Not knowing more information, I'd recommend practicing your kegels faithfully! Gravity definitely has its effects.

Yes, I understood that. Truly, besides dietary changes and/or medicinal help to thicken up your stool and perhaps time (not sure how far out you are from surgery...), kegels are the best help. Not vaginal, of course! If you go up to the "Information" heading, the drop-down menu has a link for kegel exercises; click there and you will find detailed directions for practicing these effectively. They really can make a tremendous difference with anal control.

Good luck,

I get the same problem and what I have read on this site is that I may need an antispasm drug
