Irritable bowel syndrome is a common functional bowel disorder without organic pathology. There is no self-cure for irritable bowel syndrome in the past ten years, and its proper treatment includes dietary and lifestyle modification, symptomatic treatment with medication, and psychological and behavioral therapies. 1. Diet and life regulation: understand the factors that promote the development of the disease and try to remove them, establish good living habits and dietary structure, choose a diet that is easy to digest and low in fat, and prohibit stimulating and sensitive foods. 2. Symptomatic treatment with medication: when the patient’s symptoms are obvious, symptomatic medication can be used. Diarrhea can use montelukast, medicinal charcoal, loperamide to relieve symptoms. Constipation can be treated with laxatives, such as lactulose and polyethylene glycol, as well as prokinetic agents, such as mosapride and itopride. Abdominal pain can be applied with antispasmodics including pivobromine, cetropium bromide, and medications that modulate visceral sensations. 3. Psychological and behavioral therapy: the doctor should inform the patient of the nature of irritable bowel syndrome, relieve the patient’s concerns, so as to eliminate their fears and improve their confidence in overcoming the disease. If necessary, sedation, antidepressant treatment, psychotherapy, cognitive therapy can be used. If gastrointestinal discomfort occurs, you should go to the hospital in time, under the guidance of the doctor to carry out standardized treatment, to avoid serious adverse consequences. Drugs need to be used under the guidance of a professional physician, and should not be used arbitrarily on their own.
