Less salt intake eases high blood pressure
Dear Dr. Roach • I have type II diabetes and high blood pressure, which I generally keep below 130/80 with medication. My doctor is concerned about my salt intake. When I pointed out that my sodium level from a recent blood test was in the middle of the normal range, my doctor stated that that was something different. Can you explain why? — G.A.
Answer • Sodium levels in the blood are not affected by salt intake in people with normal kidneys and access to water. This is because sodium intake is balanced by increasing water intake, so the level of sodium in the blood stays tightly regulated. It’s why we get thirsty after having a salty meal.
