Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest). The greatest drop in blood pressure occurs at the transition from arteries to arterioles.
What is the lowest blood pressure you can live with?
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.
Is 100 too low for blood pressure?
Low blood pressure, or hypotension, is rarely cause for concern — unless it’s extremely low and related to shock. Hypotension is commonly defined as a blood pressure less than 100/60 (pressure between 100/60 and 120/80 is considered optimal). For most people, living with low blood pressure is not an issue.
Is blood pressure 90 50 too low?
Normal blood pressure for adults is generally in the range of 90/50 to 120/90 mm Hg . Hypotension is an abnormally low blood pressure, usually below 90/50 mm Hg. In severe or prolonged cases, it can be a serious medical condition.
Why do veins have the lowest blood pressure?
Arteries have thick walls so they can handle the high pressure and velocity that expels your blood out of your heart. Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries.
Is 80 40 blood pressure too low?
Low Blood Pressure: When to Seek Emergency Care. Your ideal blood pressure is between 90/60 mmHg and120/80 mmHg. If it gets too low, then you have low blood pressure, or hypotension. You could go into shock from lack of blood and oxygen to your vital organs.
What if your blood pressure is 70 over 40?
However, 70/40 is a rather low reading, and could definitely cause the need to sit down or feel a little lightheaded. Unusually low readings should be evaluated to rule out medical causes such as orthostatic hypotension, endocrine disorders, fainting, dehydration, severe infection and shock.
Is 110/60 too low blood pressure?
Normal blood pressure in adults is less than 120/80 mmHg. Low blood pressure is a reading below 90/60 mmHg. Most forms of hypotension happen because your body can’t bring blood pressure back to normal or can’t do it fast enough, says the National Heart, Lung and Blood Institute.
Is blood pressure 103 64 too low?
If your blood pressure is 120/80 millimeters of mercury (mm Hg) or lower, it’s considered normal. Generally, if the blood pressure reading is under 90/60 mm Hg, it is abnormally low and is referred to as hypotension.
What should I do if my blood pressure is too low?
Treatment
- Use more salt. Experts usually recommend limiting salt in your diet because sodium can raise blood pressure, sometimes dramatically. …
- Drink more water. Fluids increase blood volume and help prevent dehydration, both of which are important in treating hypotension.
- Wear compression stockings. …
- Medications.

Can you have a heart attack with low blood pressure?
Low blood pressure alone isn’t an indication of a heart attack, since not everyone will experience a decrease in blood pressure during a heart attack. In some people, a heart attack may not cause any significant changes in blood pressure at all.
When should I go to the ER for low blood pressure?
Low blood pressure is defined by a blood pressure reading of 90/60 mm Hg or lower, but a reading this low isn’t necessarily a cause for concern. It becomes a concern if you start to exhibit symptoms of dizziness, shortness of breath, or fainting; if this happens, you should seek medical attention.
What are the signs of low blood pressure?
Symptoms of low blood pressure
- Dizziness or lightheadedness.
- Nausea.
- Fainting (syncope)
- Dehydration and unusual thirst.
- Dehydration can sometimes cause blood pressure to drop. However, dehydration does not always cause low blood pressure. …
- Lack of concentration.
- Blurred vision.
- Cold, clammy, pale skin.

Where is blood pressure the highest?
Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
Does blood flow faster in arteries or veins?
Blood Flow
Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels. As the total cross-sectional area of the vessels increases, the velocity of flow decreases.
What is the normal BP range?
A normal blood pressure level is less than 120/80 mmHg. No matter your age, you can take steps each day to keep your blood pressure in a healthy range.
