 I am Dr. Vishwanath, consultant nephrologist and HOD nephrology. I am working at Manipal Hospital, Bangalore. Exercise though it does not help directly to prevent kidney disease, indirectly it will help in the form of controlling the blood pressure well, controlling the blood sugars well. Obesity also is a risk factor for further progression, so it will keep the weight under control so that it will prevent further progression of kidney disease. Exercise to some extent moderate will definitely help in the early stages. The late stages severe exercise may not be possible, in the early stages at least 20-30 minutes in a day, 5-6 days of a week, overall most of the forums recommend per week at least 150-180 minutes of exercise. Moderate exercise is good enough to control both blood pressure and blood sugar, indirectly this may help in preventing further progression of kidney disease.
