Blood magnesium findings in osteoporosis.

Serum and erythrocyte Mg and Ca were examined in 60 patients with osteoporosis; 33 patients suffered from senile osteoporosis, 18 patients from postmenopausal and 9 from medicamentous osteoporosis. The biochemical signs of chronic magnesium deficiency were present in the first two groups due to lowering erythrocyte magnesium. The tendency to blood calcium disturbance was demonstrated in the third group.
