Elderly Blood Pressure Chart: Normal and High Blood Pressure by Age

Your blood pressure is the barometer of your overall circulatory health. Your circulatory system is made up of your heart and blood vessels, which carry oxygen and nutrients throughout your body. But did you know that over 70% of U.S. seniors have high blood pressure? Also called hypertension, high blood pressure is a major health risk that can lead to heart disease, stroke, and chronic kidney disease.

You can help your elderly loved one take an active role in lowering their blood pressure with simple lifestyle changes such as increasing physical activity and eating healthy, balanced meals. If your aging parent lives in an assisted living community, ask about exercise programs and meal options that are low in sodium. But if changes in lifestyle don’t help, prescription medications have proven very effective in lowering blood pressure.

What is a good blood pressure target for elders?

Blood pressure often rises with age, but experts agree that lower numbers are better for overall health. Blood pressure is measured in two numbers: systolic and diastolic. The top number is the systolic blood pressure, which measures the pressure caused by the heart contracting and squeezing out blood. The bottom number is diastolic blood pressure, which measures the pressure when the heart relaxes and fills with blood.

Elderly blood pressure range for men and women

Guidelines for blood pressure targets in older adults differ among medical organizations. The American College of Cardiology (ACC) and the American Heart Association (AHA) updated their guidelines in 2017 to recommend men and women who are 65 or older aim for a blood pressure lower than 130/80 mm Hg.

Blood pressure categories for adults 65+Systolic mm HgDiastolic mm Hg
Low blood pressure90 or lower60 or lower
Normal blood pressureLower than 120Lower than 80
Elevated blood pressure120-129Lower than 80
High blood pressure stage 1 (severe)130-13980-89
High blood pressure stage 2 (more severe)140 or higher90 or higher
High blood pressure crisis (see your doctor immediately)180 or higher120 or higher

Older adults whose blood pressure is elevated but lower than 130/80 mm Hg can help regulate their blood pressure through lifestyle changes such as increasing physical activity, eating a heart-healthy diet that’s low in salt, and limiting alcohol.

The updated ACC and AHA guidelines recommend that older adults with a blood pressure reading of 130/80 mm Hg or higher be treated with medication. As blood pressure continues to rise, seniors will enter stage 1 to indicate that hypertension is at a severe level. If numbers continue to increase, seniors will be in stage 2. If blood pressure continues to increase, seniors will be in a high blood pressure crisis. Previous recommendations set the threshold for high blood pressure treatment with medication for adults 65 or older at 150/80 mm Hg.

This change aims to reduce the risk of heart disease in older adults. However, your loved one’s doctor will assess their overall health and any other conditions before determining the best course of action to help your aging parent control their blood pressure.

Since blood pressure tends to increase with age, some medical societies argue about the effectiveness and safety of treating older adults for high blood pressure. Overall, older adults should aim for lower blood pressure numbers, but a blood pressure reading of 90/60 mm Hg or lower is considered too low (hypotension). Excessively low blood pressure may cause dizziness or fainting and increase the risk of falls.

Why does blood pressure increase with age?

Doctors don’t completely understand why blood pressure tends to rise with age. Blood pressure is the force of blood as it flows through the arteries. As you age, your arteries may narrow and become stiff. Narrow arteries lead to an increase in blood pressure. High blood pressure can damage the walls of the arteries and the heart itself.

In some cases, high blood pressure could be a result of lifestyle, the environment, certain medications, or other conditions such as sleep apnea, kidney disease, or thyroid problems.

What you should know about fluctuating blood pressure in the elderly

As you help monitor your loved one’s blood pressure, keep in mind that if numbers fluctuate slightly throughout the day, that’s normal. Several factors influence your blood pressure numbers. For example, your blood pressure may be lower if you’re resting and higher if you’re stressed. This means you may have a normal reading in the morning and an elevated number in the afternoon.

If you’re concerned about excessive fluctuation in your loved one’s blood pressure numbers, keep the following tips in mind:

  • Read the instructions to ensure you’re using your home blood pressure monitor equipment correctly. Variations in how you measure your loved one’s blood pressure can result in different readings.
  • Bring your home monitor to your next doctor’s appointment to compare readings.
  • Be aware of white coat hypertension. In some cases, a person’s blood pressure may be high at a doctor’s office but normal at home. This could be attributed to the stress related to a doctor’s appointment.

Your loved one’s doctor may want you to keep a blood pressure diary with several readings a day for a couple of weeks to monitor any variations.

How older adults can maintain a healthy blood pressure

Maintaining healthy blood pressure doesn’t have to be complicated. Simple lifestyle changes can help:

  • Exercise. National guidelines recommend adults of all ages engage in at least 150 minutes of moderate physical activity each week. If mobility or health conditions are a problem, older adults should try to be as physically active as possible.
  • Lose weight. If your loved one is overweight, every 2 pounds lost can help reduce blood pressure by 1 mm Hg.
  • Eat a heart-healthy diet low in salt. The DASH diet is rich in fruits, vegetables, whole grains, poultry, fish, and low-fat dairy foods. It was designed specifically to help lower blood pressure. Try to limit sodium to no more than 2,300 milligrams per day.
  • Avoid drinking alcohol. Alcohol can raise your blood pressure. If your loved one chooses to drink alcohol, limit it to no more than one drink a day for women and up to two drinks a day for men.
  • Don’t smoke. Tobacco damages your artery walls. If your loved one smokes, ask their doctor how to help them quit.
  • Manage stress. Try simple relaxation techniques, such as deep breathing exercises or meditation.

In some cases, diet and lifestyle changes aren’t enough to lower blood pressure. Your loved one may be having a difficult time achieving significant changes in their lifestyle, or their hypertension may be too severe to treat with diet and exercise alone.

Several types of medication are available to treat high blood pressure. Talk to your elderly loved one’s doctor about whether a combination of medication, diet, and lifestyle changes may help control their blood pressure.
