Anyone who has had COVID-19 can get PoTS, whether initially they experienced mild or severe symptoms. However, there are certain signs which can increase your risk of developing PoTS post-COVID. These include a pre-COVID history of concussion, dizziness, lightheadedness, and palpitations. A faulty immune system that attacks your body’s tissues by mistake can also play a part in development of Postural Tachycardia Syndrome.
