Colitis and ulcerative colitis, while closely related, differ significantly in their scope and implications for health. Colitis refers to a general inflammation of the colon and can be caused by a variety of factors, including infections, reduced blood flow, certain medications, or allergic reactions, leading to symptoms such as abdominal pain and diarrhea. Ulcerative colitis, on the other hand, is a specific form of colitis that falls under the category of inflammatory bowel disease (IBD). It is characterized by chronic inflammation and the formation of ulcers along the inner lining of the colon and rectum, with symptoms that are often more severe.
