Abnormally low blood pressure
Meaning: Abnormally low blood pressure. Classified under: Nouns denoting stable states of affairs. Hypernyms (hypotension is a kind of...): cardiovascular disease (a disease of the heart or blood vessels). Hyponyms (each of the following is a kind of hypotension): orthostatic hypotension; postural hypotension (low blood pressure occurring in some people when they stand up). Antonym: hypertension (a common disorder in which blood pressure remains abnormally high (a reading of 140/90 mm Hg or greater)). 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. In fact, it may be normal for you. For example, people who exercise regularly often have lower blood pressure than people who are not as fit. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. 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. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats. 1 Low blood pressure, also called hypotension, is blood pressure low enough that the flow of blood to the organs of the body is inadequate and symptoms and/or signs of low blood flow develop shock. 2  Low pressure alone, without symptoms or signs, usually is not unhealthy. 1 These symptoms are most prominent when individuals go from the lying or sitting position to the standing position (orthostatic hypotension). 2  Low blood pressure that causes an inadequate flow of blood to the body's organs can cause strokes, heart attacks, and kidney failure. Many people worry about low blood pressure (hypotension), but probably don't need to. Some people have a blood pressure level that is lower than normal. In general this may be good news-because the lower your blood pressure is, the lower your risk of stroke or heart disease. However, in a few cases, having low blood pressure can cause problems, so you might need to speak to your doctor or nurse Mildly low blood pressure, or hypotension, may be a sign of good health and a decreased risk of heart disease, but in some people, hypotension can be a problem. At times, continually low blood pressure or a sudden drop in blood pressure can lead to worrisome symptoms and even serious health problems.  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. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats. 1 A number of drugs can cause low blood pressure, including diuretics and other drugs that treat hypertension; heart medications such as beta blockers; drugs for Parkinson's disease; tricyclic antidepressants; erectile dysfunction drugs, particularly in combination with nitroglycerine; narcotics and alcohol.  Postural hypotension is the most common type of low blood pressure. In this condition, symptoms appear after a person sits up or stands quickly. In normal people, the cardiovascular system must make a quick adjustment to raise blood pressure slightly to account for the change in position.  Hypotension is the medical term for low blood pressure (less than 90/60). Normal blood pressure is usually in the range of 120/80 (systolic/diastolic). In healthy people, especially athletes, low blood pressure is a sign of good cardiovascular (heart and blood vessel) health.
