Orthostatic hypotension is low blood pressure that occurs when a person stands up from a seated or reclining position. For this reason, the condition is also called postural hypotension. Often, orthostatic hypotension is mild and short-lived. Sometimes, the person will be able to identify the reason their blood pressure has dropped and act accordingly to treat the problem at home. However, regular episodes of orthostatic hypotension could be a sign of an underlying health condition.
The most common symptom of orthostatic hypotension is a dizzy or light-headed sensation upon rising from sitting or lying down. The person may feel temporarily confused and have blurred vision. It can also cause nausea. Sometimes, the condition can cause weakness. If blood pressure becomes very low, the person may faint. Symptoms of orthostatic hypotension are temporary and usually last for just a few minutes.
