About Low Blood Pressure
The heart pumps a constant supply of blood around the body. The blood flows through different networks in the body, for example, arteries, veins and capillaries. Blood pressure is a measure of the force of the blood on the walls of the arteries as the blood flows through them.
Its measured in millimetres of mercury and recorded as two measurements:
- systolic pressure the pressure when your heart beats and squeezes blood into your arteries
- diastolic pressure the pressure when your heart rests between beats
For example, if your systolic blood pressure is 120mmHg and your diastolic blood pressure is 80mmHg, your blood pressure is 120 over 80, which is commonly written as 120/80.
Normal blood pressure is between 90/60 and 140/90. If you have a sustained reading of 140/90 or more, you have high blood pressure . This puts you at greater risk of developing serious health conditions, such as heart attack or stroke.
People with a blood pressure reading under 90/60 are usually regarded as having low blood pressure.

Side Effects Of High Blood Pressure
Dangers of untreated high blood pressure include stroke, heart attack, heart failure, vision loss, kidney failure, vascular dementia and sexual dysfunction, says Dr. Desai. Its one of the top risk factors for developing atrial fibrillation, which is the most common heart rhythm disorder worldwide and can lead to stroke, heart failure and reduced quality of life.
Normal Blood Pressure For Men And Women By Age
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 Are The Symptoms Of Low Blood Pressure
Low blood pressure often has no symptoms, but can sometimes mean that not enough blood is flowing to your brain or organs. This can cause symptoms such as:
- feeling dizzy, faint or light-headed
- feeling unsteady
- suddenly noticing your heartbeat
- fainting
If you have these symptoms, stop what youre doing and sit down or lie down in case you fall, and drink some water.
Speak to your doctor or nurse if you experience these symptoms. As well as being unpleasant, they could mean youre at risk of having a fall. They could also be a sign of another health problem.
When Is Low Blood Pressure Too Low Hypotension And More
Some people naturally have low blood pressure, known as hypotension. However, when high blood pressure suddenly becomes low blood pressure, it could be cause for concern.

Low blood pressure, or hypotension, may be a sign of good health and of a decreased risk of heart disease. But not always. At times, continually low blood pressure or a sudden drop in blood pressure can lead to worrisome symptoms and even serious health problems.

Tips For Avoiding Low Blood Pressure
Talk to your healthcare provider or a dietitian about healthy foods to include on your shopping list. There are ways you can modify daily behaviors that may help as well.
If you suspect you may have anemia, be sure to visit your healthcare provider for testing to pinpoint the type of anemia and the best treatment options.
Here are a few other changes you can make to your diet to help raise your blood pressure:
- Eat small meals more frequently. Large meals may cause more dramatic drops in blood pressure, as your body works harder to digest larger meals.
- Drink more water and limit alcohol. Dehydration lowers blood pressure.
In addition to altering your diet, you may also be able to raise your blood pressure by making these lifestyle changes:
- If you exercise outdoors in extreme heat, take frequent breaks and be sure to increase hydration efforts.
- Avoiding spending long amounts of time in saunas, hot tubs, and steam rooms which can cause dehydration.
- Change body positions slowly.
- Avoid prolonged bed rest.
- Wear compression stockings, which help blood move back upward from your legs and feet. You can purchase them online.

How Is Low Blood Pressure Treated
If your blood pressure is naturally low and isnt causing you any problems it probably wont need any treatment. If you have symptoms and your doctor or nurse feels that you would benefit from treatment, they will try to find the cause of your low blood pressure so that they can find the best way to treat it.
The treatments will vary depending on the cause.
- A change in medications. If your GP thinks that your blood pressure is caused by a medication youre taking they might want to try an alternative medication or a different dose.
- Hormone replacement. If your low blood pressure is caused by a change in certain hormones, for example if your adrenal glands have been damaged, you may be referred to a specialist called an endocrinologist. They might prescribe hormone replacement medication.
- Medicines to stimulate your nerves. If you have a neurological condition, you may be given medicines to stimulate the nerves.
- Medicines for low blood pressure. These medicines narrow your blood vessels or expand the volume of your blood to raise your blood pressure. These are very rarely needed, as the treatments listed above and the changes you can make for yourself are usually enough.

High Blood Pressure Symptoms
High blood pressure is known as the silent killer because it typically has no symptoms. In fact, most people dont even realize they have hypertension until their blood pressure is monitored.
Symptoms dont develop until the numbers get very high and organs get damaged, often irreversibly, says Dr. Desai.
If you have severe hypertension, you might notice the below symptoms, some of which were reported by patients in a study in the British Journal of General PracticeGoodhart A. Hypertension from the patients perspective. British Journal of General Practice. 2016 66:570. :

Heart Rate Vs Blood Pressure
Blood pressure measures the force that moves blood through your blood vessels while your heart rate is the number of times your heart beats per minute. They are both important health indicators, but they are measured independently and dont necessarily increase or decrease synchronously.
A temporary increase in heart rate, such as during exercise, is not considered problematic. In fact, your heart is expected to rise during a bout of activity and return to its resting rate afterward. And the more intense you work, the more you should expect your heart rate to rise during exercise. Your heart rate can safely double during activity so long as it returns to its resting rate relatively soon after you finish your workout.
Significant increases in blood pressure, on the other hand, are not normal and should be monitored and shared with your health care provider.

