I had fecal incontinence supposedly due to dyssynergic sphincter. I had biofeedback therapy which didn't help. I then worked with a medical dietician, recommended by my gastroenterologist. Through diet (especially an increase in fiber and switching to low fodmap foods), Metamucil daily(3 tsps), and a low dose of magnesium citrate (150mgs. daily) it cleared up completely. I am now working, with the help of the same dietician to reduce and/or eliminate the mag citrate and just rely on an increased fiber intake. So far that is working well and I do not have the awful fecal leakage.
