Ulcerative colitis (UC) is a chronic, remitting-relapsing autoimmune disease of the lining of the colon (large intestine) that can have symptom-free periods followed by flare-ups. This disease course can negatively affect a person's quality of life and normal day-to-day functioning.

Research shows that close to 70 percent of people who have active UC in a given year will have a relapse of symptoms in the next year. A large part of treating UC is preventing the next relapse and keeping it in remission as much as possible. When you have a flare, management aims to relieve symptoms and to end the flare as soon as possible.

The key to dealing with a flare is knowing what caused it and how to fix it.

What are the common triggers of UC flares?

Dealing with flares

Corticosteroids are among the most helpful agents that doctors have to stop a flare. Prednisone and budesonide are two examples. Steroids are not always effective, but they are usually the best agents to try first during a severe flare.

There are five main categories of medication used for treatment, some long-term and others short-term. These include:

Certain lifestyle changes can also help reduce the intensity and frequency of UC flares. There's a link between emotional stress and the severity of UC flares. Stress relief techniques such as hypnosis and meditation may improve symptoms. Other healthy options are yoga, aerobics, and static exercises.

While having chronic diarrhea can be annoying, there are ways you can manage it. Apply soothing pads or diaper rash cream to the area as needed. You should also monitor what you eat. Fiber can be tough on people with UC, because eating it can have unintended consequences. Normally it helps maintain regularity, but it may not be helpful for treating diarrhea. On the other hand, an anti-diarrheal may be useful if you're certain that you don't have a bacterial infection of the bowel.
