Hi doctor, my father is aged 55 and is suffering from diabetes for which he is taking hamdard diabeat and for thyroid he is taking thyronorm 75 mcg. He has got stroke (ischemic stroke) few months back and is recovering. But, he has also been diagnosed with high serum creatinine and blood urea levels. Creatinine was 3.39 in the recent report and blood urea level were 91.21 and blood urea nitrogen is 42.03. Please suggest me some ayurvedic or unani treatment and what type of food to avoid. Thanks a lot.
