K50-K52: Noninfective enteritis and colitis

K51: Ulcerative colitis

Ulcerative colitis is part of a group of conditions known as inflammatory bowel diseases. It is characterized by long-term inflammation and ulcers, or sores, in the innermost lining of your large intestine (colon) and rectum. This chronic disease primarily affects the digestive system and can lead to severe discomfort and various health complications. The exact cause of ulcerative colitis remains unknown, though it is believed to occur due to an overactive immune system response. Common symptoms include abdominal pain, bloody stools, urgent bowel movements, fatigue, weight loss, and in some cases, fever. The progression of this condition varies between individuals, with some experiencing mild symptoms while others suffer severe, acute flare-ups. Over time, the continuous inflammation and ulceration can significantly impact the function of the colon, leading to more serious health risks.
