Crohn's disease is a type of inflammatory bowel disease that can cause problems in the digestive system. It happens when the body's immune system mistakenly attacks the digestive tract, causing inflammation. This can lead to symptoms like stomach pain, diarrhea, weight loss, and fatigue. Crohn's disease can affect any part of the digestive tract, from the mouth to the anus. While there's no cure for Crohn's disease, treatments like medication, diet changes, and sometimes surgery can help manage symptoms and reduce inflammation, allowing people with Crohn's to live relatively normal lives with proper care.
