If a stool becomes lodged in the rectum (impacted), mucus and fluid
will sometimes leak out around the stool, leading to leakage of stool from the
anus (fecal incontinence).
If you have
hemorrhoids, small amounts of liquid stool or mucus
may leak out through the anus. Inflamed hemorrhoidal tissue can be swollen or
painful, making it difficult to clean yourself completely after having a bowel
movement. Stool remaining on the hemorrhoidal tissues may soil your underwear
or clothing.
Fecal incontinence is often caused by
rectal prolapse. It is also sometimes caused by
irritable bowel syndrome and
inflammatory bowel disease. If you have one of these
conditions, the need to pass stool can come on so quickly and urgently that
some stool may leak out before you can get to the bathroom.
Fecal incontinence can also be caused by a
stroke, a spinal cord injury or compression, or tumors
that involve the spinal cord. If you have suddenly lost the ability to control
your bowels, especially if you have any other signs of nerve damage, such as
numbness or weakness in the legs, call your health professional immediately to
discuss these symptoms.
