Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Nephrotic syndrome is curable. But he might require long term treatment with steroids probably for one or two years. You can give him low salted food. Avoid nephrotoxic drugs. You have to check his blood pressure once in every month as there is a chance for hypertension in nephrotic syndrome patients. Hope I have answered your query. Let me know if I can assist you further.
