How would you describe your UC?

The number of stools per day that is “normal” is different for everyone. To figure out what’s normal for you, think about the number of bowel movements you have when you are feeling well, for example before you were diagnosed with UC or when your UC was completely controlled.

Monitoring disease activity

Your health care provider will monitor the activity of your UC to check the symptoms of your disease at a certain point in time. This is called treat-to-target. The goal is to get to and maintain remission (no signs or symptoms of active UC).

Once you and your health care provider talk about the treatment goals, your provider will order periodic tests to monitor your UC. These may include some of the tests used when you received your diagnosis, including blood tests, stool tests, and imaging.
