Can you have lactose intolerance and ulcerative colitis?

ANSWER

Some people can't digest lactose, which is the sugar in milk. That's true even for people who don't have an inflammatory bowel disease. But because the symptoms of lactose intolerance look a lot like some symptoms of UC, it may be hard to tell if milk is causing the problem. Your doctor can test you to see if you're lactose intolerant.
