Crohn's disease can cause abdominal pain, along with symptoms of diarrhea and intestinal obstruction. It often accompanies fever, anemia, and nutritional disorders. Crohn's disease is an inflammatory bowel disease, and its specific causes are not particularly clear. It commonly affects the terminal ileum and the right half of the colon. The disease course is prone to recurrent attacks, so dietary management is important. The principle of eating small frequent meals should be followed, with a focus on light vegetables, while also ensuring nutritional enhancement. It is advisable to avoid spicy, cold, stimulating foods, and those that cause gas, such as leeks, garlic, and bean products. Treatment involves a combination of medication and surgery.
