Enema can relieve constipation, but it is not recommended for patients to do it by themselves at home. Enema treatment is through the infusion of a certain amount of liquid, stimulate intestinal peristalsis, can help the patient smooth defecation, so as to relieve the symptoms of constipation or abdominal distension. Clinically, enemas are generally only taken when patients with persistent constipation have an urge to pass stools, or even abdominal pain and bloating, but are unable to pass stools. Prolonged enema will affect the normal bowel reflex, aggravate constipation, resulting in the inability to have a normal bowel movement without enema. Long-term enemas may also destroy the normal intestinal flora, affect the body’s water-electrolyte balance, and cause intestinal damage or anal relaxation. Self-operated enemas are even more risky, and may cause localized damage to the anus, resulting in infection or triggering complications such as intestinal perforation. Constipation patients are advised to regulate diet, drink more water, etc., and actively seek medical advice, under the guidance of the doctor to use Keserol or oral pills, etc., do not recommend self-diagnosis and treatment and self-operated enema.
