Blood pressure is a measure of the force exerted against the walls of the arteries as the heart pumps blood through them. A blood pressure reading is composed of two different pressures—diastolic and systolic. Systolic pressure, as described by the National Heart Blood and Lung Institute, is the pressure exerted when the heart beats and pumps blood.

Diastolic pressure is the pressure while the heart is resting between beats. Low blood pressure occurs when either the diastolic or the systolic pressure is below normal. Three main types of low blood pressure cause noticeable symptoms that can be dangerous. Neutrally mediated hypotension (NMH) is low blood pressure that drops after standing for a long period or because of extreme emotional stress. Orthostatic hypotension is low blood pressure that occurs when rising from a sitting or lying down position. Severe hypotension is low blood pressure that can lead to shock, a potentially fatal condition in which blood pressure is so low that vital organs, such as the brain and kidneys, do not get sufficient blood to function properly.

You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries.

Dangerously Low Blood Pressure

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 the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them.

How To Raise Low Blood Pressure

In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes, or in extreme cases,.NIH: National Heart, Lung, and Blood Institute.
