SERUM eLRCTROLYTES AS TESTED ON 23.11.2012 ARE Na: 120; k: 5.2 Whether Electral concentration has to be increased. She is a Non Diabetic but on medication for hyper tension  <response>: Welcome yo Chat Doctor, and thanks for your query. Serum Sodium levels to increase needs water restriction than increased sodium intake. Water needs to be seriously restricted to 1 to 1.5 liters only for 24 hours including other Chat Doctor. If electoral contains potassium, it is wise to avoid as her SERUM K is already high.Also, renal function has to be monitored, as if the renal function is good, K should not go up. Kindly take an opinion from an internist nephrologist asap. Hope this helps your mother, Regards
