After bm, i'm having bowel leakage especially if i sit on buttock or run. i can't also control passing gas. can pelvic floor exercise be helpful?

Maybe yes...: Occasional incontinence of stool with fecal leakage is common, but loss of bowel control particularly without warning may signal a significant infection, inflammatory problem, maldigestive concern, or neurologic disorder. Sometimes, particularly in youths, the condition is behavioral. Often, anal manometry followed by biofeedback can be curative without the need of surgery or medication.
