Hospitals in New Delhi

Hi!

Could someone recommend good hospitals in New Delhi? I would like to do a health check up and treatment, if necessary.

I am mainly interested in the hospitals specializing at endocrinology, gastroenterology, osteoporosis and blood vessels.

I read that private hospitals are quite commercialized while the government hospitals are poor in facilities; what would still be the preference in terms of health care quality?

Thank you!

wher u from?
