What are the main signs and symptoms of postural orthostatic tachycardia syndrome?

    Last Updated: October 25, 2023

    Signs and symptoms are at their worst when attempting to stand up, during which people will experience an increase in heart rate with no blood pressure change. During these episodes, people often feel lightheaded, dizzy, and nausea. Symptoms usually improve when returning to a recumbent or supine position.

    People may also experience brain fog, gastrointestinal problems, and fatigue.[1]
