Why Blood Pressure Rises With Age
8089 -- 11/5/99
Blood pressure often rises with aging. Contrary to what many doctors think, salt, obesity and alcohol
have little to do with this rise.
High blood pressure is associated with heart attacks, strokes, aging and death. Recent research shows
that high blood pressure associated with aging is probably caused by damage to the arteries leading to
the kidneys. Obesity, excess salt and alcohol cause reversible high blood pressure. Taking a large
amount of salt can cause your body to retain fluid, enlarge blood volume and raise blood pressure
temporarily, but blood pressure returns to normal soon afterwards. For most people, taking in a lot of
salt does not raise blood pressure. Drinking alcohol raises blood pressure only for a short time. Obesity
is associated with a sustained high blood pressure at any age, and is usually reversible with weight loss.
Recent research show that damaged kidney arteries, called intimal fibroplasia, are the most likely cause
of high blood pressure and that prevention of high blood pressure with aging includes preventing kidney
arterial damage by eating plenty of fruits, vegetables, whole grains, beans and nuts, reducing your intake
of processed foods and dairy products, exercising and avoiding overweight.
