Anal incontinence

Anal incontinence (AI), also known as fecal incontinence (FI), is a medical condition characterized by the inability to control the bowel movements, leading to an involuntary passage of stool. This condition can range from an occasional leakage of stool while passing gas to a complete loss of bowel control.

Causes

Anal incontinence can be caused by a variety of factors. These include damage to the anal sphincter muscles, damage to the nerves of the anal sphincter muscles or the rectum, loss of storage capacity in the rectum, diarrhea, and constipation. In some cases, it can also be caused by a medical procedure such as an anal sphincterotomy.

Symptoms

The primary symptom of anal incontinence is the inability to control bowel movements. This can lead to other symptoms such as skin irritation due to leakage of stool, social isolation due to embarrassment, and emotional distress.

Diagnosis

Diagnosis of anal incontinence involves a detailed medical history and physical examination. Additional tests may include anorectal manometry, anal electromyography, proctography, anal ultrasound, and magnetic resonance imaging (MRI).

Treatment

Treatment for anal incontinence depends on the cause and severity of the condition, and may involve lifestyle changes, medication, special exercises, or surgery.
