Whether a terminal ileal ulcer is serious or not depends on the specific situation and cannot be generalized. Symptoms of terminal ileal ulcers are not typical, and can be characterized by paroxysmal dull pain in the right lower abdomen with localized bloating and diarrhea, which often lasts for half an hour or an hour and can be relieved. Ulcers of the terminal ileum are more common in ulcerative colitis and Crohn’s disease, which are usually benign lesions that run in families and need to be treated with oral NSAIDs. However, if patients do not receive timely treatment, it may lead to intestinal obstruction, abdominal abscess, intestinal perforation, gastrointestinal bleeding, and even the possibility of cancer, which needs to be taken seriously. Therefore, when patients have abdominal discomfort or other abnormalities, they must go to the gastroenterology department to perform relevant examinations in time for clear diagnosis and timely treatment. In daily life, we should actively abandon bad eating habits, such as overeating, or regular consumption of spicy, stimulating, greasy food, etc. It is recommended to eat a light diet, eat more fruits and vegetables, and at the same time, work and rest regularly to ensure sufficient sleep.
