what does it mean when your diastolic is very low?

If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen. That is what we call ischemia, and that kind of chronic, low-level ischemia may weaken the heart over time and potentially lead to heart failure.

The bottom number tells you what your blood pressure is when your heart is at rest between heartbeats. It is called diastolic pressure.

A normal diastolic blood pressure is lower than 80. But even if your diastolic number is lower than 80, you can have elevated blood pressure if the systolic reading is 120-129. 80-89 is stage 1 hypertension. 90 or more is stage 2 hypertension.

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.

Generally, low blood pressure during pregnancy isn't a cause for concern unless you experience symptoms. Big drops may be the sign of a serious, or even life-threatening, problem. Extremely low blood pressure can lead to falls, organ damage, or shock.

What's considered low? Current guidelines define a normal blood pressure reading as less than 120 mm Hg systolic (the top number) over 80 mm Hg diastolic (the bottom number). Doctors typically determine you have low blood pressure if your reading is below 90/60 mm Hg.

The bottom number refers to your blood pressure when your heart muscle is between beats. This is called diastolic pressure. Both numbers are important in determining the state of your heart health. Numbers greater than the ideal range indicate that your heart is working too hard to pump blood to the rest of your body.

Also called hypotension, low blood pressure is not a problem if you're healthy and show no signs or symptoms of the condition. However, abnormally low blood pressure can cause problems such as dizziness and fainting and can be a sign that other serious conditions, such as heart disease, are present.

Hypotension is blood pressure that is too low. This can happen in acute disease (where the illness comes on suddenly) or as a side-effect of some medicines. Some children with hypotension may have no symptoms, but some may experience: dizziness or light-headedness.

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.

Low blood pressure is a reading of less than 90/60mmHg. It does not always cause symptoms, but you may need treatment if it does.
394876
Low blood pressure that causes an inadequate flow of blood to the body's organs can cause strokes, heart attacks, and kidney failure. The most severe form is shock. Common causes of low blood pressure include a reduced volume of blood, heart disease, and medications.

If your blood pressure is lower than 90/60, you have low blood pressure, or hypotension. You may feel lightheaded, weak, dizzy, or even faint. Low blood pressure can be caused by not drinking enough liquids (dehydration), blood loss, some medical conditions, or too much medication.

Hypotension can be dangerous because it's a frequent cause of falls. Isolated diastolic hypotension can be especially dangerous because it can decrease blood flow to your heart. You may be at higher risk if you have coronary artery disease. Over time, isolated diastolic hypotension can cause heart failure.

What It Means If You Have Low Blood Pressure But a High Heart Rate. Low blood pressure coupled with a high heart rate is normal when it happens momentarily — like when we stand up — but long-term it could signal a heart rhythm problem.
847224
The amount of blood being pumped out of the heart is less than the body needs. A reduced ejection fraction can happen because the left ventricle is enlarged and cannot pump normally.

Low blood pressure (known as hypotension) is categorized if your reading is 90/60 mm Hg or lower. Low blood pressure in pregnancy is normal and is caused by the rapid expansion of the circulatory system.
