Most colonoscopies are done to screen for colorectal cancer. Some, though, are diagnostic, per the American Gastroenterological Association. That means they’re done to try to find a reason for unexplained symptoms like bleeding or weight loss. If you have a diagnostic colonoscopy and your doctor confirms that you have a particular medical condition, such as Crohn’s disease, you may need to go on what’s called a “therapeutic diet” designed to control or treat that condition, Msora-Kasago says. In this case, your doctor will help you determine what foods are best for you.

You may lose some weight after a colonoscopy because of the food limitations before the procedure, but you’ll likely return to your normal weight soon after you start eating your regular diet again.
