Conditions We Diagnose With Colonoscopy at Cleveland Clinic
Colon polyps are growths that form in the lining of the colon. These growths may also form in the rectum. Over time, polyps may become colorectal cancer.
Cancers of the colon and rectum (colorectal cancer) are highly treatable when caught early. That’s why experts recommend a colonoscopy every 10 years for people who are at average risk for colon cancer. If colon cancer runs in your family, your healthcare provider may recommend more frequent screenings.
We use colonoscopies to find and examine polyps. Our experts often remove any polyps they find during the same procedure. Colonoscopy also helps our specialists diagnose conditions like Crohn’s disease, microscopic colitis and ulcerative colitis.
Our experts also use a colonoscopy to diagnose causes of rectal bleeding. These causes may include:

What to Expect During Your Colonoscopy at Cleveland Clinic
During a colonoscopy, specialists use a colonoscope (the flexible tube with a light and camera) to view your colon. If you choose, we give you medication (anesthesia) so you’ll be asleep during the procedure. The colonoscopy procedure includes:
Colonoscopy prep
A few weeks before your procedure, your provider will talk with you about how to prepare for your colonoscopy, including the bowel preparation instructions you will need to follow. It’s important that your intestine (bowel) is empty so your provider can see the detail of your colon. During the day (or night) before your colonoscopy, you’ll need to drink a solution that helps you poop and completely empty your bowel.
We work with you to make sure you’re able to prepare for colonoscopy in an effective way that’s comfortable for you. Talk with your provider if you have any concerns about how to prepare.
Be sure to let your provider know about all medications you take, including any over-the-counter supplements. You may need to stop taking them prior to this screening.
Colonoscopy procedure
Specialists use a colonoscope to see detailed views of your colon and rectum. Most people choose to have anesthesia and are not awake during the procedure. Talk with your healthcare provider if you have concerns about anesthesia.
If our experts need to remove polyps during colonoscopy, they insert instruments through the colonoscope to remove tissue. Most colonoscopies take less than one hour.
After your colonoscopy at Cleveland Clinic
Once our specialists complete the colonoscopy, you’ll stay in a recovery room until you wake up from anesthesia. It’s important to bring someone with you to drive you home.
If you stopped taking medications, your healthcare provider will tell you when you can begin taking them again and resume your activities.
Other Colon Screenings at Cleveland Clinic
Our experts recommend a colonoscopy for most people and consider it to be the “gold standard” for colorectal cancer screenings. But if colonoscopy isn’t right for you and you are not high risk for cancer, we may recommend:
- Virtual colonoscopy — a computed topography (CT) scan that looks for polyps in your colon and rectum
- Stool-based test — an at-home screening that looks for blood or genetic mutations in your poop (often known by the brand name Cologuard® or called a FIT-DNA test, or fecal immunochemical test)
If a stool/fecal test comes back positive, you should schedule a colonoscopy right away so we can find the underlying cause.
Taking the Next Step
A colonoscopy may not be something you want to do. If you’re feeling anxious, afraid or just don’t know how to fit it into your schedule, know that we’re here for you. And you may have other, less-invasive options. Either way, our providers understand and are there to answer any questions you might have. Getting screened regularly is an important part of maintaining your health and preventing future conditions, like cancer. We’ll be with you through it all.
