Small intestinal ulcers and Crohn's disease are different. Crohn's disease is an inflammatory bowel disease of unknown cause, commonly occurring in the terminal ileum and right half of the colon. Small intestinal ulcers may be caused by intestinal inflammation and damage to the mucosa, making the ulcers easier to heal, whereas Crohn's disease tends to recur frequently and is not easily cured. Crohn's disease can also affect the joints, skin, liver, and other parts, and may be complicated by acute perforation, bloody stools, intra-abdominal abscesses, and malabsorption syndrome. It is advisable to consult a gastroenterologist and pay attention to adjusting the diet structure, eating meals regularly, and maintaining nutritional balance.
