It occurred to me after your suggestion of possible lack of pancreatic enzymes that my lovely gall stone has been moving around on me lately. Also I have Crohns in my duodernum (spelling)?
Now my hypothesis is this. The migrating stone which likes to block my duct on occasion could be the cause of the lack of pancreatic enzymes being pumped through my duodernum (spelling again) and into the stomach causing improper digestion and foamy stools. (Or) it could be yet another side effect rearing it's head from the Imuran/Humira/Predinose cocktails. Any takers on this one! Where the heck is Sarita! Any ho.....thanks for the info!
