Sir my father had hernia operation last february. After that he had water retention in legs and hands. Then his creatinine level and urea was also very high some doctors suggested to do dialysis. My father didnt accept to do dialysis. But now his whole body has been swelled and low sugar, he is always sleeping no intake of diet. is there any ways to reduce the water retention what would be the next step we shall follow. kindly give me a suggestion. thanks.
