i am a HT/DM/CAD patient ;undergone bypass surgery in 2000; i have been prescribed with medicines for all the above and am taking regularly ; the HT and DM are well under control;during a normal test of blood recently itwas noticed that my blood urea is 37 , serum creatinine is 1.5 and potasium is 5.6; what does this indicate
A creatinine of 1.5 indicates a kidney function of less than 50%. (because creatine does not rise till 50% function is lost). Most likely it is due to DM and HTN. But it is good to do an ultrasound to check if there is no other problems. Get your urine checked for protein. Some of you heart medications may cause a mild rise in creatinine which is OK. You may need to restrict your salt and fluid (equal to your urine output) else it may put excess load on your heart. Avoid Chat Doctor.  Green vegetables are high in potassium - boil them for 15 mins and discard the water before preparations. Get a nephrologist to assess you in detail.
