Low Blood Pressure (Hypotension): Overview
Low blood pressure, otherwise known as hypotension, is a condition characterized by abnormally low pressure in blood vessels. When blood pressure is too low, the supply of oxygen that is carried in the blood cannot be effectively distributed throughout the body.
Low blood pressure can be caused by many conditions including, but not limited to, bleeding, infections, dehydration, heart disease, adrenal deficiency, pregnancy, prolonged bed rest, poisoning, toxic shock syndrome, and blood transfusion reactions. Conditions of the nervous system can also cause low blood pressure including, but not limited to, fright, Shy-Drager Syndrome, Parkinson's Disease, and neuropathy. In addition, certain drugs may cause low blood pressure.
Persons experiencing low blood pressure may exhibit symptoms such as dizziness, light-headedness and fainting. Severely low blood pressure can cause shock.
