Colorectal cancer is one of the most preventable cancers, yet many people still put off their screening colonoscopy because they are worried about one thing: the preparation. Dr. Adam Coe, Gastroenterologist at HMG Gastroenterology, sat down with us to talk about why screening matters, how the prep has changed, and what patients can expect today. His message is simple. The prep is easier than ever, and the screening can save your life.

When to Start Colonoscopy Screening
Screening for colorectal cancer is now recommended to begin at age 45, after national guidelines lowered the starting age from 50 due to increasing rates of colon cancer in younger adults. People with a family history of colorectal cancer or polyps may need to start screening sooner. Dr. Coe encourages everyone to talk with their primary care provider to decide on the screening plan that best supports their health.
“Colonoscopy helps prevent up to 90 percent of colon cancers,” Dr. Coe explains. “It is one of the most powerful tools we have for early detection.”
Why the Prep Should Not Scare You
When patients hear the word “colonoscopy,” many immediately think of the prep. A national survey found that 45 percent of adults who avoid colonoscopy cite fear of the prep as their main reason. Most of these worries come from outdated stories about large volumes of unpleasant liquids and hours of discomfort.
Dr. Coe reassures patients that those days are largely behind us.
“The prep is by far the worst part, but the fears are outdated,” he says. “Prep today is much easier. The volume is smaller. The taste is better. Some patients can even use a pill prep. It has come a long way.”
How Colonoscopy Prep Has Improved
Prep options today are designed to be easier, more personalized, and more tolerable than ever. Dr. Coe shared some of the biggest changes:
- Lower volume solutions that require drinking much less liquid
- Better flavors and improved formulas
- More hydration with liquids you already enjoy
- A pill prep option for select patients
- Split dosing for improved comfort and effectiveness
“It is not the old two‑gallon jug anymore,” Dr. Coe says. “Most patients are surprised at how manageable it is.”

Tips to Make Prep Day Easier
Dr. Coe offers simple steps that can reduce anxiety and help the prep go smoothly:
- Read your prep instructions ahead of time
- Ask your care team questions before prep day
- Keep your schedule clear so you can stay home and comfortable
- Stock up on clear liquids you enjoy
- Stay well hydrated leading up to the prep
- Follow instructions closely to avoid needing to repeat the procedure
“Being prepared reduces most of the stress patients feel,” Dr. Coe explains.
What Patients Say Afterward
For many, the fear is far worse than the experience.

“Most tell us it was not nearly as bad as they expected,” Dr. Coe shares. “Patients who put it off usually say they wish they had done it sooner.”
Why You Should Not Delay Your Screening
Delaying a colonoscopy because of prep fears can have serious consequences. Colonoscopy can detect polyps and many can be removed during the same procedure. This means cancer can often be prevented before it starts.
“When we screen appropriately, we catch cancer or polyps at the earliest stage,” Dr. Coe explains. “That is when outcomes are best and treatment options are greatest.”
The best part? The procedure itself typically takes only 15 to 20 minutes. Most patients go home shortly afterward and many go out to eat the same day.
A Few Minutes That Can Save a Life
During March, Colorectal Cancer Awareness Month, Dr. Coe encourages patients not to let fear stand in the way of their health.
“The prep is easier. The procedure is safer. And those 15 to 20 minutes can make a huge difference in your life and your family’s life,” he says.
If you are 45 or older or have risk factors for colorectal cancer, do not wait to take this important step for your health. A screening colonoscopy is simple, the prep is easier than ever, and the procedure itself could prevent something life changing. You can schedule with an HMG primary care provider online 24/7, making it easier than ever to get the care you need when it works for you.
