What a Sudden Drop in Blood Pressure Means
A sudden drop in blood pressure, also called hypotension, can occur for any number of reasons. It may be due to dehydration or simply rising from your chair too quickly, causing momentary dizziness and confusion.
But a sudden drop in blood pressure could also be a sign of a potentially serious condition like heart problems, heatstroke, or internal bleeding.
A sudden drop in blood pressure of just 20 mmHg, such as a change in systolic pressure from 100 mmHg to 80 mmHg could cause symptoms, and bigger drops could be related to a medical emergency.
Causes
There are many possible causes of hypotension.
Some can overlap, making the diagnosis difficult in some cases. The causes can be broadly categorized as the following:
- Hypovolemia: Describes reduced blood volume
- Decreased cardiac output: When the body is less able to pump blood due to an underlying condition
- Vasodilation: A sudden widening of blood vessels that causes blood pressure to drop
- Hypotensive syndrome: The term used when more than one factor causes a sudde
