A racing heart every time you stand. Dizziness that arrives without warning. Exhaustion that sleep does not fix. Those symptoms are hard enough on their own, and being told your tests look normal makes them harder.
A POTS specialist is a physician who evaluates orthostatic symptoms in a systematic way: confirming the heart rate response to standing, ruling out the conditions that imitate POTS, identifying which mechanism is driving your symptoms, and then building a treatment plan around that. This page explains how POTS diagnosis works, what postural orthostatic tachycardia syndrome treatments actually involve, and what to expect from a dedicated POTS clinic in the Dallas-Fort Worth area.
POTS is a chronic condition in which the heart rate rises excessively when you move from lying or sitting to standing, without the drop in blood pressure that defines orthostatic hypotension. It belongs to a wider group of conditions called dysautonomia, which affect the autonomic nervous system. That system controls the functions you never think about: heart rate, blood pressure, digestion, temperature regulation, and blood flow.
When the autonomic response to standing does not work correctly, blood pools in the lower body. The heart compensates by beating faster. That compensation is what produces the palpitations, lightheadedness, breathlessness, and brain fog that patients describe.
POTS is not considered life-threatening, and no increased mortality has been reported in the medical literature. It is, however, genuinely disabling for many people, and it deserves proper evaluation rather than reassurance alone.
International expert consensus defines POTS using three requirements that must be present together:
Standing heart rates in POTS are often 120 beats per minute or higher, and the response is usually stronger in the morning than in the evening. The tachycardia also has to be explained by POTS rather than by another cause, which is why a proper work-up matters.
An important update: an international multidisciplinary expert consensus published in The American Journal of Medicine in 2026 noted that many patients have clear orthostatic intolerance, autonomic dysfunction, and real functional impairment even when their heart rate increase falls short of the numerical threshold. These patients have historically been left undiagnosed and untreated. Good specialist care treats the number as one piece of evidence, not as the entire diagnosis.
Expert consensus estimates put the prevalence at roughly 0.2% to 1% of the United States population, which is somewhere between one and three million people. Most patients first develop symptoms between the ages of 15 and 25, and more than 75% of those diagnosed are female. POTS is also now recognised as a feature of long COVID, and the American Autonomic Society has issued guidance specifically on post-COVID postural tachycardia syndrome.
POTS affects several body systems at once, which is exactly why it is so often missed. In one of the largest patient surveys conducted, involving 4,835 people with a physician diagnosis of POTS, the most frequently reported symptoms were lightheadedness (99%), tachycardia (97%), presyncope (94%), headache (94%), and difficulty concentrating (94%). Common symptoms include:
The same survey found that patients waited a median of 24 months between first seeing a physician and receiving a POTS diagnosis, and around 15% waited more than 10 years. A commentary on that data noted patients had typically seen about seven different specialists before the correct diagnosis was made.
The reason is straightforward. The symptoms overlap with anxiety, anaemia, thyroid disease, chronic fatigue, and inappropriate sinus tachycardia. Unless someone actually measures your heart rate and blood pressure in both lying and standing positions, the pattern that defines POTS never gets recorded. A specialist for POTS starts with that measurement rather than ending with it.
POTS diagnosis is a process of confirmation and exclusion. Here is what a thorough evaluation looks like.
POTS is not one single mechanism, and identifying yours shapes the treatment plan. Several mechanisms have been described, and they frequently overlap in the same patient:
You can read more about the underlying mechanisms on our what causes POTS page.
The honest answer to “is there a treatment for POTS” is yes, and the honest answer to “is there a cure” is not yet. No single therapy works for everyone, and most patients do best on a combination of approaches built up over time. The goal of treatment is to reduce symptoms, restore function, and help you get back to work, study, and daily life.
Expert consensus is clear that non-drug treatment should be attempted first with all patients.
The section below explains the categories of care that POTS specialists use. It is not a treatment plan and it is not a prescription. Nothing here should be started without speaking to a physician who has assessed you.
A regular, structured, and progressive exercise programme is one of the most strongly supported treatments for POTS. The critical detail is how it starts. Training should begin with non-upright exercise, such as a rowing machine, a recumbent cycle, or swimming, so that you can build fitness without provoking the orthostatic stress that triggers your symptoms. Aerobic reconditioning is combined with some resistance work for the thighs. As tolerance improves, duration, intensity, and upright activity are added gradually. Supervision matters here. Starting too hard is the most common reason patients abandon exercise therapy, and our exercise physiology team sets the progression around your current capacity rather than a generic schedule.
