What are the symptoms of hypotension?

The signs and symptoms of hypotension are as follows:

Orthostatic hypotension
The signs and symptoms of orthostatic hypotension may happen within a few seconds or minutes of standing up after you've been sitting or lying down. You may feel that you're going to faint, or you may actually faint. Signs and symptoms include:

  • Dizziness or feeling lightheaded
  • Blurry vision
  • Confusion
  • Weakness
  • Nausea (feeling sick to your stomach

These signs and symptoms go away if you sit or lie down for a few minutes until your blood pressure adjusts to normal.

Neurally mediated hypotension
The signs and symptoms of neurally mediated hypotension (NMH) are similar to those of orthostatic hypotension. They occur after standing for a long time or in response to an unpleasant, upsetting, or scary experience. The drop in blood pressure with NMH doesn't last long and often goes away after sitting down.

Severe hypotension linked to shock
In shock, not enough blood flows to the major organs, including the brain. The early signs and symptoms of reduced blood flow to the brain include lightheadedness, sleepiness, and confusion. In the earliest stages of shock, it may be hard to detect any signs or symptoms. In older people, the first symptom may only be confusion.
