High blood pressure, or hypertension, is a major health problem that is common in older adults. Your body’s network of blood vessels, known as the vascular system, changes with age. Arteries get stiffer, causing blood pressure to go up. This can be true even for people who have heart-healthy habits and feel just fine. High blood pressure, sometimes called "the silent killer," often does not cause signs of illness that you can see or feel. Though it affects nearly half of all adults, many may not even be aware they have it.

    If high blood pressure isn't controlled with lifestyle changes and medication, it can lead to serious health problems, including cardiovascular disease such as heart disease and stroke , vascular dementia , eye problems , and kidney disease . The good news is that blood pressure can be controlled in most people.

    What is blood pressure?

    Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood. When a health care professional measures your blood pressure, they use a blood pressure cuff around your arm that gradually tightens. The results are given in two numbers. The first number, called systolic blood pressure, is the pressure caused by your heart contracting and pushing out blood. The second number, called diastolic blood pressure, is the pressure when your heart relaxes and fills with blood.

    A blood pressure reading is given as the systolic blood pressure number over the diastolic blood pressure number. Blood pressure levels are classified based on those two numbers.

    • Low blood pressure , or hypotension, is systolic blood pressure lower than 90 or diastolic blood pressure lower than 60. If you have low blood pressure, you may feel lightheaded, weak, dizzy, or even faint. It can be caused by not getting enough fluids , blood loss, some medical conditions, or medications, including those prescribed for high blood pressure.
    • Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80.
    • Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.
    • High blood pressure is defined as 130 or higher for the first number, or 80 or higher for the second number.

    For older adults, often the first number (systolic) is 130 or higher, but the second number (diastolic) is less than 80. This problem is called isolated systolic hypertension and is due to age-related stiffening of the major arteries. It is the most common form of high blood pressure in older adults and can lead to serious health problems in addition to shortness of breath during light physical activity, lightheadedness upon standing too fast, and falls . 

    One reason to visit your doctor regularly is to have your blood pressure checked and, if needed, plan how to manage your blood pressure.

    Do I have high blood pressure?

    Anyone can have high blood pressure. Some medical conditions, such as metabolic syndrome, kidney disease, and thyroid problems, can cause high blood pressure. Some people have a greater chance of having it because of things they can't change. These are:

    • Age. The chance of having high blood pressure increases as you get older, especially isolated systolic hypertension.
    • Gender. Before age 55, men have a greater chance of having high blood pressure. Women are more likely to have high blood pressure after menopause .
    • Family history. High blood pressure tends to run in some families.
    • Race. African Americans are at increased risk for high blood pressure.

    High blood pressure often has no signs or symptoms, but routine checks of your blood pressure will help detect increasing levels. If your blood pressure reading is high at two or more check-ups, the doctor may also ask you to measure your blood pressure at home .

    There are important considerations for older adults in deciding whether to start treatment for high blood pressure if it is above 130/80, including other health conditions and overall fitness. Your doctor may work with you to find a blood pressure target that is best for your well-being and may suggest exercise , changes in your diet , and medications .

    How can I control my blood pressure?

    You can often lower your blood pressure by changing your day-to-day habits and by taking medication if needed. Treatment , especially if you have other medical conditions such as diabetes , requires ongoing evaluation and discussions with your doctor.

    Lifestyle changes you can make to help prevent and lower high blood pressure:

    • Aim for a healthy weight. Being overweight adds to your risk of high blood pressure. Ask your doctor if you need to lose weight. In general, to maintain a healthy weight , you need to burn the same number of calories as you eat and drink.
    • Exercise. Moderate activity, such as brisk walking or swimming, can lower high blood pressure. Set goals so you can exercise safely and work your way up to at least 150 minutes (2.5 hours) per week. Check with your doctor before starting an exercise plan if you have any health problems that are not being treated.
    • Eat a heart-healthy diet. A balanced diet of vegetables, fruits, grains, protein, dairy, and oils — such as the Dietary Approaches to Stop Hypertension ( DASH ) eating plan — can lower your blood pressure.
    • Cut down on salt. As you get older, the body and blood pressure become more sensitive to salt ( sodium ), which is added to many foods during processing or preparation. Limiting your amount of salt each day may help. DASH is a low-salt diet.
    • Drink less alcohol. Drinking alcohol can affect your blood pressure. For those who drink, men should not have more than two drinks a day and women no more than one a day to lower their risk of high blood pressure.
    • Don't smoke. Smoking increases your risk for high blood pressure, heart disease , stroke , and other health problems. If you smoke, quit . The health benefits of quitting can be seen at any age — you are never too old to quit.
    • Get a good night's sleep. Tell your doctor if you've been told you snore or sound like you stop breathing for moments when you sleep. This may be a sign of a problem called sleep apnea . Treating sleep apnea and getting a good night's sleep can help to lower blood pressure.
    • Manage stress. Coping with problems and reducing stress can help lower high blood pressure.

    In addition to recommending lifestyle changes, your doctor will likely prescribe medication to lower your blood pressure to a safe level. Isolated systolic hypertension, the most common form of high blood pressure in older adults, is treated in the same way as regular high blood pressure but may require more than one type of blood pressure medication. You may try several kinds or combinations of medications before finding a plan that works best for you. Medication can control your blood pressure, but it can't cure it. If your doctor starts you on medication for high blood pressure, you may need to take it long-term.

    Tips for taking blood pressure medication

    Untreated high blood pressure can increase your risk of serious health problems. If your doctor prescribes medication to lower your blood pressure, remember:

    • If you take blood pressure medication and your blood pressure goes down, it means medication and lifestyle changes are working. If another doctor asks if you have high blood pressure, the answer is, "Yes, but it is being treated."
    • Healthy lifestyle changes may help lower the dosage you need.
    • Get up slowly from a seated or lying position and stand for a bit before walking. This lets your blood pressure adjust before walking to prevent lightheadedness and falls .
    • Tell your doctor about all the drugs you take. Don't forget to mention over-the-counter drugs, including vitamins and supplements . They may affect your blood pressure. They also can change how well your blood pressure medication works.
    • Blood pressure medication should be taken at the same time each day as part of your daily routine. For example, take it in the morning with breakfast or in the evening before brushing your teeth. If you miss a dose, do not double the dose the next day.
    • Remember to refill your medication before you run out and bring it with you when traveling. It’s important to keep taking your medication unless your doctor tells you to stop.
    • Before having surgery, ask your doctor if you should take your blood pressure medication on the day of your operation.
