Effect of hypocalcaemia on glucose tolerance, insulin release and free fatty acid levels in human subjects.

Eight patients with hypocalcaemia who presented with frank or latent tetany due to parathyroid insufficiency or nutritional osteomalacia were studied. Their serum calcium ranged from 6·85 to 7·7 mg/100 ml (mean 7·33±0·36 mg/100 ml). In six of them, serum calcium after treatment varied from 8·4 to 9·2 mg/100 ml.
