What Is Considered Low Blood Pressure Reading?

Overview

Some possible symptoms of depression claret pressure.

What is depression claret pressure?

Hypotension, or low claret force per unit area, is when your blood pressure is much lower than expected. It can happen either as a condition on its own or as a symptom of a broad range of conditions. It may not cause symptoms, but when it does, it can crave medical attention.

Hypotension has two definitions:

• Absolute hypotension: Your resting claret force per unit area is below 90/60 mmHg (millimeters of mercury).
• Orthostatic hypotension: Your claret pressure drops within iii minutes of y'all continuing up from a sitting position. The drop must exist 20 mmHg or more for your systolic (top) pressure and x mmHg or more for your diastolic (bottom) pressure. Another name for this is postural hypotension because it happens with changes in posture.

Measuring blood pressure involves ii numbers, top and bottom, in mm/Hg.

• Systolic (top number): Your systolic pressure is the force per unit area on your arteries each fourth dimension your center beats. To find your systolic force per unit area, a healthcare provider* inflates a cuff that squeezes your arm. At the same time, they listen to your pulse at a point below the cuff. Your systolic pressure is when they can't hear your pulse anymore because the cuff's pressure is stronger than the pressure from your heart pumping.
• Diastolic (lesser number): That number is how much pressure your arteries are nether between heartbeats. The provider will keep listening for your pulse to discover your diastolic pressure while they deflate the gage. Your diastolic pressure is the number where they can again hear your heartbeat as the gage deflates.

*Thanks to technological advances, many modernistic devices can measure out your blood pressure automatically. These devices are now recommended for use instead of measuring blood pressure with the traditional stethoscope method.

What is the difference betwixt hypotension vs. hypertension?

Hypotension and hypertension are reverse conditions.

• Hypertension: The prefix "hyper-" means "too loftier."
• Hypotension: The prefix "hypo-" means "too low."

Who does information technology affect?

Hypotension can affect people of whatever age and background, depending on why information technology happens. Withal, it's more likely to cause symptoms in older people (especially orthostatic hypotension). Information technology tin can too happen with no symptoms to people who are very physically agile, which is more than common in younger people.

How common is this status?

Considering low blood pressure is mutual without any symptoms, it'southward incommunicable to know how many people it really affects overall. However, orthostatic hypertension seems to be more than and more mutual as you get older. An estimated 5% of people have it at age 50, while that figure climbs to more 30% in people over 70.

How does this condition touch my body?

Under normal circumstances, your torso can automatically control your blood pressure and keep it from dropping too much. If information technology starts to driblet, your body tries to recoup for that, either past speeding up your heart rate or constricting claret vessels to make them narrower. Symptoms of hypotension happen when your body can't compensate enough to offset the drib in blood pressure.

For many people, hypotension doesn't cause any symptoms. Many people don't even know their blood pressure level is low unless they get their blood pressure level measured.

For people with symptoms, the effects depend on why hypotension is happening, how fast information technology develops and what caused information technology. Slow decreases in claret pressure happen normally, so hypotension becomes more common as people get older. Fast decreases in blood pressure level can mean certain parts of your torso aren't getting enough blood flow. That tin take effects that are unpleasant, disruptive or even unsafe.

Symptoms and Causes

What are the symptoms?

What causes low blood pressure?

Hypotension can happen for a broad range of reasons.

• Orthostatic hypotension. This happens when you stand too chop-chop and your body can't compensate with more blood menstruation to your brain.
• Central nervous system diseases. Conditions similar Parkinson's affliction tin can impact how your nervous system controls your claret pressure. People who have hypotension because of these conditions may feel the effects of low blood pressure subsequently eating because their digestive system uses more than claret as it works to digest food.
• Low blood book. Claret loss from severe injuries can cause low claret pressure. Dehydration tin can also contribute to low claret volume.
• Life-threatening conditions. These weather condition include irregular heart rhythms (arrhythmias), pulmonary embolism, heart attacks and complanate lung. Life-threatening allergic reactions (anaphylaxis) or immune reactions to astringent infections (sepsis) tin can also cause hypotension.
• Middle and lung conditions. When your centre beats too fast or too slow, or if your lungs aren't working as they should, both can lead to hypotension.
• Prescription medications. Hypotension can happen with medications that treat blood pressure, eye failure, erectile dysfunction, neurological problems, depression and more.
• Alcohol or recreational drugs. Recreational drugs can lower your claret pressure level, equally can alcohol (alcohol's outcome only lasts a short time, and long-term overuse of booze tin cause high blood pressure). Though not technically medications, sure herbal supplements, vitamins or home remedies tin also lower your claret force per unit area, which is why you should always include these when you tell your healthcare provider what medications you're taking.
• Orthostatic hypotension is possible in the first and second trimesters of pregnancy. Haemorrhage or other complications of pregnancy can also cause low blood pressure.
• Extreme temperatures. Beingness too hot or also cold tin can affect hypotension and make its effects worse.

Is hypotension contagious?

No, hypotension isn't contagious, and so you can't get it from someone else or pass it to others.

Diagnosis and Tests

How is it diagnosed?

Hypotension itself is like shooting fish in a barrel to diagnose. All it takes is taking your blood force per unit area. Nevertheless, figuring out why you take hypotension is another story. If you have symptoms, a healthcare provider volition likely utilize a variety of tests to figure out why it's happening and if there's whatever danger to you because of it.

What tests will be done to diagnose this condition?

Treating hypotension unremarkably starts with finding out why it'southward happening. If that crusade is treatable directly, hypotension will usually become amend on its own.

• Making blood vessels constrict. Just every bit at that place are medications that lower your blood pressure past relaxing blood vessels in your body, there are also medications that take the opposite effect.
• Alter how your torso handles fluids. Your kidneys are responsible for maintaining the fluid balance in your body. Certain medications tin make your kidneys keep fluid and salt in your trunk, which tin can assistance with low blood pressure.

• Heart bug or stroke. Low blood force per unit area can cause your heart to try to compensate by pumping faster or harder. Over fourth dimension, that can cause permanent center harm and even heart failure. Information technology can besides cause problems like deep vein thrombosis and stroke because claret isn't flowing like it should, causing clots to form.
