TORONTO — Doctors are warning of the possibility of a surge in cases of a debilitating nervous-system disorder that may be associated with long COVID.

Postural orthostatic tachycardia syndrome (POTS) is a form of dysautonomia, which is an umbrella term used to describe several medical conditions that cause the autonomic nervous system to malfunction. The autonomic nervous system controls the body’s “automatic” functions, such as heart rate, blood pressure, digestion, kidney function, and temperature control.

In cases of POTS, specifically, patients’ blood flow is affected and they can experience light-headedness, fainting, chest pains, shortness of breath, and an uncomfortable, rapid increase in heartbeat after standing up.
