I had the lap band 5years ago, but lately I noticed some M&M like fat or oil bubbles in my stool. What could this be?
If this only happened when you may have eaten a small amount of sunflower oil or soybean oil when you are allergic to these, then it is unlikely that this is a fat malabsorption or a problem with your gallbladder.
sounds like fat malabsorbtion. Might be something with your gallbladder (reduced gall, no fat absorbtion). But loose stools, which float and leave films in a sign of fat malabsorbtion.
This is probably just a version of your diarrhea and I wouldn't worry about it unless it continues.
