With the amount of calcium we need to take after bypass I'm curious to know if there's and correlation with increased chance of kidney stones or breast calcifications or anything else?

I am not sure but if we don't take calcium the risk of developing osteoporosis is much more debilitating. My mother has it and as we age the bones don't fuse together well after a fracture. Basically your frame can't hold you up properly. I will take stones over what she has gone through: multiple fractures, crushed vertebrates, pins to support bones fractures and hip replacements. Once you lose bone mass you can't get it back. I know kidney stones can be painful but the alternative is much, much worse.
