Several years ago i was diagnosed with a weak muscle in my rectum/anus. this gives me a problem. can anything be done to fix the weak muscle?

Weak anal sphincter: This depends on a couple of things. Where the weakness is secondary to disruption of the muscle (number one cause prior 4th degree episiotomy repair) or whether it is due to a pudendal nerve weakness (the nerve that innervates the muscle). The general answer of treatment options is divided between the two causes. A colon ; rectal surgeon can evaluate for you.
