Hypotension (Low Blood Pressure)
When your systolic blood pressure is blow 80, it is known as hypotension (low Blood pressure)
Blood pressures below the norm are not considered to be a problem as long as the organs are getting enough blood and the kidneys are able to function. However, extremely low pressures-those in which the systolic pressure drops below 80-will usually result in symptoms such as dizziness or fainting. Extremely low pressures are often a result of trauma to the body and the cause must be identified and treated immediately. For example, excessive blood loss or severe dehydration will cause the blood pressure to plummet as low as 60/40. Once the blood or fluid is replaced, the pressure should begin to return to normal.
