Normal Blood Pressure Range

What Causes Low Blood Pressure? Dr.Berg

A normal blood pressure reading indicates that the heart and blood vessels are not working too hard pushing blood and that the blood is not exerting too much pressure on the walls of the vessels, says Aseem Desai, M.D., a cardiologist at Providence Mission Hospital in Southern California. Recent data from the American Heart Association suggests the optimal normal reading for adults over 20 is lower than 120/80 mmHgVirani S, et al. Heart disease and stroke statistics 2021 update . American Heart Association Journal. 2021 143:e254-e743. .

Dr. Desai notes blood pressure can vary depending on a persons age, gender, race and ethnicity, but it should still fall within the general normal range. While numbers lower than 120/80 are generally considered normal, Dr. Desai adds, The target blood pressure for treatment varies depending on age and associated co-morbidities .

When it comes to race and ethnicity, Dr. Desai says certain groups have a higher rate of hypertension. Non-Hispanic Black people have a significantly higher rate of hypertension compared to non-Hispanic white people, and Hispanics and non-Hispanic Asians have lower rates than the first two, he says.

What Can You Do To Treat Low Blood Pressure

While there may be short-term solutions, how you treat low blood pressure ultimately depends on what is causing it, explains Eksteen. In the short-term, sitting or lying down, elevating the legs, drinking water and eating something salty can help to bring blood pressure back up. Long-term treatment will obviously depend on the reason for low blood pressure and will be need to be directed by a medical professional.

Changes to your diet may also help alleviate the symptoms of low blood pressure in certain instances. In some people, low blood pressure can be triggered after a meal when blood rushes to the gut, reducing the blood flow in the rest of the body’s circulation. Smaller, frequent meals can help here, says Eksteen.

Its important to have your blood pressure checked regularly, and should you have any concern regarding your blood pressure, give your doctor a call.

Heart Rate And Exercise

In discussions about high blood pressure, you will often see heart rate mentioned in relation to exercise. Your target heart rate is based on age and can help you monitor the intensity of your exercise.

  • If you measure your heart rate before, during and after physical activity, youll notice it will increase over the course of the exercise.
  • The greater the intensity of the exercise, the more your heart rate will increase.
  • When you stop exercising, your heart rate does not immediately return to your normal heart rate.
  • The more fit you are, the sooner your heart rate will return to normal.

Why Diastolic Pressure Is Important Too

The findings about low diastolic blood pressure are intriguing, and they make sense intuitively, Dr. Conlin says. Diastolic pressure is measured during the point in the heart cycle when blood flows into the coronary arteries that feed the heart. When those arteries are clogged with fatty deposits, blood pressure beyond the narrowed areas will drop as blood works its way through the narrowed channels. As a result, part of the heart muscle may not get enough blood. Starved for oxygen and nutrients, the heart may become weak and prone to damage.

When To See A Doctor

What is Low Blood Pressure and is it harmful?

If you have signs or symptoms of shock, seek emergency medical help.

If you have consistently low blood pressure readings but feel fine, your doctor will likely just monitor you during routine exams.

Even occasional dizziness or lightheadedness may be a relatively minor problem the result of mild dehydration from too much time in the sun or a hot tub, for example. Still, it’s important to see your doctor if you have signs or symptoms of low blood pressure because they can point to more-serious problems. It can be helpful to keep a record of your symptoms, when they occur and what you’re doing at the time.

Treatment Of Low Diastolic Blood Pressure

Treating isolated diastolic hypotension is more difficult than treating general hypotension. If youre taking an alpha-blocker, your doctor can change you to a different high blood pressure medication.

If you have isolated low diastolic pressure and youre not on blood pressure medication, the only option may be to see your doctor more frequently for checkups and to watch for symptoms of heart failure. Currently, there isnt any medication available to treat isolated diastolic hypotension.

Treatment of general hypotension depends on the cause.

Overtreatment of high blood pressure can be managed by adjusting or changing medications. The goal is to keep the diastolic blood pressure between 60 and 90 mm Hg. Your doctor may also change other medications that cause hypotension.

Dehydration can be treated with fluid replacement. In some cases, you may need medications that increase blood pressure.

What’s The Difference Between Blood Pressure And Pulse

While your blood pressure is the force of your blood moving through your blood vessels, your heart rate is the number of times your heart beats per minute.

    If low blood pressure isnt causing any symptoms or interfering with your daily routineand depending on the underlying causeyour doctor may decide to just keep an eye on your readings and ask you to be on alert for any warning signs, Dr. Mehta says.

    There are also a few things you can do on your own to prevent problems.

    1. Switch to mocktailsor good old H20. Remember, alcohol is dehydrating and can lead to a drop in blood pressure. Water is the preferred thirst quencher, since it helps increase blood volume.

    2. Order the spinach salad. Certain foods play a key role in keeping your blood pressure in a healthy range. Vitamins B12 and folate, for example, help your body produce enough red blood cells to prevent anemia.

    Leafy greens, avocados, beans, and oranges can help you meet your folate quota, according to the Academy of Nutrition and Dietetics. Chicken, eggs, fish, milk, yogurt, and meat are good sources of vitamin B12.

    3. Dont skip meals. In fact, consider divvying up your meals into four or five small ones spread throughout the day. This can help prevent your blood pressure from dropping sharply after you push away from the table.

    4. Uncross your legs. This can be a tough habit to break, but sitting with your legs crossed can hamper your blood flow. Its also good to start taking your sweet time when changing positionssitting to standing, lying to sitting, and so on.

    What Procedures And Tests Diagnose Low Blood Pressure

    In some people, particularly relatively healthy ones, symptoms of weakness, dizziness, and fainting raise the suspicion of low blood pressure. In others, an event often associated with low blood pressure, for example, a heart attack, has occurred to cause the symptoms.

    Measuring blood pressure in both the lying and standing positions usually is the first step in diagnosing low blood pressure. In patients with symptomatic low blood pressure, there often is a marked drop in blood pressure upon standing, and patients may even develop orthostatic symptoms. The heart rate often increases. The goal is to identify the cause of the low blood pressure. Sometimes the causes are readily apparent . At other times, the cause may be identified by testing:

    Low blood pressure may not be discussed as often as high blood pressure, but it should be addressed, as prolonged low blood pressure can negatively affect your organs.

    A certain amount of blood pressure is needed to maintain blood flow to the organs, says Dr. Wong. The blood supplies oxygen and nutrients to these organs. If the blood pressure is too low, an adequate blood supply cannot get to these organs.

    If left untreated, low blood pressure can increase your risk of fainting, heart attack and organ damage, adds Dr. Desai.

    What To Do If You Experience A Sudden Drop In Blood Pressure

    A single low blood pressure reading is no cause to be concerned unless you experience other symptoms.

    A sudden drop in blood pressure as little as a drop from 120 to 100 in your systolic number can be dangerous if it triggers dizziness and fainting. Such symptoms can be a sign of an underlying problem that may need medical attention.

    You should keep a record of your activities and when symptoms happen to discuss them with your doctor. If you experience any low blood pressure symptoms related to shock, you should seek immediate medical attention.

    When Does Low Blood Pressure Become Dangerous

    The big concern with being dizzy, feeling faint, or having blurred vision due to low blood pressure is that you could fall.

    Its all about gravity, Dr. Mehta explains. When youre standing, your head is on top, and the blood pools down to the legs. Elevating your legs brings the blood back to your core and brain.

    While youre resting, ask someone to bring you a glass of water, in case dehydration was the reason your blood pressure dropped.

    After you feel better, contact your physicians office, and let them know what happened, Dr. Mehta says.
