Decreased performance of the kidneys

Aging can increase the risk of decreasing kidneys function. In fact, kidney failure often occurs in the age of 65 or older.

As well we know, kidneys problem is the most common cause of secondary hypertension – as noted before. Secondary hypertension due to a kidneys disease is medically called as renal hypertension.


In renal hypertension, one or some of arteries that carry blood from heart to kidneys don’t work as well as it should. In many cases, the problem is caused by atherosclerosis or other conditions that narrow the diameter of an artery that connect between the heart and kidney.

If a kidney receives and gets too low volume of blood flow, it acts as if the problem is caused by dehydration. As a result, it then will stimulate certain hormones to respond the problem.

The released of these hormones can make your body retain more sodium and water! Eventually, your blood vessels will fill with more additional fluid and this can raise your blood pressure.

Lifestyle factors

Certain risk factors of hypertension associated with lifestyle factors tend to occur when you get older.

For instance, older adults and elderly people are more likely to become inactive if compared with young adults and teenagers. If you have lack of physical activity, you are easier to gain weight and get obesity that can be another risk factor of hypertension.

Uncontrolled stress is also pretty common in older adults – though there is still no strong scientific evidence to confirm the issue of increased risk of stress as we age.
