POTS Update 2026: What the Latest Research Gets Right and Misses

POTS is not one condition with one cause and treating the elevated heart rate alone often fails to address why someone remains sick.

In this episode, Dr. Spencer Zimmerman breaks down a major POTS review published in August 2026 and translates the findings into language patients and families can understand. He explains the different processes that may contribute to POTS, including small fiber and autonomic neuropathy, low blood volume, excessive sympathetic activation, and impaired blood flow and oxygen delivery to the brain.

You’ll also learn why normal oxygen saturation and blood pressure readings do not necessarily mean the brain is receiving adequate blood flow, which conditions most commonly overlap with POTS, and why migraines and irritable bowel syndrome may deserve more attention than they currently receive.

The episode also examines standard POTS treatments—including exercise, fluids, salt, compression garments, dietary changes, and medications—along with medications that may worsen symptoms. Finally, Dr. Zimmerman discusses what the current research may be missing, including vestibular and eye-movement dysfunction, cervical integration, overlooked lab findings, hormonal changes, and why neurological rehabilitation may need to come before traditional cardiovascular conditioning for some patients.
