I have been referred to endo for suspected hypo parathyroidism dr done 3 blood tests over 4 months all concluded low cslcium vit d what will happen?

Low calcium ; vit D: You do not want the low calcium to continue as it could cause muscle twitching and possibly seizure. Low vit d has its side effects for bone and possibly for heart. It may well be that you have hypoparathyroidism. Your doc will probably give you vit d and calcium supplements as vit d increases calcium level. Treatment is usu with suppl including synthetic vit d preparations like calcitriol.
