Low blood pressure, or hypotension, occurs when blood pressure during and after each heart beat is much lower than usual. This means the heart, brain, and other parts of the body do not get enough blood. Dizziness or lightheadedness can result. See also: Blood pressure
|
|
Hypotension is the medical term for low blood pressure. The pressure of the blood in the arteries rises and falls as the heart and muscles handle demands of daily living, such as exercise , sleep and stress .
|
|
Doctors often consider chronically low blood pressure too low only if it drops suddenly or causes noticeable symptoms.
|
|
While recommended healthy blood pressure levels have decreased, lowering diastolic pressure too much could deprive the heart of needed blood flow, which could be dangerous for people with coronary artery disease.
