Abstract

The effect of age on older hypertensive patient's blood pressure responseto increased sodium intake is well known. Salt sensitivity which doesincrease with age and the decrease in renal function limiting the ability ofaged kidney to excrete sodium load are major factors, responsible for risein blood pressure during Na consumption in the elderly.
