Hypotension Health Dictionary

Insufficient pressure to propel contents of the circulatory vessels throughout the body. Persistent low blood pressure is usually the result of blood loss following accident, infection, anaemic disorders or shock from heart attack. Blood pressure is naturally low during sleep.

Causes: failure of the adrenal glands, tuberculosis, neurasthenia, psychological shock, constitutional debility. Blood pressure is consistently below 110mmHg. Myocardial infarction. Fainting attack. Symptoms. Dizziness, headache, fatigue, fainting, ringing in the ears, feels low, panicky, unable to concentrate, neurotic impulses, anxiety.

Alternatives. Underlying cause must be treated. Rest, tonics, good food, sunshine. When due to shock, hospital treatment may be necessary. Tonics and adrenal stimulants assist in raising pressure. Rosemary of special value. Hypotensives and antidepressant should not be given.

See: BLOOD PRESSURE. 

The medical term for low blood pressure. In its most common form, known as postural hypotension, symptoms occur after abruptly standing or sitting up. Normally, blood pressure increases slightly with changes in posture; in people with postural hypotension, this normal increase fails to occur. Postural hypotension may be a side effect of antidepressant drugs or antihypertensive drugs. It may also occur in people with diabetes mellitus. Acute hypotension is a feature of shock, and may be caused by serious injury or a disease such as myocardial infarction or adrenal failure. Treatment depends on the cause. In the absence of serious disease, low blood pressure is associated with decreased risk from cardiovascular disorders and stroke. Symptomless hypotension does not require treatment.

A fall in blood pressure below the normal level

Low blood pressure. Not always a bad thing unless you need 11 hours of sleep or faint if you stand too quickly.

Low blood pressure (see HYPERTENSION for raised blood pressure). Some healthy individuals with a normal cardiovascular system have a permanently low arterial blood pressure for their age. What blood-pressure reading constitutes hypotension is arguable, but a healthy young person with ?gures below 100 mm Hg systolic and 65 mm Hg diastolic could be described as hypotensive. For a healthy 60 year old, comparative ?gures might be 120/80. The most common type of hypotension is called postural, with symptoms occurring when a person suddenly stands up, particularly after a period of rest or a hot bath. It results from the muscular tone of blood vessels becoming relaxed and being unable to respond quickly enough to the changing posture, the consequence being a temporary shortage of arterial blood to the brain and organs in the chest. Symptoms of dizziness, occasionally fainting, and nausea occur. Older people are especially vulnerable and may fall as a result of the sudden hypotension. Some drugs – anti-hypertensives and antidepressant ones – cause hypotension. People with DIABETES MELLITUS occasionally develop hypotension because of nerve damage that affects the re?ex impulses controlling blood pressure. Any severe injury or burn that results in serious loss of blood or body ?uid will cause hypotension and SHOCK. Myocardial infarction (see HEART, DISEASES OF) or failure of the ADRENAL GLANDS can cause hypotension and shock. A severe emotional event that causes shock may also result in hypotension and fainting.

Hypotension in healthy people does not require treatment, although affected individuals should be advised not to stand up suddenly or get out of a bath quickly. Someone who faints as a result of a hypotensive incident should be laid down for a few minutes to allow the circulation to return to normal. Hypotension resulting from burns, blood loss, heart attack or adrenal failure (shock) requires medical attention for the causative condition.

Low blood pressure - usually with the diastolic (the lower level) below 60 mm Hg., and sufficient to cause symptoms (eg. dizziness/collapse).

n. a condition in which the arterial *blood pressure is abnormally low, which is most commonly experienced when rising from a sitting or lying position (postural or orthostatic hypotension). Severe cases may manifest as *shock.

low blood pressure, or a fall in blood pressure below the normal range.
