I also have severe constipation and looking forward to do surgery,. You can search colo-rectum surgeon in Maryland in google. Now, the laxatives is useless for me. Are you the same ? My relative resist me to do operation, now, I don't know how to do it.
Presently, I live in calgary, the doctor here not suggest me to do operation as to too much diaherra. Write me something about yours ?
