Symptoms and features
Ongoing belly pain, diarrhea, weight loss, and fatigue are common, and anal fistulas or abscesses can be the first clue. Inflammation goes through the full thickness of the bowel wall in patchy "skip lesions," which can lead to narrowing or fistulas. That sets it apart from ulcerative colitis, and unlike IBS, colonoscopy shows real inflammation.
Treatment and daily life
The goal is remission, not a cure. Steroids calm flares, while immunomodulators and biologics such as anti-TNF drugs maintain control. Smoking makes Crohn's worse, so quitting is one of the most effective steps. There's no single Crohn's diet; people with strictures may need to limit high-fiber foods, and a dietitian can help tailor choices.
