Rectal prolapse is usually curable. Rectal prolapse is a disease in which the mucosal layer of the rectal wall or the whole layer of the intestinal wall is displaced downward, which refers to the situation in which a mass is prolapsed from the anus when the patient has a bowel movement or when the pressure in the abdominal cavity increases due to other reasons. Clinically, it is mainly categorized into rectal prolapse and rectal mucosal prolapse. Rectal prolapse is most common in children and the elderly. In children, rectal prolapse is usually self-healing within five years of age. Rectal prolapse in adults, especially the elderly, usually requires medication or surgery depending on the specific progress of the patient. Most rectal prolapse can be cured after active cooperation with the doctor. Therefore, when rectal prolapse is detected, it is recommended to go to the hospital as soon as possible for prompt treatment to avoid aggravation of the condition.
