My brother was diagnosed with hyperparathyroidism. any tips or suggestions for him?

Depends primary?: Primary disease, means unknown cause, needs surgery unless he is elderly. Will need lots of water unless has swelling or chf, to prevent kidney stones that form in this disease. Secondary disease, means due to kidney weakness, is treated by vit d, but you need to help by stopping phosphorus rich foods i.e. Dairy products, cola, chocolate, processed food. Root beer ok decrease legume beans.
