what is the lower number on your blood pressure?
13474
Blood pressure is recorded with 2 numbers. The systolic pressure (higher number) is the force at which your heart pumps blood around your body. The diastolic pressure (lower number) is the resistance to the blood flow in the blood vessels. They're both measured in millimetres of mercury (mmHg).

Normal blood pressure: Lower than 120/80 mmHg. Elevated blood pressure: Between 120-129/80 mmHg.

Normal blood pressure is usually considered 120/80 mm Hg or less. It is not treated with medicines generally until after it gets to 140/90 mm Hg or more. This is because there is no conclusive evidence that the benefits outweigh the risks of treating with medicines to blood pressure lower than 140/90 mm Hg.

Here is how to make sense of your numbers: Normal blood pressure: According to the American Heart Association, blood pressure is in the normal range if it's below 120/80 mm Hg. Prehypertension: Between 120/80 mm Hg and 139/89 mm Hg. Stage 1 high blood pressure: Between 140/90 mm Hg and 159/99 mm Hg.

The bottom number is the diastolic blood pressure, which is the force as your heart relaxes. These are the standard classifications for normal and high blood pressure. Normal blood pressure: 90/60 to under 120/80 mm Hg. Prehypertension, or risk for hypertension: 120-139/80-89 mm Hg.

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

if your top number is 140 or more - then you may have high blood pressure, regardless of your bottom number. if your bottom number is 90 or more - then you may have high blood pressure, regardless your top number. if your top number is 90 or less - then you may have low blood pressure, regardless of your bottom number.

More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it. Make healthy changes to your lifestyle.

Well, now you can appreciate the complexities of hypertension, or high blood pressure - a systolic pressure of 140 mmHg or more or a diastolic pressure of 90 mmHg or more - and hypotension, which is low blood pressure - a systolic pressure of 90 mmHg or less or a diastolic pressure of 60 mmHg or less.

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.

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.
1093932
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.

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.

Ranges. The National Institutes of Health cite normal blood pressure to be below 120 mm Hg systolic and 80 mm Hg diastolic.

Low blood pressure is also known as hypotension. People with a reading of around 90/60, or less, are commonly regarded as having low blood pressure. Some people who have low blood pressure experience symptoms as a result of it.

Blood pressure readings optimal – less than 120 / less than 80. normal – 120 to 129 / 80 to 84. high–normal – 130 to 139 / 85 to 89. high blood pressure – greater than 140/90.

Doctors generally define low blood pressure as 90/60 mm Hg or below, commonly said as “90 over 60” Usually, doctors only treat hypotension if it is severe enough to cause symptoms.
