Ulcerative colitis


Your colon is your large intestine (bowel). Your rectum is the end of your bowel, where poo is stored.

If you have ulcerative colitis, you get swelling, inflammation and ulcers in the lining of your large bowel. They can bleed and produce pus.

Ulcerative colitis can affect people of all ages, but it’s usually diagnosed between the age of 15 and 40.
