I am online and happy to help you with your question today.
Is this from feces leaking out after a bowel movement? Or is it mucus, blood etc?
How long ago was your banding?
Are these formed feces (lumps and stuff) or liquid feces?
Ok. Well, it sounds like you have a decrease in the muscular tone of your anal sphincter.
This really requires an GI doctor to work up. It may be due to damage of the muscle itself, the nerves to the muscle or something blocking the sphincter from closing well. The list of possible causes is very, very long and the treatment depends on what is going on.
This, however, is not something you should have to continue to suffer with. Most issues can be helped..
Physiological tests can be done to evaluate your anorectal fuction, GI motility, innervattion and stool. Some time Ultrasound is done
