Kindly tell me the treatment for vitamin D deficiency in a child.

Hello,

Welcome to icliniq.com.

Rickets can be due to vitamin D deficiency or hypophosphatemia. You did not tell me the phosphate level in blood of your child. The hypo-phosphatemic form of rickets is resistant to vitamin D supplement. As X-ray is normal, this is a remote possibility in your child. Alkaline phosphatase is very commonly found to be high in growing child. But it is also high in rickets. With treatment, ALP (alkaline phosphatase) comes to within reference range. I suggest you continue with the Vitamin D and Calcium supplementation and get a phosphate level in your child's blood. Do not worry if minor deformities are present. Because these deformities will disappear as the child grows. But if the child cannot walk properly despite having a normal X-ray, and normal phosphate level, then consult with an orthopedic consultant. He will help your child by suggesting some good orthoses. I suggest you do a repeat PTH (parathyroid hormone) test and to do a serum phosphate level. Also, continue the Calcium and Vitamin D supplementation. I hope this helps. Thank you and take care. Regards.
