What is IBD

Inflammatory bowel disease, or IBD, is a term for a group of chronic conditions that cause inflammation in the digestive tract, mainly Crohn’s disease and ulcerative colitis. Unlike short-term stomach upset, IBD is a long-term disease that can flare up over time and then quiet down in periods of remission. The exact cause of IBD is not fully known, but it is linked to an abnormal immune response that attacks the bowel and causes ongoing inflammation. Genetics and environmental triggers both seem to play a role. Crohn’s disease can affect any part of the digestive tract, from the mouth to the anus, and may involve different layers of the bowel wall. Ulcerative colitis usually affects only the colon and rectum, and it tends to involve the inner lining of the bowel. People with IBD often have abdominal pain, diarrhea, rectal bleeding, fatigue, weight loss, and sometimes fever. Symptoms often come in waves, with flare-ups followed by periods with few or no symptoms. IBD is diagnosed with a mix of symptoms, blood tests, stool tests, imaging, and endoscopy such as colonoscopy. Treatment usually aims to reduce inflammation, control symptoms, and maintain remission using medications, and sometimes surgery is needed. IBD is different from irritable bowel syndrome, or IBS. IBS can cause similar symptoms, but it does not create the same inflammatory damage in the bowel. IBD is a chronic immune-driven disease of the gut that can seriously affect quality of life, but many people do well with the right diagnosis and treatment.
