Postural Orthostatic Tachycardia Syndrome — POTS — is one of the most misunderstood conditions I see. The core feature is simple to describe: when you stand up, your heart rate jumps abnormally, often by 30 beats per minute or more, and you feel it. Dizziness, lightheadedness, palpitations, fatigue, brain fog, and sometimes near-fainting follow. What’s not simple is why it happens — and that “why” is exactly where I focus.
Too often, POTS is treated as a single problem with a single pill. In my experience it’s better understood as a final common pathway that several different root causes can lead to. Some patients are chronically low on fluid volume. Some became deconditioned after an illness or a long period of bed rest, and their cardiovascular system lost its tone. Many develop POTS after a viral infection that appears to have disrupted the autonomic nervous system. In some patients a chronic inflammatory state is the driver: ongoing inflammation promotes vasodilation and pooling of blood in the vessels, so the circulation struggles to maintain pressure when you stand and the heart races to compensate. Others have connective-tissue factors in the mix. These are genuinely different problems, and they call for different solutions.
That’s why my first step is never to reach for a medication — it’s an investigation. What triggered this? What does your day actually look like — your fluid intake, your salt, your activity, your sleep? What do the details of your symptoms tell us about which POTS pattern you have? Answering those questions usually points toward a plan that addresses the cause, not just the racing heart.
None of this means POTS isn’t serious, or that medication and procedures never have a place — sometimes they do. When I think a change in medication is worth considering, I’ll say so and explain why, so you can take that recommendation to the doctor who prescribes for you — I don’t write prescriptions myself. My role as a consultant is to help you understand what’s driving your POTS and to build the diet, lifestyle, and supplement strategies around it. For a great many patients, those fundamentals — applied consistently and matched to the underlying driver — are the most powerful interventions of all. In the next article I’ll walk through what they actually are.
