What Can I Do To Prevent Or Manage High Blood Pressure

Why is Your Blood Pressure Low?

Many people with high blood pressure can lower their blood pressure into a healthy range or keep their numbers in a healthy range by making lifestyle changes. Talk with your health care team about

  • Getting at least 150 minutes of physical activity each week
  • Not smoking
  • Managing stress

In addition to making positive lifestyle changes, some people with high blood pressure need to take medicine to manage their blood pressure. Learn more about medicines for high blood pressure.

Talk with your health care team right away if you think you have high blood pressure or if youve been told you have high blood pressure but do not have it under control.

Changing The Body’s Position

Blood pressure can vary throughout the body due to the direct action of gravity. When a person is standing, blood pressure is higher in the legs than in the head, much in the way that the water pressure at the bottom of a swimming pool is higher than that at the top. When a person lies down, blood pressure tends to be more equal throughout the body.

When a person stands up, blood from the veins in the legs has a harder time getting back to the heart. As a result, the heart has less blood to pump out, and blood pressure may temporarily drop throughout the body. When a person sits down or lies down, blood can more easily return to the heart, and cardiac output and blood pressure may increase. Elevating the legs above the level of the heart can increase return of blood to the heart, which increases cardiac output and raises blood pressure.

When Blood Pressure Is Too Low

Whether blood pressure is too low has more to do with how you feel than the measured number. A blood pressure of 90/60 mmHG may be normal for someone young and healthy, but may cause symptoms of lightheadedness or weakness in an older patient or someone with other health conditions, Dr. Courson says.

Treatment For Low Blood Pressure

Having low blood pressure is not always an immediate cause for concern. Many people with low blood pressure are unaware that they have it. Doctors may only consider treatment for low blood pressure if it causes troubling symptoms.

People who experience temporary symptoms of low blood pressure, such as lightheadedness or increased heart rate after standing up too quickly, should sit down to rest until the symptoms subside.

People who frequently experience these symptoms must take great care when moving from a prone position to standing to avoid falling.

If a medication causes symptoms of low blood pressure, doctors may recommend switching medications or lowering a dosage. A person should only change their medication under the guidance of a doctor.

The note that some people may not need treatment for low blood pressure at all. However, for those that do, possible treatments may include:

  • drinking water to avoid dehydration
  • taking medications to raise the blood pressure
  • changing eating habits

Diastolic Blood Pressure: How Low Is Too Low

Heart Health
  • May 17, 2015

Blood pressure consists of two numbers. Systolic pressure, the force exerted on blood vessels when the heart beats, is the upper number. Diastolic pressure, the force exerted when the heart is at rest, is on the bottom in more ways than one. Systolic pressure attracts the lions share of attention from physicians and patients, says UAB cardiologist Jason Guichard, M.D., Ph.D.

Physicians are busy people, and like it or not they often focus on a single number, Guichard said. Systolic blood pressure is the focus, and diastolic pressure is almost completely ignored. That is a mistake, he argues. The majority of your arteries feed your organs during systole. But your coronary arteries are different they are surrounding the aortic valve, so they get blood only when the aortic valve closes and that happens in diastole.

Diastolic pressure has been getting more attention lately, however, thanks in part to an influential paper in Hypertension, written in 2011 by Guichard and Ali Ahmed, M.D., then a professor of medicine in UABs Division of Gerontology, Geriatrics and Palliative Care and now the associate chief of staff for Health and Aging at the Veterans Affairs Medical Center in Washington, D.C.

Most people are trying to lower their blood pressure. What would you define as too low, and why is that a problem?

Should I Be Concerned About Having High Blood Pressure And A Low Pulse

If youre taking blood pressure medication and have slightly high blood pressure and a low pulse, this generally isnt anything to be concerned about.

But if youre not taking any medication, its best to work with a doctor to figure out whats going on. This is especially true if you have symptoms of a low pulse, such as dizziness or shortness of breath.

The typical range of 60 to 100 beats per minute is both the average pulse measurement as well as the rate at which most peoples heart needs to beat to pump enough blood through their body.

Some people may simply have a lower pulse. Examples include athletes or those in very good shape. Theyve conditioned their heart muscle to be stronger. As a result, their heart pumps more effectively, meaning it doesnt need to beat as often. Learn more about why athletes have lower pulses.

Exercising can also temporarily raise your blood pressure. So, if you exercise regularly, you may have a naturally low pulse and higher blood pressure right after you work out.

