K50-K52: Noninfective enteritis and colitis

K50: Crohn disease [regional enteritis]

Crohn's disease, also known as regional enteritis, is a chronic, inflammatory bowel disease that often affects the lining of the digestive tract. This condition can occur in any part of the gut, from the mouth to the anus, but it most commonly impacts the lower part of the small intestine, known as the ileum. Symptoms vary among patients, but often include persistent diarrhea, abdominal pain, fatigue, and weight loss. The exact cause of Crohn's disease is still unclear, but it's thought to involve factors such as genetics, the body's immune system, and environmental triggers. The disease can progress over time, potentially leading to complications such as bowel obstructions or malnutrition due to poor absorption of nutrients. Despite varying in severity among individuals, Crohn's disease often significantly impedes the quality of life due to its chronic nature and recurring symptoms.
