Your teen just got a POTS diagnosis, and one of the first questions that comes up, for you and often for them, is whether this was somehow written into their genes. Maybe a parent or grandparent had something similar. Maybe nobody in the family has ever dealt with anything like it. Either way, the genetic question deserves a real answer, and the honest one is more layered than a simple yes or no.
What POTS Actually Is
Postural Orthostatic Tachycardia Syndrome describes a nervous system that overreacts to a simple change in position. Moving from lying or sitting to standing triggers a rapid heart rate along with dizziness, fatigue, shakiness, headaches, brain fog, nausea, and sometimes chest discomfort. It's a condition of the autonomic nervous system specifically, the part of the body running heart rate, blood pressure, and digestion without any conscious effort. Estimates put POTS at somewhere between 1 and 3 million people in the United States, and for teenagers dealing with it, the daily disruption to school, activities, and social life can be significant.
The Genetic Piece
POTS does run in some families, which points toward a real inherited component for at least some cases. One gene that has drawn research attention is the norepinephrine transporter gene, which helps regulate a neurotransmitter tied directly to heart rate and blood pressure control. Some studies have found this gene altered more often in people with POTS, though the research is still developing. A handful of other genes tied to blood pressure regulation have also been studied for a possible connection.
Here's the piece that tends to surprise parents: even when a genetic link shows up in research, it rarely tells the whole story. Plenty of people diagnosed with POTS have no family history of it at all, and plenty of people who carry a genetic marker associated with POTS never develop the condition. Genetics can also shift in how they're expressed over the course of a life, which means how a gene gets switched on may end up mattering more than which genes were inherited in the first place.
What Else Shapes Whether POTS Develops
Environmental triggers appear to play a real role alongside any inherited tendency. Viral illness, physical trauma, and toxic exposure have all been connected to the onset of POTS in different individuals. Lifestyle factors matter too, hydration and electrolyte intake, activity level, and stress all influence how noticeable and severe symptoms end up being day to day. The clearest way to think about POTS is as a condition shaped by several factors layering together rather than any single genetic switch flipping on its own.
This layered picture also explains why POTS can show up seemingly out of nowhere after a viral illness or a growth spurt, even in a teenager with no prior symptoms and no known family history at all. The underlying tendency may have been present quietly for years, waiting on the right combination of stressors to make it visible. It also explains why two people with a nearly identical genetic profile, siblings, for instance, can have very different experiences with POTS, one severely affected and the other barely noticing anything at all.
The Nervous System View
Whatever mix of genetics and environment sets the stage, POTS ultimately comes down to an autonomic nervous system that has lost its ability to smoothly balance the sympathetic, fight or flight, side against the parasympathetic, rest and digest, side. The vagus nerve carries much of that parasympathetic signal, and when tension along the spine and upper neck interferes with it, the nervous system's ability to steady heart rate and blood pressure on standing gets harder to maintain, regardless of what set the pattern in motion to begin with.
This is part of why two teenagers with a similar genetic background can end up with very different symptom severity. A nervous system carrying additional physical stress, whether from a difficult birth, an old injury, or ongoing postural strain from years at a desk, has less capacity left to compensate when the autonomic system is already working harder than it should. Growth spurts add another layer of demand on top of that, since a rapidly lengthening body means blood vessels and cardiovascular reflexes have to keep adapting to keep pace, right at the age when POTS most often becomes noticeable.
Our Approach
We start by hearing your teen's story, when symptoms started, any family history, and what's already been tried. From there, INSiGHT neurological scanning gives us an objective look at how the autonomic nervous system is functioning, rather than relying on symptoms alone. Using light, nervous system focused adjustments, no cracking, popping, or twisting, our doctors work to ease tension patterns along the spine that interfere with vagus nerve signaling and autonomic balance.
Families often notice steadier energy through the day, fewer dizzy spells on standing, and better tolerance for standing in lines or gym class within the first several weeks of care, with continued improvement as regulation builds over a longer stretch.
What Helps Day to Day
- Steady hydration and electrolyte intake throughout the day, not just when symptoms flare
- Standing up slowly rather than all at once, giving the nervous system a moment to adjust
- Regular, gentle movement, since deconditioning tends to make POTS symptoms harder to manage over time
- Consistent sleep and meal timing, both of which support steadier autonomic function overall
Where to Go From Here
If your teen's POTS diagnosis has you wondering where it actually came from, or what to do next, our doctors in Royal Oak would be glad to help you make sense of the fuller picture. Our POTS and dysautonomia page covers our approach in more depth, and our free guide digs further into the nervous system side of it.
