Crohn’s disease is an inflammatory bowel disease (IBD). It causes inflammation of the lining of your digestive tract, which can lead to abdominal pain, severe diarrhea, fatigue, weight loss and malnutrition. Crohn’s disease can be both painful and debilitating, and sometimes may lead to life-threatening complications.
