<s>[INST] Hi. My mum is 56 and her kidneys don t work so well. She won t go on dialysis. Her urea is 200 and creatinine is 8.4. Her potassium is 5.4. She is active and energetic and does a moderate amount of manual work. Please suggest some tips to reduce urea creatinine and potassium. She does follow a diet. [/INST] Hello,She has to be on low protein diet, and to drink at least 2 liters of water per day. She can try taking diuretics like Furosemide. This will lower the potassium level.Hope I have answered your query. Let me know if I can assist you further.Regards </s>