What Are The Symptoms
Many people with low blood pressure don’t have any symptoms.
Symptoms to watch for include:
- Feeling dizzy, light-headed, or faint.
- Feeling sick to your stomach or vomiting.
- Feeling more thirsty than usual.
- Having blurry vision.
- Breathing very fast.
If you have symptoms of low blood pressure, especially dizziness or fainting, call your doctor.
Watch for symptoms of low blood pressure. Tell your doctor when the symptoms happen so he or she can treat them.
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.

While you may have heard of hypertension or high blood pressure, suffering from low blood pressure can be as dangerous as well. An optimal blood pressure reading is less than 120mm Hg and above 80 mm Hg. The first number indicates the systolic pressure or the pressure in the arteries when the heart beats and fills with them with blood. The second number represents the diastolic pressure which is the pressure in the arteries when the heart rests between beats. Low blood pressure or hypotension may cause inadequate blood flow to the heart, brain, and other vital organs. A sudden drop in blood pressure often occurs when someone suddenly rises from a lying down or sitting position. This is called postural hypo-tension and may cause light-headedness and dizziness. There are some home remedies for low blood pressure that you can employ in order to deal with the symptoms of erratic blood pressure. But if youve been feeling the following symptoms for a while, consult your doctor and get your blood pressure measured
- Fatigue
- Loss of consciousness
- Blurry vision

Lifestyle Changes For Low Bp
Eat small meals frequently Consuming smaller and more frequent meals has been known to help with hypotension. This is because smaller and frequent meals reduce the gap between each meal and also keep you filled with the right nutrients, thereby reducing the chances of low blood pressure, as compared to larger and heavier meals.
Increase salt intake A sure shot low BP treatment at home is to increase your salt intake. Salt contains sodium and for people with blood pressure problems, higher sodium intake can be a good solution. Thus, consuming more salt can help raise your blood pressure.
Wear compression stockings The role of compression stockings is to decrease the amount of blood to be constricted to your lower legs and help it to be distributed throughout the body. They can also help to reduce the pressure and pain arising out of varicose veins. You can easily buy them for yourself online.
Dont get up or move around quickly Any sudden or rapid movements can cause problems for someone with low blood pressure. For example, sitting up or standing up quickly can make you feel lightheaded, dizzy, or can even cause you to faint.
Avoid alcohol Alcohol can cause your blood pressure to fall so if you already have low blood pressure, you should avoid any sort of alcoholic beverages.
Drink plenty of water Water helps increase the volume of blood as well as reduce any chances of dehydration. Both of these can help in increasing your blood pressure.
Normal Blood Pressure By Age Race And Gender
Previously, guidance for normal blood pressure for adults varied by gender and specific age, but new data states normal blood pressure for adults as a collective is less than 120/80 mmHgHigh Blood Pressure Symptoms and Causes. Centers for Disease Control and Prevention. Accessed 7/16/2021. .
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.
The reason for this variance can range from substandard insurance coverage and poor access to healthcare to gaps in the use of medications to treat multiple conditions with reduced compliance in certain groups, he adds.
As for gender, theres increasing evidence for risk of cardiovascular disease in women with blood pressures lower than what is considered normal, says Jennifer Wong, M.D., medical director of non-invasive cardiology at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, California.

Apple Cider Vinegar Drink
You may also want to try consuming a drink with apple cider vinegar to lower blood pressure.
A study published in the Bioscience, Biotechnology, and Biochemistry in 2001 found that the acetic acid from apple cider vinegar would significantly lower renin activity and blood pressure, compared to controls not given acetic acid or vinegar.
The enzyme renin is known to increase blood pressure from stretching receptors in the vascular walls.
Another study from 2006 showed that the acetic acid from apple cider vinegar would regulate high blood pressure by reducing high cholesterola common risk factor in hypertension.
You can take up to three tablespoons twice daily of apple cider vinegar in a glass of filtered water for blood pressure reduction. The key with apple cider vinegar is to start with a low dose and work your way up.
That being said, I recommend two tablespoons of apple cider vinegar in a drink, along with 12 ounces of warm water, two tablespoons of lemon juice, a teaspoon of honey, and a quarter-teaspoon of cinnamon.
What Can You Do To Help Relieve Symptoms Of Low Blood Pressure
Depending on the type of low blood pressure you have, you may be able to relieve some of your symptoms by:
- Eating a healthy diet with fewer carbohydrates and smaller meals.
- Drinking more water and avoiding alcohol.
- Getting up slowly after youve been sitting or lying down.
