If you have orthostatic hypotension, your doctor may suggest that you try some simple ways to prevent symptoms like dizziness. For example, you can:
Stand up slowly.
Drink more water.
Drink little or no alcohol.
Limit or avoid caffeine.
Wear compression stockings.
If you feel dizzy or lightheaded, sit down or lie down for a few minutes. Or you can sit down and put your head between your knees. This will help your blood pressure go back to normal and help your symptoms go away.
