Dysautonomia
The autonomic nervous system controls heart rate, blood pressure, digestion, temperature, and more. Dysautonomia is a broad term for when that system doesn't work the way it should. Postural Orthostatic Tachycardia Syndrome (POTS) is the most recognized form: an abnormal spike in heart rate upon standing that causes dizziness, fatigue, brain fog, and fainting. It is more common in women, frequently follows viral illness or physical trauma, and is often seenn alongside hEDS, ME/CFS, MCAS, and Long COVID.
