You finally have a name for it. After months of your child's heart racing every time they stood up, the dizziness, the days too foggy and tired to get through school, someone finally said the word POTS instead of anxiety or growing pains. Relief and confusion tend to show up together at this point. What actually is this thing, and what do you do now.
What POTS Actually Is
Postural Orthostatic Tachycardia Syndrome, or POTS, is a disorder of the autonomic nervous system, the part of the body that runs heart rate, blood pressure, digestion, and temperature without your child ever thinking about it. The diagnosis itself comes from a specific number: a heart rate that climbs by 30 beats per minute or more within ten minutes of standing up, without the blood pressure drop that would point to a different condition. It affects an estimated one to three million people in the United States, and it shows up far more often in kids and teens than most parents realize.
The Symptoms Beyond the Fast Heartbeat
The racing heart is what gets tested for, but it is rarely the only thing your child is dealing with. Families commonly describe:
- Lightheadedness or dizziness on standing, sometimes to the point of nearly fainting
- Fatigue that does not improve with rest
- Trouble tolerating exercise or gym class
- Brain fog, trouble concentrating, or memory that feels unreliable
- Headaches and heart palpitations
- Shakiness or tremors
- Nausea, bloating, or other stomach symptoms
- Feeling too hot or too cold with no clear reason
- Trouble sleeping
Some kids have a mild version that mostly slows them down. Others miss weeks of school and pull back from friends and sports because functioning through a day feels like too much. Both ends of that range are real POTS.
Why the Nervous System Drives It
The autonomic nervous system runs on two branches working as a team. The sympathetic branch is the gas pedal, the fight or flight response that speeds the heart up under stress. The parasympathetic branch is the brake, the rest and digest side that calms things back down. In a child with POTS, that balance tips, with the gas pedal running hotter than it should and the brake, largely carried by the vagus nerve, not able to fully engage. Standing up is an ordinary daily transition, and a nervous system caught in that imbalance overreacts to it every time.
Birth stress, a difficult pregnancy, a rough delivery, or a run of childhood illness can all leave lasting tension in the upper neck, right where the vagus nerve begins its path down through the body. That tension does not show up on a standard exam, but it can quietly keep the nervous system leaning toward the gas pedal long after the original stress is gone.
Why So Many Families Hear It's Just Anxiety First
POTS is genuinely hard to diagnose because a racing heart, dizziness, and fatigue overlap with a long list of other conditions. A full evaluation usually involves a detailed history, orthostatic vitals checking heart rate and blood pressure lying down versus standing, and sometimes a tilt table test. Getting to an actual diagnosis after being dismissed for months is exhausting, and it is common enough that you are far from the only parent who has been through it.
How Our Doctors Approach POTS
Once a family comes to see us, we start by listening, the birth story, the timeline of symptoms, everything already tried. From there our doctors do a gentle exam of the spine and nervous system, often paired with INSiGHT scanning that measures heart rate variability, thermal patterns, and muscle tension along the spine, to get an actual picture of where the autonomic nervous system is stuck. Care itself is light, nervous system focused contacts aimed at the upper neck and spine, nothing forceful, built around helping the vagus nerve and the parasympathetic side of things do their job again. Every child's plan is built around what their scans and symptoms actually show.
Questions Worth Asking at the Diagnosis Appointment
A new diagnosis appointment tends to move fast, and it helps to walk in with a short list ready. Worth asking about include which subtype of POTS your child's numbers point toward, since neuropathic, hyperadrenergic, hypovolemic, and secondary POTS can each call for a somewhat different focus. It is also worth asking what a realistic day to day plan looks like for school attendance, gym participation, and sports, since so much of managing POTS well comes down to pacing rather than pushing through. Ask what monitoring will happen over the next few months, and what specific changes would be worth a call between appointments.
Many families also want to know why their child developed POTS in the first place. The honest answer is that there are several recognized paths into it, small fiber nerve involvement, elevated stress hormones, lower blood volume, or an underlying condition such as Ehlers-Danlos syndrome. Some cases also follow a viral illness, with a growing body of reporting linking post viral autonomic changes to POTS symptoms in kids who previously had no history of it. None of these paths are more or less real than the others, and figuring out which one fits your child is part of what makes a thorough evaluation worth the time.
Where to Go From Here
A new diagnosis is a starting point, not a life sentence. If your child has been diagnosed with POTS or a related dysautonomia, our doctors in Royal Oak would love to take a look at what is going on in their nervous system.
