What can cause low blood pressure?

Answer 1

There are many causes for low blood pressure, ranging from excellent physical condition to insufficient blood volume. If you are otherwise feeling fine (not faint or weak, plenty of energy, etc.), I wouldn't worry about it. However, if you find yourself becoming nauseous, faint-headed or passing out, you should speak to a medical professional about this.

Answer 2

Blood pressure is the force of the blood against the artery walls. High blood pressure (hypertension) and low blood pressure (hypotension) can both cause cardiovascular problems. Ambulatory blood pressure monitoring or tilt table tests may be used to diagnose these conditions. There are many types of high blood pressure, which may be treated with antihypertensive medications, such as diuretics, beta blockers and ACE inhibitors.

Low blood pressure (hypotension) is pressure so low it causes symptoms or signs due to the low flow of blood through the arteries and veins. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney, the organs do not function normally and may be permanently damaged.

Unlike high blood pressure, low blood pressure is defined primarily by signs and symptoms of low blood flow and not by a specific blood pressure number. Some individuals may have a blood pressure of 90/50 with no symptoms of low blood pressure and therefore do not have low blood pressure. However, others who normally have high blood pressure may develop symptoms of low blood pressure if their blood pressure drops to 100/60.
