Which meds are you taking?
This white balls were reported after taking Metformin.
It could be clumps of bacteria or candida. In this case you'd be BLOATED.
I have a similar problem. My pills also don't dissolve and none of the medications I take work at all. I had an upper GI endoscopy, and a stool culture and everything came back negative. I don't know what to do because my health is deteriorating as a result of my inability to absorb pills.
