Thank you for your query,
is due to loss of protein in the urine which is manifested by swelling of the body, decreased urine output.
In most of the cildren , nephrotic syndrome is due to minimal change disease
and it responds to steroids
But in some there are relapses in nephrotic syndrome after discontinuing steroids and some may be steroid dependant and some patients may be steroid resistant.
Be in regular follow up with your Pediatrician
and give medication as per the doctor advise and prompt response may be expected in your child as per the age.
Hope I have answered your query.