When non-drug measures do not give enough relief, medical treatment may be considered. We deliberately do not name medications, doses, or supplements on this page. POTS has several different mechanisms, and a treatment that helps one patient can make another patient worse. Choosing safely requires your test results, your full medical history, and a review of everything you already take. That assessment can only happen in a clinical appointment. If you want to know what treatment options apply to your situation, speak with Dr. Suleman directly. Book a consultation or call 214-504-9942, and please do not start, stop, or change any treatment based on information you find online, including this page.
Some patients go through short-term flares where symptoms worsen sharply. In these situations your specialist may provide supervised support in the clinic to help stabilise symptoms. This is given as short-term rescue care under medical supervision, not as a routine ongoing therapy. If your symptoms are worsening, contact our office rather than managing a flare alone.
Patients researching POTS online will encounter procedures presented as cures. Expert consensus specifically advises against the routine use of sinus node modification by ablation, surgical correction of Chiari malformation type I, and balloon dilation or stenting of the jugular vein in patients with POTS, noting these are potentially harmful. If a procedure is being recommended to you, ask what evidence supports it in POTS specifically.
POTS tends to fluctuate, with better periods and worse periods, and its course varies considerably between patients. Many people improve substantially with consistent management. Our article on POTS prognosis covers the long-term outlook in more detail.
Expert guidance notes that POTS is often best managed with a multidisciplinary approach that can include physicians, nurses, physical therapists, exercise specialists, and psychological support.
That is difficult to arrange across separate practices. A dedicated POTS treatment center brings the testing, interpretation, and ongoing management into one place, which matters for a condition where:

What is the treatment for POTS?
Expert consensus recommends starting with non-drug measures for all patients: fluid and dietary salt intake under medical supervision, compression garments, sleeping with the head of the bed raised, physical counter-pressure manoeuvres, and a structured, progressive exercise programme that begins with non-upright activity. Medical treatment may be considered when these measures are not enough. We do not recommend specific medications online, because the right choice depends on your subtype, your test results, and your full medical history. Speak with Dr. Suleman to find out what applies to you.
Is there a cure for POTS?
There is no established cure at present, and no single therapy works for every patient. POTS is managed rather than cured. Many patients improve significantly with consistent treatment, and the condition often fluctuates over time.
What is the best treatment for POTS syndrome?
There is no single best treatment, because POTS has several different mechanisms. Structured exercise reconditioning combined with measures that expand blood volume has the strongest supporting evidence. Beyond that, care is tailored to whether your presentation is mainly neuropathic, low volume, or hyperadrenergic, which is something a specialist determines through testing rather than something you can identify from symptoms alone.
How do you get diagnosed with POTS?
Diagnosis begins with a full clinical history, a physical examination including orthostatic vital signs, and a 12-lead ECG. If the standing heart rate response needs confirmation, a tilt table test is used. Blood tests, Holter monitoring, an echocardiogram, and exercise testing help exclude other causes. Extended autonomic testing is reserved for cases that remain unclear or do not respond to treatment.
What heart rate increase confirms POTS?
An increase of 30 beats per minute or more within 10 minutes of standing or head-up tilt in adults, or 40 beats per minute or more in people aged 12 to 19, alongside at least three months of orthostatic symptoms and without a fall in systolic blood pressure greater than 20 mm Hg.
Can I have POTS if my heart rate does not rise by 30 bpm?
Possibly. International expert consensus published in 2026 recognised that many patients have genuine orthostatic intolerance, autonomic dysfunction, and functional impairment without meeting the heart rate threshold. These patients still need evaluation and treatment, even though a formal POTS label may not apply.
What is the immediate treatment for POTS symptoms?
During an episode, many patients are advised to lie down with the legs raised and use counter-pressure manoeuvres such as leg crossing and muscle tensing until symptoms settle. If flares are frequent or severe, that is a reason to be assessed rather than to self-manage. Contact our office on 214-504-9942 so your specialist can review what is triggering them.
Which specialist treats POTS?
POTS is most often diagnosed by cardiologists and neurologists, though it crosses several specialties. What matters more than the specialty label is whether the physician performs orthostatic testing, understands the subtypes, and can manage the condition over the long term.
Do I need a referral to be seen?
Referral requirements vary by insurance plan. Contact our office on 214-504-9942 and our team will confirm what your plan needs before your visit.
If standing makes your heart race, if you have been told your tests are normal but you know something is wrong, or if you have been managing POTS alone for years, a structured evaluation is the place to start.
