Yes, you can develop POTS (postural orthostatic tachycardia syndrome) at any point in life, though it most commonly appears in adolescence or early adulthood. The average age of onset is 21, with the most common age being 14. POTS isn’t something you’re born with in most cases. It typically develops after a triggering event, and nearly half of all cases are preceded by a viral infection.
What POTS Actually Does to Your Body
POTS is a disorder of the autonomic nervous system, the part of your body that controls things you don’t think about: heart rate, blood pressure, digestion, temperature regulation. When you stand up, your body is supposed to make quick adjustments to keep blood flowing to your brain. In POTS, that system malfunctions, and your heart rate spikes to compensate.
The diagnostic threshold is a sustained heart rate increase of 30 or more beats per minute within 10 minutes of standing, without a major drop in blood pressure. For adolescents aged 12 to 19, the threshold is higher: 40 beats per minute. A diagnosis doesn’t require specialized tilt-table testing in most cases. A thorough clinical history and an active stand test, where you simply stand up while your heart rate is monitored, is sufficient for most people.
The Most Common Triggers
POTS rarely appears out of nowhere. Most people can point to a specific event that preceded their symptoms, even if the connection wasn’t obvious at the time.
Viral infections are the single most common trigger, preceding roughly half of all cases. Epstein-Barr virus (the cause of mono), influenza, upper respiratory infections, and stomach viruses have all been linked to POTS onset. COVID-19 has become a significant trigger as well, with POTS now recognized as a sequela of the virus. The working theory is that certain infections set off an autoimmune response that damages the nerves controlling circulation.
Physical stressors beyond infections can also set it off. These include major surgery, pregnancy, concussion, physical trauma, and even the hormonal shifts of puberty. Some cases have also been reported following immunization, though this is less common. In secondary POTS, the condition develops as a consequence of another disease that damages autonomic nerves, such as diabetes, Lyme disease, lupus, or Sjögren’s syndrome.
Why the Immune System Matters
There’s growing evidence that POTS is, at least in many cases, an autoimmune condition. Research has found that 89% of POTS patients in one study had elevated antibodies targeting a specific type of receptor on blood vessels (the alpha 1 adrenergic receptor) that helps control how blood vessels constrict. Over half also had antibodies against receptors involved in communication between nerves and muscles. These antibodies can interfere with the normal signals that tell your blood vessels to tighten when you stand, which is exactly the process that fails in POTS.
This autoimmune connection helps explain why viral infections are such a common trigger. The infection itself resolves, but the immune response it provoked continues attacking the body’s own tissue, specifically the receptors and small nerve fibers that regulate circulation.
Three Ways the Condition Develops
Not everyone with POTS has the same underlying problem. There are three recognized subtypes, and some people have features of more than one.
The most common form is neuropathic POTS, where small nerve fibers, particularly in the legs and feet, stop functioning properly. Up to 50% of patients show measurable damage to these fibers. When these nerves can’t signal your leg veins to constrict, blood pools in your lower body every time you stand, and your heart races to keep up.
In hypovolemic POTS, the core problem is low blood volume. Up to 70% of patients with POTS have reduced blood volume compared to healthy people. Their bodies paradoxically fail to activate the hormonal systems that should retain fluid and raise blood pressure, leaving them chronically low on circulating blood.
Hyperadrenergic POTS involves an excessive flood of stress hormones upon standing. People with this subtype often experience prominent anxiety, tremor, palpitations, and a noticeable rise in blood pressure alongside the rapid heart rate. Their bodies are essentially stuck in a fight-or-flight response every time they get upright.
Who Is Most Likely to Develop It
POTS has a striking demographic pattern. Women account for roughly 94% of diagnosed cases, with a female-to-male ratio of about 5 to 1. The condition predominantly affects white individuals (93% in one large survey). About half of patients develop symptoms during adolescence and half during adulthood, with a median onset age of 17.
There’s also a well-documented overlap with two other conditions: Ehlers-Danlos syndrome (a connective tissue disorder that causes joint hypermobility) and mast cell activation syndrome (a condition where immune cells release excessive inflammatory chemicals). Among people who have both POTS and Ehlers-Danlos syndrome, 31% also have mast cell activation syndrome, compared to just 2% in people without POTS. The odds of having all three together are more than 30 times higher than chance would predict. If you have one of these conditions, it’s worth knowing the symptoms of the others.
What Recovery Looks Like
POTS is not a life sentence for everyone, but it’s also not something that reliably resolves on its own. In a follow-up study of adolescent patients five years after their initial diagnosis at Mayo Clinic, only 19% reported recovery, and some of those still used treatments like heart-rate-lowering medications and increased salt and fluid intake. Adult-onset patients appear to fare worse than adolescents, though rigorous long-term data on adults is still limited.
Many people experience significant improvement even if they don’t fully recover. The trajectory varies enormously depending on the underlying subtype, the triggering event, and how well symptoms respond to lifestyle changes like increased fluid and salt intake, compression garments, and structured exercise programs that gradually recondition the cardiovascular system. For people whose POTS developed after a viral infection, symptoms sometimes improve as the autoimmune response fades over months or years, though predicting who will improve and who won’t remains difficult.
