscopy?

Since it is done under IV sedation, you should not drive a motor vehicle for 24 hours after the procedure. There is no restriction on diet.

Is sedation mandatory?

No. In fact, the majority of endoscopies in India are done without sedation. However, it is much more comfortable to undergo the procedure under light IV sedation, which incidentally is the accepted standard in America.

What is a screening colonoscopy?

It is done on healthy persons over age 50, looking for polyps (small growths on the bowel wall) which are the earliest form of colon cancer. One out of 3-4 people over age 50 have polyps, which are silent, without symptoms. Removal of polyps at colonoscopy will greatly reduce the risk of colorectal cancer, which is the no.2 cause of cancer deaths worldwide, and one of the few genuinely preventable cancers. Countries like America, Europe, Singapore and China are already doing it as part of their routine health check-up at age 50.
