SALT FOR HEALTHY BLOOD PRESSURE: SALT SENSITIVES, BEWARE

Some people can eat a bag of salty pretzels and their blood pressure remains normal; for others, just thinking about salt wreaks havoc with their blood pressure. An estimated 20 to 30 percent of people with hypertension have a condition called salt sensitivity, which means they have a severely pronounced response to sodium. Sodium restriction is extremely important for these people, as they not only have four times the risk of developing hypertension compared with people who respond normally to salt, but even small amounts of sodium can trigger a dramatic rise in blood pressure. Researchers are still looking into the mystery of salt sensitivity. Who gets it? What causes the condition? Is there a gene responsible? Although many theories exist, we still don’t know for sure. Some of the possible mechanisms include kidney insufficiency, adrenal sensitivity to angiotensin, hereditary causes, or a sensitivity to the chloride fraction of salt (sodium chloride).
When I see patients who have been told they have resistant hypertension (abnormally high blood pressure that does not come down despite treatment with at least three drugs), I always suspect salt sensitivity. I have found that resistant hypertension can often – though not always – be remedied by strictly curtailing dietary sodium and supplementing with extra potassium. To find out if you are salt sensitive, check with your doctor or simply monitor your blood pressure response to dietary sodium changes. If you are sensitive to salt, you’ll need to severely curtail your sodium intake and increase your potassium consumption.
