Thanks for your answer. Can you suggest some more exercise

Ans: The best way to strengthen any part or organ of the body is to appropriately challenge it with moderate amounts of stress and to then give it time to recover. You put stress on the muscles by lifting weights at the gym and they grow stronger when you take time to recover. Same concept would apply to the heart - you would challenge it with appropriate and moderate amounts of stress with cardio-vasuclar activity and then give it enough time to recover. Sun Salutations and Vinyasa styles of Yoga would be suitable for that. These should be supported by regular Pranayama practices like Box Breathing and mindfulness practices like meditation and Shavasana. Alternatively, you can consult a fitness trainer for other fitness activities suitable for your specific body type and needs.

Ans: Dear Mr Anil. I am a Nephrologist and deals with the kidney. You have 3 risk factors which can affect the kidneys; 1. Obesity, 2. Hypertension, 3. Pre-diabetes.
Definitely you need to reduce your weight. Otherwise it might affect the kidneys in the future.
Have a screening for kidney disease: Do simple tests like creatinine and urine routine, which will give you an idea about your kidney health.
If kidneys are fine, you can increase the protein intake and reduce the carbohydrate intake along with the exercise so that you can reduce your weight.
Please consult a dietitian and make a proper diet plan.
