A colonoscopy is a powerful tool for preventing colon cancer and diagnosing gastrointestinal conditions.


A colonoscopy is a critical medical procedure that allows doctors to examine the inner lining of the colon and rectum. Using a long, flexible tube equipped with a camera, Gastroenterologists or Surgeons can diagnose abnormalities, identify the cause of gastrointestinal symptoms, and prevent serious diseases like colon cancer.

During a colonoscopy, the General Surgeon or Gastroenterologist might remove abnormal tissues through the colonoscope.

It's possible to take tissue samples (biopsies) during a colonoscopy.

How is a Colonoscopy Performed?

The General Surgeon or Gastroenterologist uses a colonoscope (a thin tube) that contains a small connected camera. He inserts it into the rectum and moves it inside the large intestine (colon), capturing images and viewing them on a screen.

Why is it Done?

This procedure is conducted for various reasons: to investigate intestinal symptoms, such as bleeding, and to detect and prevent colon cancer. Colonoscopy is the most effective tool for detecting polyps and cancers in the early stages when treatment is most effective.

How to Prepare?

Preparation for a colonoscopy is crucial to ensure accurate results. It includes following a special diet, avoiding certain foods and liquids, and taking a laxative prescribed by the doctor to clean the colon. It's important to follow all the instructions to ensure a successful procedure.

Before, During, and After the Procedure

Before the Colonoscopy

The General Surgeon or Gastroenterologist will review your medical history and ask questions related to your symptoms, lifestyle, medical background, and whether you're taking any medication.

You'll need to empty the colon for colonoscopy preparation, so you should not consume food or drink for 6 to 8 hours before the procedure. You may be asked to take a laxative and use an enema kit the night before the procedure.

Follow all your specialist's instructions.

During the Colonoscopy

Typically, the colonoscopy lasts 30 to 60 minutes, using a sedative to reduce discomfort.

During the procedure, you'll wear a gown lying on the table, bending your knees toward your chest. The general surgeon or gastroenterologist will insert a colonoscope containing a small video camera at the tip, which allows him to view the images through a screen and analyze the inside of the colon.

The specialist might insert instruments through the channel to take tissue samples (biopsies) or remove polyps or other areas of abnormal tissue.

After the Colonoscopy

After the Colonoscopy, you'll be taken to the recovery room, where you can stay for a few hours. The doctor can monitor and review your symptoms while the sedative wears off.

You may experience some symptoms such as:

  • Swelling

  • Stomach discomfort, gas, cramps

Why Does It Help Prevent Colon Cancer?

Colonoscopy can detect precancerous polyps and cancer in its early stages when treatment is more likely to be successful. Removing polyps during a colonoscopy significantly reduces the risk of developing colon cancer in the future.
