Jul 31, · 10 Ways to Raise Low Blood Pressure. 1. Drink plenty of water. 2. Eat a balanced diet. 3. Eat smaller meals. 4. Limit or avoid alcohol. 5. Eat more salt. Mar 26, · Without prescription medicine, there are two primary approaches to raising low blood pressure: increasing blood volume or promoting vasoconstriction. To simplify, adding fluids and electrolytes to your body can increase your blood volume, while taking certain herbs or other substances can cause your blood vessels to constrict, which raises blood pressure.
Low blood pressure might seem desirable, and for some people, it causes no problems. However, for many people, abnormally low blood pressure hypotension can cause dizziness and fainting. In severe cases, low blood pressure can be life-threatening. A blood pressure reading lower than 90 millimeters of mercury mm Hg for the top number systolic or 60 mm Hg for the bottom number diastolic is generally considered low blood pressure.
The causes of low blood pressure can range from dehydration to serious medical disorders. It's important to find out what's causing your low blood pressure so that it can be treated. For some people, low blood pressure signals an what are the 3 largest rivers in the world problem, especially when it drops suddenly or is accompanied by signs and symptoms such as:.
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 what is a third sector organisation uk to what is a capital expense a record of your symptoms, when they occur and what you're doing at the time.
Blood pressure is a measurement of the pressure in your arteries during the active and resting phases of each heartbeat. What's considered low blood pressure for you may be normal for someone else. Most doctors consider blood pressure too low only if it causes symptoms. Some experts define low blood pressure as readings lower than 90 mm Hg systolic or 60 mm Hg diastolic.
If either number is below that, your pressure is lower than normal. A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg — a drop from systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting when the brain fails to receive enough blood. And big drops, such as those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening. Doctors often break down low blood pressure hypotension into categories, depending on the causes and other factors.
Some types of low blood pressure include:. Low blood pressure on standing up orthostatic or postural hypotension. This is a sudden drop in blood pressure when you stand up from a sitting position or after lying down. Gravity causes blood to pool in your legs when you stand. Ordinarily, your body compensates by increasing your heart rate and constricting blood vessels, thereby ensuring that enough blood returns to your brain. But in people with orthostatic hypotension, this compensating mechanism fails and blood pressure falls, leading to dizziness, lightheadedness, blurred vision and even fainting.
Orthostatic hypotension can occur for various reasons, including dehydration, prolonged bed rest, pregnancy, diabetes, heart problems, burns, excessive heat, large varicose veins and certain neurological disorders.
A number of medications also can cause orthostatic hypotension, particularly drugs used to treat high blood pressure — diuretics, beta blockers, calcium channel blockers and angiotensin-converting enzyme ACE inhibitors — as well as antidepressants and drugs used to treat Parkinson's disease and erectile dysfunction. Orthostatic hypotension is especially common in older adults, but it also affects young, otherwise healthy people who stand up suddenly after sitting with their legs crossed for long periods or after squatting for a time.
Low blood pressure after eating postprandial hypotension. This drop in blood pressure occurs one to two hours after eating and affects mostly older adults. Blood flows to your digestive tract after you eat.
Ordinarily, your body increases your heart rate and constricts certain blood vessels to help maintain normal blood pressure. But in some people these mechanisms fail, leading to dizziness, faintness and falls. Postprandial hypotension is more likely to affect people with high blood pressure or autonomic nervous system disorders such as Parkinson's disease.
Eating small, low-carbohydrate meals; drinking more water; and avoiding alcohol might help reduce symptoms. Low blood pressure hypotension can occur in anyone, though blood pressure is too low how to raise it types of low blood pressure are more common depending on your age or other factors:.
Even moderate forms of low blood pressure can cause dizziness, weakness, fainting and a risk of injury from falls. And severely low blood pressure can deprive your body of enough oxygen to carry out its functions, leading to damage to your heart and brain. Mayo Clinic does not endorse companies or products.

Nov 14, · Cross Legs While Sitting. Sitting cross legs can increase the blood pressure and this prove to be helpful with people suffering from hypotension. This is another good way to raise your blood pressure if it is too low. Low blood pressure is considered a problem if the symptoms are present, otherwise, it is considered a sign of good health.
You begin by lying flat on a table. Straps are put around your body to hold you in place. After lying flat for a while, the table is tilted to raise your body and head — simulating a change in position from lying down to standing up. During this test, your heart rate and blood pressure are monitored to evaluate your body's cardiovascular response to the change in position.
The goal in testing for low blood pressure is to find the cause. Besides taking your medical history, doing a physical exam and measuring your blood pressure, your doctor might recommend the following:. Electrocardiogram ECG. During this painless, noninvasive test, soft, sticky patches electrodes are attached to the skin of your chest, arms and legs. The patches detect your heart's electrical signals while a machine records them on graph paper or displays them on a screen.
An ECG , which can be performed in your doctor's office, detects irregularities in your heart rhythm, structural problems in your heart, and problems with the supply of blood and oxygen to your heart muscle. It can also tell if you're having a heart attack or have had one in the past. Tilt table test. If you have low blood pressure on standing or from faulty brain signals neurally mediated hypotension , a tilt table test can evaluate how your body reacts to changes in position.
During the test, you lie on a table that's tilted to raise the upper part of your body, which simulates the movement from horizontal to a standing position. Compression stockings, also called support stockings, compress your legs, promoting circulation. A stocking butler may help you put on the stockings.
Low blood pressure that either doesn't cause signs or symptoms or causes only mild symptoms rarely requires treatment. If you have symptoms, treatment depends on the cause. For instance, when medication causes low blood pressure, treatment usually involves changing or stopping the medication or lowering the dose.
If it's not clear what's causing low blood pressure or no treatment exists, the goal is to raise your blood pressure and reduce signs and symptoms. 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. For people with low blood pressure, that can be a good thing.
But because excess sodium can lead to heart failure, especially in older adults, it's important to check with your doctor before increasing the salt in your diet.
Wear compression stockings. The elastic stockings commonly used to relieve the pain and swelling of varicose veins can help reduce the pooling of blood in your legs. Several medications can be used to treat low blood pressure that occurs when you stand up orthostatic hypotension. For example, the drug fludrocortisone, which boosts your blood volume, is often used to treat this form of low blood pressure.
Doctors often use the drug midodrine Orvaten to raise standing blood pressure levels in people with chronic orthostatic hypotension.
It works by restricting the ability of your blood vessels to expand, which raises blood pressure. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition. Depending on the reason for your low blood pressure, you might be able to reduce or prevent symptoms.
Pay attention to your body positions. Gently move from a prone or squatting to a standing position. Don't sit with your legs crossed. If you begin to get symptoms while standing, cross your thighs in a scissors fashion and squeeze, or put one foot on a ledge or chair and lean as far forward as possible.
These moves encourage blood flow from your legs to your heart. Eat small, low-carb meals. To help prevent blood pressure from dropping sharply after meals, eat small portions several times a day and limit high-carbohydrate foods such as potatoes, rice, pasta and bread. Your doctor also might recommend drinking one or two strong cups of caffeinated coffee or tea with breakfast.
Don't drink caffeine throughout the day because you will become less sensitive to caffeine, and caffeine can cause dehydration. No special preparations are necessary to have your blood pressure checked. Don't stop taking medications you think might affect your blood pressure without your doctor's advice.
