Treating Syncope: Prevention

If you have been told that your fainting is not caused by a heart problem, you can help prevent fainting. And you can learn to respond to your body's warning signs.

If you feel faint, lie down for a while. Sit down and put your head between your knees if you can't lie down.

If You Feel Faint

• Know the warning signs of fainting: weakness, nausea, dimmed vision, sweating, lightheadedness, or a fast heartbeat.

• Don't ignore or fight any signs that you may faint.

• Lie down until you feel better. Your symptoms should go away in about 20 to 30 minutes.

Small Changes Make a Big Difference

• Sit near the aisle so you can leave if you feel faint.

• Get up slowly after you have been lying down.

• If prescribed, wear special stockings to keep blood from pooling in your legs.

• If directed, add salt to your food to raise your blood pressure. Don't skip meals.

• Don't stand for long. Shop when lines are short.

• Drink water often, especially when exercising during hot weather.
