Have you ever stood up too quickly and suddenly felt dizzy, lightheaded, or noticed your heart racing?

For most people, that feeling passes quickly. But imagine experiencing those symptoms regularly, sometimes from something as simple as standing in line, taking a warm shower, or walking across a room.

For individuals living with Postural Orthostatic Tachycardia Syndrome (POTS), these everyday activities can become surprisingly challenging.

POTS is often misunderstood, partly because many of its symptoms aren’t visible to others. Understanding what happens inside the body can help bring awareness to a condition that affects daily life in ways we may not immediately recognize.

Let’s explore what POTS is, why it happens, and what individuals experiencing these symptoms should know.

What Exactly Is POTS?

POTS is a condition involving the autonomic nervous system, which controls many of the functions our bodies perform automatically, including heart rate, blood pressure, digestion, and temperature regulation.

Normally, when we stand up, gravity pulls some of our blood toward our lower body. Our nervous system responds by adjusting blood vessel activity and heart rate to maintain circulation.

For someone with POTS, this adjustment doesn’t work as efficiently. Their heart rate increases excessively when they move into an upright position, often accompanied by uncomfortable symptoms.

In adults, one diagnostic criterion is a sustained heart rate increase of at least 30 beats per minute within 10 minutes of standing, without a significant drop in blood pressure. For adolescents ages 12–19, the threshold is generally 40 beats per minute.

However, a racing heart alone doesn’t mean someone has POTS. A healthcare professional must evaluate symptoms and rule out other possible causes.

Recognizing the Symptoms

POTS doesn’t look the same for everyone. Some individuals experience relatively mild symptoms, while others find that everyday activities become difficult.

Common symptoms include:

• Dizziness or lightheadedness when standing

• Rapid heartbeat or heart palpitations

• Extreme fatigue

• Brain fog or difficulty concentrating

• Blurred vision

• Nausea or digestive discomfort

• Headaches

• Shakiness or weakness

• Feeling faint or fainting

• Difficulty exercising or tolerating heat

Symptoms may worsen with dehydration, prolonged standing, hot environments, illness, or physical exertion.

One particularly challenging aspect of POTS is that many symptoms are invisible. Someone may appear perfectly healthy while experiencing significant physical discomfort.

What Causes POTS?

Researchers are still working to understand the different mechanisms behind POTS, and there isn’t one single cause.

Some individuals develop symptoms following a viral illness, surgery, pregnancy, or another significant physical stressor.

POTS has also been associated with certain conditions, including hypermobile Ehlers-Danlos syndrome, autoimmune disorders, and long COVID.

Researchers continue to investigate how blood volume, immune function, circulation, and nervous system signaling may contribute to the condition.

Although these associations are important, having one of these conditions doesn’t necessarily mean someone will develop POTS.

How Is POTS Diagnosed?

Because POTS shares symptoms with several other medical conditions, receiving an accurate diagnosis may take time.

Healthcare professionals typically begin by reviewing medical history and evaluating symptoms.

They may measure heart rate and blood pressure while lying down and standing or recommend a tilt-table test to observe how the body responds to changes in position.

Additional testing may help rule out other explanations, such as dehydration, anemia, thyroid disorders, medication effects, or heart-related conditions.

If you’re experiencing recurring symptoms, documenting when they happen and discussing them with your healthcare provider can be a helpful starting point.

Managing POTS and Supporting Overall Wellness

Although there is currently no universal cure for POTS, many individuals can improve their symptoms through personalized treatment and management strategies.

Depending on individual health needs, healthcare professionals may recommend:

• Hydration: Maintaining adequate fluid intake to support blood volume and circulation.

• Sodium adjustments: Increasing salt intake when medically appropriate to help maintain blood volume.

• Compression garments: Helping reduce blood pooling in the lower body.

• Structured movement: Gradually improving physical conditioning through an individualized exercise program.

• Trigger awareness: Recognizing how heat, prolonged standing, dehydration, or illness affect symptoms.

• Medication: Managing heart rate, circulation, or other symptoms when prescribed by a healthcare professional.

Some individuals also explore complementary wellness practices to support relaxation, mobility, and overall well-being.

However, natural or holistic approaches are not automatically safe or appropriate for everyone, and they have not been established as cures for POTS.

Even seemingly simple changes, such as increasing sodium intake or beginning a new exercise routine, should be discussed with a qualified healthcare professional.

What works for one person may not work for another. Individualized care is especially important when managing a condition that affects multiple systems throughout the body.

Why Awareness Matters

Living with an invisible condition can be frustrating, especially when symptoms are misunderstood or dismissed.

Something as simple as standing through a conversation, taking a hot shower, or spending time outdoors on a warm afternoon can become physically exhausting for someone experiencing POTS.

Because symptoms may fluctuate, individuals can have good days and difficult days, sometimes without an obvious explanation.

Greater awareness encourages understanding, informed conversations, and appropriate medical evaluation.

It also reminds us that we can’t always recognize someone’s health challenges simply by looking at them.

The Takeaway

POTS is more than occasionally feeling dizzy when standing. It’s a complex condition involving how the body regulates heart rate and circulation.

While researchers continue working to better understand its causes and treatment options, awareness remains an important part of helping individuals recognize symptoms and seek appropriate care.

If you or someone you know experiences frequent dizziness, a rapid heartbeat upon standing, fainting, or unexplained fatigue, consider discussing these symptoms with a qualified healthcare professional. Seek emergency care for chest pain, severe difficulty breathing, or fainting accompanied by other concerning symptoms.

At Natural Health Network, we believe education gives individuals the tools to ask questions, explore their options, and make informed decisions about their health and well-being.
