POTS names what your heart does when you stand. Our team looks for why it happens. Start with the racing heart itself, then the conditions it gets mistaken for, the symptoms that come with it, what helps and what recovery looks like.
Compare POTS medications, from beta blockers and ivabradine to midodrine, and see how salt, exercise and our team's brain-first rehab fit in.

Your heart races when you stand because your brain is losing blood flow, a measurable regulation failure, not anxiety. Here's what's actually happening.
What causes the high heart rate in POTS? The heart speeds up to rescue blood flow to your brain. Why it happens, what beta blockers reveal and what to measure.
POTS isn't one thing. Understanding the three subtypes, neuropathic, hyperadrenergic, and hypovolemic, is the first step toward treatment that works.
Hyperadrenergic POTS (hyperPOTS) is POTS with a norepinephrine surge on standing. See the symptoms, how it's tested, what beta blockers miss and what to check.
Orthostatic intolerance means symptoms when you stand that ease when you lie down. Symptoms, causes, and the types: orthostatic hypotension, POTS and OCHOS.
If your blood pressure looks normal and your heart rate doesn't quite qualify, you've been told nothing is wrong. Here's what the standard test misses.
The autonomic nervous system isn't an on/off switch. Learn why 'sympathetic dominance' is misleading and how specific pathways drive POTS symptoms.
POTS or anxiety? How to tell which comes first, why POTS is so often misdiagnosed as anxiety, what testing shows, and a case where the body led.
FND and POTS can show up together. What FND is, how it differs from POTS, why standing can make FND symptoms worse, and what a tilt test can show.
Why so many POTS cases get dismissed, why clean labs don't mean you're fine, and how a brain-first approach finds what standard workups miss.
A POTS diagnosis can be a relief, but for many the treatments still don't work. Here's why, and what understanding your specific mechanism changes.
Small fiber neuropathy shows up in a quarter to half of POTS patients tested. How SFN drives dysautonomia, why a skin biopsy can miss it, and what improves it.
How MCAS and dysautonomia connect: what histamine does to blood flow and heart rate in POTS, how to tell the 2 apart, and what helps when both flare.
POTS and EDS often show up together. See what studies show about the overlap, why the numbers vary, whether EDS causes POTS and how our team evaluates it.
Can B6 toxicity cause POTS? Learn about vitamin B6 and autonomic nerves, how to start moving again with POTS, and hypoplastic vertebral arteries.
Does deconditioning cause POTS, or POTS cause deconditioning? What bed rest does to the heart, POTS vs being out of shape, and what exercise can and can't do.
POTS and ME/CFS can overlap, and a normal heart rate on a tilt can hide falling brain blood flow. Here's how our team separates them by mechanism.
In neuropathic POTS, nerves to the leg vessels are partly lost and blood pools when you stand. See what causes it, how it's tested and how our team treats it.
Blood pooling is blood collecting in your legs, feet or hands when you stand. What it looks like, why ankles swell, when it's normal, and its POTS causes.
Heat, heavy meals, illness, standing still and the menstrual cycle can all set off a POTS flare. See what studies show, what to do and when to get help.
POTS is often worse in the morning. See what studies show about standing heart rate and test timing, plus our team's view on the neck and sleep posture.
Seizure-like spells in POTS are often convulsive syncope: a faint with brief jerks. How to tell it from a seizure, what testing shows, and when to get help.
Why heat makes POTS worse: what heat does to brain blood flow and CO2, what the research shows, and how our team builds heat and sun tolerance.
For most people with POTS, low blood volume is not the core problem. Here is why salt and water hit a ceiling, and what fluid dumping really means.
Why POTS and dysautonomia cause nausea, bloating, and gastroparesis. The gut isn't broken; the brain's control of it is. The autonomic-GI connection.
What causes brain fog, why it can get worse when you stand or drive, and how to find which link in your brain's supply chain is weak.
POTS brain fog is slowed thinking and poor focus that often worsens on standing. See what studies show about brain blood flow and what our team tests.
Ear fullness, popping, or a heartbeat in your ear with POTS? It often traces to how blood drains from your head, not just your eustachian tubes.
Feeling detached from reality with POTS or dysautonomia? Derealization is often a blood-flow and vestibular signal, not just anxiety. What it means.
Why exercise feels so hard with POTS: the symptoms, what research shows about the heart and fitness, what our team finds in the brain, and what helps.
Air hunger in POTS feels like a breath that never fills. See what research shows about breathing on standing and how strong the evidence for breathing exercises is.
POTS symptoms by body system, from a racing heart to brain fog and nausea, with a printable checklist and how our team tests brain blood flow.
Hypovolemic POTS is tied to low blood volume, yet salt and fluids often stall. Our team explains the symptoms, the tests and why volume isn't the whole story.
How often POTS shows up in long COVID across 3 studies, why heart rate and dizziness change when you stand, and what our team measures first.
Dysautonomia is increasingly recognized after concussion. See what studies show about POTS after a head injury and what a racing heart can tell you.
No controlled study has tested craniocervical instability as a cause of POTS. See what the imaging and surgery research shows and how our team reads the neck.
What the research shows about thoracic outlet syndrome and dizziness, why no study links TOS to POTS yet, and how our team checks for compression.
Can mold, Lyme or CIRS cause POTS? What studies show on mold, CIRS testing and post-treatment Lyme, and what our team checks first.
IIH and POTS can occur together. Learn what IIH is, how it's confirmed, which symptoms overlap with POTS, and why vision changes need prompt care.
Does salt help POTS? See the consensus doses for salt and water, what studies show about how much and how fast, and what salt and water can miss.
Do SSRIs help POTS? What the one randomized SSRI trial found, why SNRIs and ADHD drugs can raise standing heart rate, and how to talk with your prescriber.
IV saline helps ME/CFS and dysautonomia patients feel better temporarily. But if the problem is blood flow distribution, saline is a patch, not a fix.
Exercise advice fails POTS patients because it ignores orthostatic blood flow. Deconditioning isn't the cause. Fix cerebral perfusion first.
Why do so many dysautonomia treatments fail? Both conventional and functional medicine miss the one core problem: the brain is the common thread.
Vagus nerve stimulation for POTS misses the point. The vagus is mostly sensory, paired antagonism is a myth, and the real driver of dysautonomia differs.
POTS and dysautonomia treatment should recalibrate your nervous system, not just manage symptoms. Targeting the lynchpin unlocks recovery.
POTS is a brain regulation problem, not a heart rate problem. Mechanism-based neurological evaluation identifies what's actually driving symptoms.
Is POTS neurological or cardiac? What each kind of POTS specialist tests and treats, the questions to ask, and what testing to expect.
