Dear Sir,

My father is a diabetic. He is 62 years old. His sugar levels are usually controlled. Recently he was admitted in the hospital (he fainted, had breathing problem as he did not take his blood pressure medicine for 7 days while travelling). Doctor told he has kidney problem.

His urea and creatinine levels are high. Creatinine level is 5.7. doctor has advised a strict low potassium diet.

He was taking medicine for BP and sugar. Now the doctor has put him on insulin.

He used to walk 2-3 km every morning. But now he is too weak to exercise. Doctor says weakness is because of the controlled diet. However, now he has prescribed a multivitamin.

I would appreciate if you could suggest ways to recover kidney completely.