How Do You Know If Your Blood Pressure Is Low

Most doctors will only consider chronically low blood pressure as dangerous if it causes noticeable signs and symptoms, such as:

  • Dizziness or lightheadedness.
  • Dehydration can sometimes cause blood pressure to drop.
  • Lack of concentration.
  • Blurred vision.
  • Besides, how do you raise your blood pressure if its too low?

    Depending on your age, health and the type of low blood pressure you have, you can do this in several ways:

  • Use more salt. Experts usually recommend limiting salt in your diet because sodium can raise blood pressure, sometimes dramatically.
  • Drink more water.
  • Medications.
  • What causes your blood pressure to drop?

    A sudden drop in blood pressure, also called hypotension, can occur for any number of reasons. Some may be of no real concern, while others may be a sign of a potentially life-threatening condition.

    This article will cover the various causes of low blood pressure, possible symptoms, and treatment options.

    Is Low Blood Pressure A Problem

    For some people, low blood pressure is a sign of good health. These are generally people who are very fit and who have a slow pulse. For other people, low blood pressure is a problem.

    Often, people with low blood pressure can be expected to lead longer lives.

    However, people who experience continuing symptoms of low blood pressure should see a doctor. Sudden, severe low blood pressure can be associated with serious medical conditions.

    Heart Tissue Damage And Heart Disease

    Researchers have found a link between low diastolic blood pressure and heart damage.A 2016 study that lasted more than 3 decades and involved more than 11,000 people found that a diastolic blood pressure below 60 mm Hg is dangerous.People with this level are 50 percent more likely to have heart damage. This is compared with those who have a low diastolic pressure level between 80 and 89 mm Hg.Heart disease is another concern. The same study found that those with low diastolic blood pressure were 49 percent more likely to develop heart disease.

    Why Low Blood Pressure Happens

    Fertig says there are two fundamental reasons why low blood pressure occurs. “First, the heart does not pump blood adequately to the organs and tissues of the body. This may or may not be due to heart disease,” he says. “Second, inadequate blood flow may be due to over dilated blood vessels from such causes as severe bacterial infection and adrenal gland or thyroid hormonal insufficiencies.”

    A Reaction To Medication

    Causes Of Low Blood Pressure

    An adverse reaction to prescribed or over-the-counter medicine can drop blood pressure unexpectedly. Diuretics and other drugs designed to treat hypertension, some anti-depressants, and medication to help with erectile dysfunction can lower blood pressure to unsafe levels. You can also experience a drop in blood pressure if you combine high blood pressure medications with others.

    Changing The Diameter Of Arterioles And Veins

    Muscle tissue within the walls of arterioles allow these blood vessels to widen or narrow . The more constricted arterioles are, the greater their resistance to blood flow and the higher the blood pressure. Constriction of arterioles increases blood pressure because more pressure is needed to force blood through the narrower space. Conversely, dilation of arterioles reduces resistance to blood flow, thus reducing blood pressure. The degree to which arterioles are constricted or dilated is affected by

    Veins also play a role in the control of blood pressure, although their effect on blood pressure is much less than that of arterioles. Veins dilate and constrict to change how much blood they can hold . When veins constrict, their capacity to hold blood is reduced, allowing more blood to return to the heart from which it is pumped into the arteries. As a result, blood pressure increases. Conversely, when veins dilate, their capacity to hold blood is increased, allowing less blood to return to the heart. As a result, blood pressure decreases.

    When To Worry About Low Blood Pressure

    We all know that high blood pressure can be dangerous. But what about low blood pressure

    Also called hypotension, low blood pressure is not a problem if youre healthy and show no signs or symptoms of the condition. However, abnormally low blood pressure can cause problems such as dizziness and fainting and can be a sign that other serious conditions, such as heart disease, are present.

    Medicines and lifestyle changes can help you live safely with chronic low blood pressure.

    Avoid alcohol. Alcoholic beverages are dehydrating, and alcohol changes how medicines work in your body.

    Slow down. Take your time when standing up. If lying down, sit up first. Then wiggle your feet and move your legs. This will increase circulation and get your heart rate up so that you dont feel lightheaded when you stand up.

    If your medicine and lifestyle changes do not reduce your low blood pressure symptoms, talk with your doctor about other changes you can make.

    • Knowing your actual, average blood pressure outside of regular fluctuations
    • Gaining more control over your blood pressure
    • Tracking your progress
    • Saving time and possibly money from frequent doctor visits and complications
