Hi Muralidharan, Welcome to HealthcareMagic Forum.
Treatment for nephrotic syndrome
includes treating the underlying condition that is causing it and taking medications. Kindly have Patience, as it will take some time for complete recovery. See to it that she sticks to her treatment plan and take her for regular follow up. In addition to this, Reduce the amount of fat and cholesterol
in her diet. She should be eating Less Protein, Less Calcium and Less Salt diet. You can seek a help of a Dietitian for this.
I Wish her Very Good Health.
