What is Ulcerative Colitis?

Ulcerative colitis is a chronic disease of the large intestine, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers. This condition is the result of your immune system’s overactive response.


A chronic disease diagnosis can be scary, but learning all you can about your illness and how to manage your symptoms will put you on the path to better health and wellness. We can help you with information and resources to get you feeling better physically and emotionally.
