The Complete Long COVID Handbook, Volume 2: Dysautonomia
By Dr. Robert Groysman, MD
A roadmap to one of Long COVID's most overlooked root causes.
Millions are living with lingering symptoms after COVID-debilitating fatigue, brain fog, dizziness, palpitations, gut issues, sleep problems, and strange neurological sensations. At the center of these struggles lies
dysautonomia
, a malfunction of the autonomic nervous system that controls heart rate, digestion, temperature, and more.
In this groundbreaking volume, Dr. Robert Groysman-board-certified anesthesiologist, pain medicine specialist, and pioneer in Long COVID care-explains how dysautonomia fuels persistent symptoms and, most importantly, how to treat it.
Inside, you'll discover:
Clear explanations
of how the autonomic nervous system works-and what happens when it's stuck in "fight or flight."
Practical tools
to recognize, test for, and monitor dysautonomia, including HRV and COMPASS-31.
Therapies that restore balance:
Stellate Ganglion Block (SGB)
Vagus Nerve Stimulation (tVNS)
Epipharyngeal Abrasive Therapy (EAT)
Medications, supplements, and breathing protocols
How stress, inflammation, and poor sleep
worsen symptoms-and strategies to reset the system.
Real patient stories
that highlight recovery, setbacks, and hope.
More than symptom management
Dr. Groysman connects dysautonomia to conditions such as
POTS, MCAS, ME/CFS, and neuropathies
, showing how these fit into the larger Long COVID puzzle. He translates complex science into clear, actionable steps patients can take to their doctors-without overwhelming jargon.
