    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.

    POTS, Orthostatic Hypotension, or Neurocardiogenic Syncope? How to Tell the Difference

    If you become dizzy, nauseous, weak, foggy, or feel like you might pass out when you stand, it is easy for everything to get labeled as POTS. But POTS is only one form of orthostatic intolerance. In this episode, Dr. Spencer Zimmerman breaks down the differences between POTS, orthostatic hypotension, and neurocardiogenic syncope. These conditions can cause very similar symptoms, but the changes in heart rate, blood pressure, and neurological regulation do not follow the same pattern. You’ll learn: What should normally happen to your circulation when you standHow POTS, orthostatic hypotension, and neurocardiogenic syncope are diagnosedWhy the timing of heart-rate and blood-pressure changes mattersWhich of these conditions can occur together—and which cannotWhy cardiac testing is still important, even when it comes back normalHow dehydration, anemia, medications, neurological conditions, and other factors can contributeWhy salt, fluids, compression, exercise, and medications help some people but not everyoneWhy receiving the correct diagnosis is only the beginning of understanding what you need to improveIf you have been diagnosed with dysautonomia but still do not understand why you are struggling or why the standard recommendations have only helped partially; this episode will help you see what may still be missing.

    POTS: Why It's Not About Your Heart Rate

    It is slightly too long for a podcast episode description. The content is good, but I’d tighten it so someone can understand the episode quickly without feeling like they have already consumed it. If your heart races every time you stand—but your cardiac testing keeps coming back normal—the heart may not be the real problem. POTS is diagnosed by changes in heart rate, but research suggests that the heart-rate increase may be a response to something happening earlier: an excessive drop in cerebral blood flow when you become upright. In this episode, Dr. Spencer Zimmerman explains why this matters, how the brain and autonomic nervous system normally regulate blood flow, and how impaired regulation may contribute to dizziness, brain fog, fatigue, shortness of breath, digestive problems, temperature intolerance, and other symptoms. You’ll also learn why salt, electrolytes, compression, and medications may help without fully explaining—or addressing—why you remain stuck. If you have POTS or dysautonomia and feel like no one has connected all your symptoms, this episode will help the bigger picture make more sense.

    Long COVID Isn't a Mystery — Here's the Research Showing What's Actually Happening in Your Brain

    If you've been told there's nothing more to do for your long COVID, or that the research just isn't there yet, this episode pushes back on both claims.  Dr. Zimmerman NP, DC, DACNB breaks down one of the most comprehensive 2025 research papers on the neurological effects of long COVID, walking through what's actually driving symptoms like brain fog, fatigue, dizziness, mood changes, and post-exertional malaise.  He covers the imaging and lab findings showing real, measurable brain changes, the overlapping mechanisms long COVID shares with POTS, MCAS, EDS, ME/CFS, and post-concussion syndrome, and why treating these as separate, isolated diagnoses keeps people stuck.  You'll learn why a single test or single treatment was never going to be the answer, what a layered, multimodal approach actually looks like, and why most people aren't failing because they're "defective" — they're failing because the approach they were given wasn't built for the complexity of what's really going on. This is research translated into something you can actually use, and a roadmap for the conversation to have with any provider willing to dig in with you.

    Why You Still Feel Dizzy (Even After “Normal” Tests) | The Real Causes of Chronic Dizziness

    Dizziness is one of the most common symptoms people struggle with… and one of the most misunderstood. If you’ve been told everything looks “normal,” yet you still feel off, this episode explains why. Instead of chasing a single cause, we break down a more accurate framework — looking at how dizziness can come from metabolic issues, inflammation, the immune system, vascular changes, the neck, and ultimately how the brain processes it all.  You’ll learn:  Why “normal labs” don’t always mean normal function  Why treatments work for some people but not others  The overlooked role of the brain, vision, and vestibular system  And why there’s no one-size-fits-all fix If you’re tired of guessing and want to understand what’s actually driving your symptoms, this episode will give you a completely different lens to look through. https://peakbrainandbody.com

    Migraines & Headaches Explained: Why Blocking the Pain Isn’t the Same as Solving the Problem

    Are your migraines or headaches still running your life—despite normal scans, multiple medications, and endless “try this” advice? In this research-backed Q&A, Dr. Spencer Zimmerman breaks down why migraines and chronic headaches are far more complex than most people are told. Instead of focusing on labels, he walks through the four core arenas that must be evaluated to truly reduce frequency and intensity: Immune system & inflammation (CGRP, histamine, gut health, autoimmune links)Vascular factors & autonomic regulationMitochondrial energy and metabolic efficiencyBrain connectivity (cerebellum, vestibular system, trigeminal pathways)You’ll learn: Why normal MRIs don’t mean “nothing is wrong”How medications like CGRP inhibitors work—and why they don’t solve the root causeThe hidden role of magnesium, riboflavin, omega-3s, and ketonesWhy gut health and brain health are inseparableHow caffeine and common OTC medications can perpetuate rebound headachesWhy no one is looking at brain connectivity—and why that mattersIf you’ve been told to “just manage it,” this episode will challenge that narrative and give you a systems-based framework for understanding what’s actually driving your migraines. Because the goal isn’t to block pain.  The goal is to prevent it. If you’re ready to understand your headaches differently—and explore what’s actually possible—this episode is for you. https://peakbrainandbody.com/

    POTS and Concussion: The Overlooked Neurological Link Behind Chronic Dizziness and Fatigue

    Still dizzy, foggy, exhausted—or dealing with racing heart symptoms—despite “normal” tests?  In this Q&A episode, Dr. Zimmerman explains why concussions and POTS are often misunderstood, why MRI/CT scans are usually normal in concussion, and what most evaluations miss (objective balance + eye-movement testing). He also breaks down POTS as a nervous system/autonomic issue, why patients get bounced between cardiology and neurology, and how immune/metabolic factors like histamine patterns and low ferritin can worsen symptoms. https://peakbrainandbody.com/concussion-symptoms-and-treatment/

    Why Some Concussions Don’t Heal: A Patient–Provider Conversation on Real Recovery

    A concussion story most people never hear. Dr. Zimmerman and his wife, Sara, share the raw, real experience of navigating yet another concussion—from subtle early symptoms to the emotional toll it takes on daily life. When symptoms don’t make sense—but your body knows something is wrong. Fatigue, mood swings, dizziness, nausea, memory lapses, and loss of motivation all appeared quickly, even after what seemed like a minor hit. Why standard care often leaves people stuck. Learn how normal scans, generic treatments, and symptom-chasing can miss the true neurological drivers of post-concussion symptoms. What actually made the difference this time. From vestibular and eye movement findings to targeted neurological therapies, hear how a personalized approach helped symptoms improve faster than expected. A powerful reminder for anyone who’s been told “this is just how it is.” This episode challenges the belief that chronic concussion symptoms are permanent—and explains why the right care matters more than ever.
