There is no such thing as how to treat irritable bowel syndrome clinically. Irritable bowel syndrome is often treated with lifestyle modification, medication such as pivoxyl bromide, loperamide, lactulose, and psychological and behavioral therapies. 1. General treatment: try to remove the factors contributing to the disease, instruct patients to establish good living habits and dietary structure, and avoid eating foods that trigger symptoms. Inform patients of the nature of irritable bowel syndrome to relieve their worries. 2. Drug treatment: If the patient has abdominal pain symptoms, scopolamine, pivacyl bromide and other antispasmodic drugs can be chosen. If there is diarrhea, you can choose loperamide, compound diphenoxylate tablets and other antidiarrheal drugs. If there is constipation, you can choose polyethylene glycol, lactulose and other diarrhea drugs, the specific use of medication should follow the doctor’s instructions. 3. Psychological and behavioral therapies: For patients who are not well treated with general treatment and medication, psychotherapy, hypnotherapy and biofeedback therapy can also be chosen as prescribed by the doctor. It is recommended that patients with irritable bowel syndrome go to the hospital in time, and choose the appropriate treatment plan according to the condition under the guidance of the doctor.
