What is a colonoscopy?

Colonoscopy is a method of looking inside a person’s large intestine (colon). Polyps are growths in the colon that can turn into cancer.

If you have polyps, the doctor can usually remove them during a colonoscopy.

What are the other reasons my doctor wants a colonoscopy?

Your doctor may order a colonoscopy if:

  • rectal bleeding,

  • Change in your bowel habits

  • a condition called anemia (anemia), which can make you feel tired and weak

  • Long-term abdominal or rectal pain that you cannot explain,

  • Abnormal results from a different colon test

  • A history of colon cancer or polyps in your colon.

What should I do before colonoscopy?

Your doctor will give you information about what to do before a colonoscopy. They will tell you what foods you can and cannot eat. They will also tell you if you need to stop taking any of your usual medications ahead of time.

You may need to stop some medications up to a week before the test. Colon must be cleaned before colonoscopy. Your doctor will give you a special drink that causes watery diarrhea. It’s important to drink all of it to make sure your colon is clean.

If your colon is clear, your doctor will take a better look inside your colon. A clean colon also makes testing easier and more comfortable. Let your doctor know if you’re having trouble preparing for your colonoscopy.

What happens during a colonoscopy?

The anesthesiologist will give you medicine to relax and not feel pain, so you can sleep. Then, your doctor will enter your large intestine from the rectum with a thin tube with a camera and light at the end and examine the inner surface of the colon.

During the procedure, your doctor may perform a test called a biopsy. During the biopsy, a small piece of tissue is taken from the colon. Then they look at the tissue under a microscope to see if there is cancer. Your doctor may also remove polyps they see in the colon. You won’t feel it if the doctor takes a biopsy or removes a polyp.
