Eating, Diet, & Nutrition for Microscopic Colitis

What should I eat and drink if I have microscopic colitis?

Scientists have not yet discovered dietary changes that heal microscopic colitis. However, in some cases, doctors may recommend changing what you eat and drink to help improve diarrhea symptoms. Changing what you eat and drink can also help reduce symptoms if you have another digestive disorder—such as lactose intolerance or celiac disease—in addition to microscopic colitis.

Depending on your symptoms and health conditions, doctors may recommend limiting or avoiding

  • alcohol
  • artificial sweeteners
  • caffeine
  • foods and drinks that contain gluten if you have celiac disease
  • milk and milk products if you have lactose intolerance

Talk with your doctor about what foods and beverages are best for you.
