How common is salt sensitivity?

“Salt sensitivity” refers to how much a person’s blood pressure changes in response to changes in dietary sodium. Estimates of salt sensitivity in the population vary from about 10 to 30 percent of people with normal blood pressure and more than 50 percent of people with hypertension. Salt sensitivity is thought to be related to genetic factors, kidney function, race, age, body mass, fitness level and potassium intake, so prevalence likely changes over time as populations age, become more overweight or obese and more sedentary, and move away from potassium-rich diets.
