what does it mean when diastolic blood pressure is 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.

In patients with symptomatic low blood pressure, there often is a marked drop in blood pressure upon standing, and patients may even develop orthostatic symptoms. The heart rate often increases.

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.

What is low blood pressure? As a general guide, low blood pressure is a reading of 90/60 or less. However, it is not necessary for both your systolic and diastolic readings to be in this range for it to be considered low blood pressure.

Hypotension is the medical term for low blood pressure (less than 90/60). A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood.

Blood pressure is considered low when the measure for systolic over diastolic is under 90/60; this is known as hypotension. Some people naturally have low blood pressure, especially if they are very fit, and this is not a problem.

Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure.

When blood pressure is too low, not enough blood reaches all parts of the body. As a result, cells do not receive enough oxygen and nutrients, and waste products are not adequately removed.

Symptoms of isolated diastolic hypotension include tiredness, dizziness, and falls. Because low diastolic pressure decreases blood flow to your heart, you may also have chest pain (angina) or symptoms of heart failure.

Chronically low blood pressure is worrisome when it is accompanied by symptoms such as dizziness or fainting. This can be a sign of an underactive or overactive thyroid gland, poorly functioning adrenal glands, anemia, mild dehydration, a low heart rate, and other conditions.

Introduction. Orthostatic hypotension is the sudden drop in blood pressure when suddenly standing or changing position. It is defined as a fall in systolic (maximum) blood pressure of at least 20 mm Hg or diastolic (minimum) blood pressure of at least 10 mm Hg when a person assumes a standing position.

Elevated. This is when your systolic blood pressure is between 120-129 and your diastolic pressure is less than 80. Stage 1 high blood pressure. This is when your systolic pressure is between 130-139 or your diastolic pressure is between 80-89.

Low blood pressure, or hypotension, is blood pressure that has dropped below healthy levels. It can be caused by dehydration, certain medical conditions and medications, and surgery. It can cause dizziness, blurred vision, headache, and fainting.

Low blood pressure has many different causes including: Emotional stress, fear, insecurity or pain (the most common causes of fainting) Dehydration, which reduces blood volume. The body's reaction to heat, which is to shunt blood into the vessels of the skin, leading to dehydration.

Low (Narrow) Pulse Pressure In trauma, a low or narrow pulse pressure suggests significant blood loss (insufficient preload leading to reduced cardiac output). If the pulse pressure is extremely low, i.e. 25 mmHg or less, the cause may be low stroke volume, as in Congestive Heart Failure and/or cardiogenic shock.

Generally, if the blood pressure reading is under 90/60 mm Hg, it is abnormally low and is referred to as hypotension. Some adults regularly have blood pressure in the hypotensive range but have no symptoms and do not require treatment.

Low blood pressure means that your blood pressure is lower than normal. Another name for low blood pressure is hypotension (say "hy-poh-TEN-shun"). In most healthy adults, low blood pressure does not cause problems or symptoms.
