What Is A Colonoscopy?

A colonoscopy is a medical procedure used to examine the inside of the large intestine (colon) and rectum. It involves using a long, flexible tube with a camera and light attached to it, called a colonoscope, to view the lining of the colon. The procedure is typically done to screen for colorectal cancer or diagnose intestinal issues such as polyps, ulcers, or inflammation. It is also a way for doctors to monitor and treat certain conditions, such as inflammatory bowel disease (IBD).
Who Needs A Colonoscopy? Is There A Certain Age?
As per current guidelines, individuals at average risk for colorectal cancer should have their first colonoscopy at age 45. If no polyps are detected during the initial colonoscopy, the subsequent screening can be scheduled after 10 years. Regular screenings are recommended between the ages of 45 and 75.
How To Prep For A Colonoscopy?
In order to properly prepare for a colonoscopy, it is important to follow your doctor’s instructions carefully. Typically, this will involve a special diet and fasting the day before the procedure. Your doctor may also give you laxatives or enemas to help clear out your colon. It is important to follow all preparation steps as directed in order to ensure an accurate and successful colonoscopy.
How A Colonoscopy Procedure Affects Your Digestive System?
A colonoscopy procedure can have an impact on your digestive system, potentially resulting in complications. These complications may include continued bleeding following biopsy or polyp removal, as well as symptoms such as nausea, vomiting, bloating, or rectal irritation. Additionally, the preparatory bowel cleansing process can also contribute to these issues.

How long does it take your stomach to heal after a colonoscopy?
The recovery time for the stomach after a colonoscopy varies from person to person.

Most patients typically feel ready to return to normal activities within 24 hours.

After my first colonoscopy, I had subway because I was starving and wanted a little bit of everything. Haven’t had a problem with it yet and something about a post-colonoscopy meal just hits different. Treat yourself afterwards to something delicious
I always go get a steak and cheese from D’Angelo. It’s tradition at this point. Never had a problem, but I have moderate colitis, and have limited issues with foods.
My empty stomach is a terrifying thing. Plus nausea from anesthesia. I usually do something light like egg whites, broth, crackers, apple sauce to start. Or a protein shake. By dinner I’d be eating normally.
