What is a colonoscopy?

A colonoscopy is a type of endoscopy that allows Dr. Shim to view your colon lining in detail. She uses a thin bendable tube, which is inserted through your anus, to slowly move a miniature camera up your ascending colon through to the cecum (the beginning of your colon).

Through this exam, Dr. Shim can detect abnormal lesions like polyps and colon cancer. If you have polyps, Dr. Shim can generally remove them during your colonoscopy. She can also obtain small tissue samples from suspicious areas to perform a biopsy if needed.

Does a colonoscopy hurt?

In the hands of Dr. Shim, a colonoscopy is a painless procedure. Dr. Shim is a compassionate and highly skilled board-certified gastroenterologist with extensive experience in performing colonoscopy and other endoscopic procedures.

You’ll receive medication to help you relax and relieve pain if needed. You’ll lie in a comfortable position on either your side or back during the procedure, which usually lasts only about 20 minutes.

How do I get ready for my colonoscopy?

Colonoscopy preparation procedures depend on the specific type of bowel prep that Dr. Shim prescribes. She may prescribe GoLYTELY®, MoviPrep®, or SUPREP®. Each has its own unique instructions.

With all types of bowel prep, you'll begin on the day before your colonoscopy by having a light breakfast and liquids only for lunch and dinner. Then, you'll fast for a minimum of 6-8 hours (possibly starting at midnight depending on your bowel prep). You may also need to change your medication routine briefly, so be sure to discuss all your current medications with Dr. Shim ahead of your colonoscopy.

Follow all preparation instructions closely, as this allows Dr. Shim to get the clearest images and most reliable results during your colonoscopy.

Are there any restrictions after colonoscopy?

After your colonoscopy, you’ll spend a little time in recovery. The total treatment time for prep, the procedure itself, and recovery is usually less than a couple of hours. After your colonoscopy, a loved one must drive you home. Even though you won’t go to sleep for a colonoscopy, you may be a little drowsy or disoriented afterward and can’t drive for 12 hours.

In the hours after your colonoscopy, you might experience some mild cramps and bloating. This is a normal reaction that happens because the colonoscopy added air to your colon. As soon as you pass gas, these symptoms abate. It’s fine to eat whenever you’re hungry after your colonoscopy.
