Colitis is an inflammation of the inner lining of the colon (large intestine). This condition can cause symptoms such as abdominal pain, diarrhea (often with blood or pus), fatigue, and sometimes weight loss. There are various types of colitis, including:
Ulcerative colitis: A chronic condition that causes long-lasting inflammation and ulcers in the digestive tract, primarily affecting the lining of the large intestine and rectum.
Infectious colitis: Caused by bacteria, viruses, or parasites, leading to temporary inflammation.
Ischemic colitis: Occurs when blood flow to a section of the colon is reduced, resulting in inflammation and damage to the colon tissue.
Microscopic colitis: Includes conditions like collagenous colitis and lymphocytic colitis, which are characterized by inflammation that can only be seen under a microscope.
