Colonoscopies save lives. But before you schedule one, you probably have some questions — and maybe a few concerns.
We took some of the most common questions to Charles Adelmann, MD, a gastroenterologist with Soundview Medical Associates, in partnership with Hartford HealthCare. Here’s what you need to know — and how to schedule your colonoscopy.
1. How often do you need a colonoscopy?
Your colonoscopy schedule depends on your risk factors.
“While the American Cancer Society recommends starting colon cancer screenings at age 45 for average-risk individuals and repeating them every 5–10 years, your personal risk may require a different timeline,” explains Dr. Adelmann.
You might need an earlier or more frequent screening if you have:
- A family history of colon cancer.
- Previous or existing colon polyps (growths that can become cancerous).
“Your doctor will help figure out the right schedule for you based on your history and what they find during the procedure,” adds Dr. Adelmann.

2. Do you get put to sleep for a colonoscopy?
Yes – most patients are sedated and comfortably asleep during the procedure.
“Sedation helps keep you relaxed and comfortable while your doctor checks your colon,” says Dr. Adelmann. “Your care team will explain everything beforehand so you know what to expect before and after your colonoscopy.”

3. How long does it take to get a colonoscopy?
Scheduling a colonoscopy is easier than you might think.
“Most elective colonoscopies can happen within a month or two of your first call,” says Dr. Adelmann. “And if you have concerning symptoms, we’ll prioritize getting you in sooner.”
And the actual procedure is even quicker.
“The colonoscopy itself usually takes 30–60 minutes,” explains Dr. Adelmann. “But with preparation and recovery time, the whole appointment typically lasts two to three hours.”
4. What should I eat for colonoscopy prep?
It’s not so much about what’s on your plate – it’s about what’s in your glass.
“You’ll get detailed prep instructions from your doctor, but the day before, you’ll stick to clear liquids for 24 hours,” explains Dr. Adelmann.
That means skipping solid foods and going for options like water, broth or pulp-free juice. This essential prep helps your doctor see everything clearly during the procedure.

5. How long will diarrhea last from colonoscopy prep?
While it’s not the most pleasant part of the process, diarrhea is a normal sign that your colon is clearing out for the procedure.
“Everyone responds a little differently, but you can expect multiple watery bowel movements for a few hours after taking the prep,” says Dr. Adelmann. “If you have concerns, don’t hesitate to reach out to your doctor.”
6. Can I drive after a colonoscopy?
No – and it’s all about keeping you safe.
“The sedation makes it unsafe to drive for 24 hours after your colonoscopy,” says Dr. Adelmann. “Be sure to plan ahead and have someone ready to take you home.”
7. How much does a colonoscopy cost?
Most insurance plans cover colonoscopies for colorectal cancer screening.
“It’s a good idea to check with your insurance ahead of time to understand any out-of-pocket costs,” says Dr. Adelmann. “Getting this sorted early helps avoid surprises on procedure day.”
