Constipation Home > Conditions That Can Lead to Constipation
Sometimes straining to have a bowel movement causes a small amount of intestinal lining to push out from the anal opening. This condition, known as rectal prolapse, may lead to secretion of mucus from the anus. In most cases, eliminating the cause of the prolapse, such as straining or coughing, is the only treatment necessary. Severe or chronic prolapse requires surgery to strengthen and tighten the anal sphincter muscle or to repair the prolapsed lining.
Constipation may also cause hard stool to pack the intestine and rectum so tightly that the normal pushing action of the colon is not enough to expel the stool. This condition, called fecal impaction, occurs most often in children and older adults. An impaction can be softened with mineral oil taken by mouth and by an enema. After softening the impaction, the doctor may break up and remove part of the hardened stool by inserting one or two fingers into the anus.
