[|Human|] Hello Doctor, My father, who is 70 years old, has recently been diagnosed with slightly high urea and creatinine levels (urea 47 mg/dl and creatinine 1.5 mg/dl). We are from India. The doctor says there are no real medicines to control these directly and these have to be diet controlled primarily. I would like to know which foods to avoid in this scenario? Thanks.
[|AI|]  Hello, thanks for posting on Chat Doctor. The urea levels are slightly raised, and also his creatinine value is borderline high. Your doctor is right when he told you to control on diet. Creatinine and urea are by products of unused proteins in body. So, first thing to do is to limit intake of proteins to 1gm/kg/day which is requirement for human body. Anything more than that will be converted to urea, creatinine and other waste products. Secondly restrict intake of salt in diet. Daily intake should not be more than 3-4 gm /day. By doing this you will also keep decrease the risk of developing hypertension thus keeping kidneys healthy. Try avoiding high potassium diet like fruits like banana, Chat Doctor.  I think and hope the above given advice answers your query well, if you need more information you can always ask me. Thank you
