Symptoms include chronic constipation. There can be fecal incontinence and paradoxical or overflow diarrhea (encopresis) as liquid stool passes around the obstruction. Complications may include necrosis and ulcers of the rectal tissue. Abdominal pain and bloating could also be present depending on the severity of the condition. Loss of appetite can also occur.
[edit]Treatment
The treatment of fecal impaction requires both the remedy of the impaction and treatment to prevent future recurrences. Decreased motility of the colon results in dry, hard stools that in the case of fecal impaction become compacted into a large, hard mass of stool that can not be expelled from the rectum.
Various methods of treatment attempt to remove the impaction by softening the stool, lubricating the stool, or breaking it into pieces small enough for removal. Enemas and osmotic laxatives can be used to soften the stool by increasing the water content until it is soft enough to be expelled. Osmotic laxatives such as magnesium citrate works within minutes - 8 hours for onset of action, and even then they may not be sufficient to expel the stool.
