Thank you for your query on Healthcare Magic.
The treatment for rickets
is by giving Vitamin D injection.
After 4 weeks X-ray has to be taken to know the healing process.
If the healing is present child can be put on vitamin D and calcium supplementation to prevent rickets.
In X-ray, if there is no healing, then another dose of Vitamin D injection has to be given, still there is no response the other causes of Vitamin D resistant rickets has to be evaluated further.
Oral vitamin D also can be given in higher doses for 5 weeks to achieve the healing in alternate to injection.
You can give fortified diet.
Sun exposure is not effective in treating rickets.
Hope I have answered your query.
