Dizziness, lightheadedness, racing heart after COVID-19? It could be dysautonomia

from LONG COVID ESSENTIALS
a resources series by The Sick Times x Long COVID Justice

Many people with Long COVID develop a condition called dysautonomia, in which your autonomic functions (or things your body does by itself, like heart beating) are disturbed. There are many kinds of dysautonomia; one form seen commonly in Long COVID is called POTS, or “postural orthostatic tachycardia syndrome.”

POTS symptoms often include:

  • Racing heart
  • Dizziness, or feeling like you might faint
  • Headache
  • “Brain fog” or trouble thinking clearly
  • Chest pain


POTS can happen when your body doesn’t respond well to changing positions. The automatic bodily functions that are supposed to keep your circulation working properly aren’t quite doing their job, and your heart beats extra hard to try to make up for it.

Cardiologists or neurologists usually diagnose POTS using an active standing or NASA Lean test. These tests monitor what happens when you change position, to see if your heart beats too fast. This is best done by a professional to rule out other issues and ensure you don’t faint. If you don’t have a provider, find a friend (for safety) to help you do an at-home test.

There are some things you can do at home to help manage POTS:

Some will find they need additional relief. If so, doctors have used medication to help POTS patients, even though there are no medications officially approved for it in the US. You may want to ask your doctor about:

  • Beta blockers, which slow the heart rate
  • Fludrocortisone, which helps your body hang on to fluids
  • Midodrine, clonidine and pyridostigmine, which can help rebalance your autonomic nervous system in different ways
