What is POTS syndrome?

Postural orthostatic tachycardia syndrome (POTS) is a condition that causes lightheadedness, dizziness, and fainting when you stand up. This is because your blood pressure drops and your heart rate increases when you stand up, which can cause your brain to receive less blood.

POTS is more common in women than men, and it typically develops in people between the ages of 15 and 50. The exact cause of POTS is unknown, but it is thought to be related to a problem with the autonomic nervous system, which controls your body's involuntary functions.

Symptoms of POTS can include:

* Lightheadedness

* Dizziness

* Fainting

* Rapid heart rate

* Palpitations

* Chest pain

* Shortness of breath

* Fatigue

* Weakness

* Nausea

* Blurred vision

* Headaches

POTS can be diagnosed with a tilt table test, which measures your blood pressure and heart rate while you are lying down and then standing up. Treatment for POTS may include lifestyle changes, such as increasing your fluid intake, eating small meals, and avoiding alcohol and caffeine. Medications may also be prescribed to help control your symptoms.
