Surgery: For patients whose long-term drug treatment is not obvious or seriously affects their normal life, they can be treated by surgery to improve the symptoms of constipation. 3. Other treatments: for patients with fecal impaction, clean enema can be used for treatment; for patients with severe defecation disorder constipation, biofeedback therapy can be used to improve the coordinated movement of muscle groups during defecation, increase the number of bowel movements and improve constipation. In addition, patients with constipation should also pay attention to a light diet, eat more fiber-containing foods, and develop the habit of regular defecation.
