How to Prepare for a Routine Colonoscopy for Crohn’s

What to Expect After a Colonoscopy

In most cases, here’s what you can expect once the procedure’s over and you’re back at home.

Avoid Activities for 24 Hours After the Procedure

As with any procedure that involves sedation with anesthesia, Philpott and Iskandar say to avoid any activities for 24 hours that require you to be in an unaltered state of mind. This includes driving or operating any heavy or dangerous machinery, climbing high ladders, and even signing important documents or contracts. They also advise against drinking alcohol during the same 24-hour period. “Expect to rest the day of the procedure and not work,” Iskandar says.

Avoid Gassy or Irritating Foods Right After a Colonoscopy

According to Philpott, most people feel fine after the procedure and can go right back to eating normal foods. But she advises avoiding any gassy, high-fiber foods for a day or two.

“Gassy foods won’t injure you, but they might make you uncomfortable, because you’re going to have a little gas after the procedure,” she says.

Iskandar says that some mild cramping, gas, and bloating are normal due to the air that enters the colon during the procedure. Altered bowel movements and small streaks of blood right after also aren’t cause for alarm, but if you experience severe pain or bleeding, see your doctor immediately.

Keep Diligent Records Once You Get Home

Maintaining a file of medical care records is key for anyone with a chronic condition. “When people have a colonoscopy, we print out the pictures for them,” says Philpott. “These pictures often aren’t included in electronic medical records.”

A binder with a summary of your medical history, medication list, test results, other records, and images from your colonoscopies can help you understand how your condition has changed over time and will be especially helpful if you switch to a new doctor.

Know That It Gets Easier

If you’ve already been diagnosed with Crohn’s, the good news is that the most challenging colonoscopy you’ll experience is likely already out of the way. “When you have inflammatory bowel disease, your first colonoscopy is often the roughest, because it’s being done while you’re sick,” says Philpott.

Subsequent colonoscopies are often easier, because you’re aware of the process and inflammation and symptoms are being treated. She also says that there isn’t any increased stress to your body from having multiple colonoscopies.

While a colonoscopy may disrupt your routine and require prep beforehand, Iskandar says that it’s essential for successfully managing Crohn’s, reaching remission, and preventing any long-term Crohn’s-related complications.
