Hi and thanks for the query.
I am Dr. Alok and very pleased to be assisting you with your health questions today.
I am so sorry to hear that you are suffering from all these problems. for
kidney heart disease, you need to take medicine prescribed to you.
Avoid unnecessary medicine especially pain killers or over the counter medicine with advice from your doctor, as they may affect your kidneys.
Limit your salt and fluid intake, you can discuss with your dietician.
Do regular exercise and keep your busy with some work and keep positive attitude.
Both diseases are not completely curable but well treatable and you can live normal life.
for indepth information, you need to see various websites for patients like emedicine etc
Hope this helps and provides answers to your question.
I wish you good health.
Dr. Alok
