How to Be Diagnosed with Postural Orthostatic Tachycardia Syndrome

What is Postural Orthostatic Tachycardia Syndrome (POTS)?

Definition and Description of POTS: Postural Orthostatic Tachycardia Syndrome (POTS) is a condition characterized by an abnormally fast heart rate (tachycardia) upon standing up from a lying or sitting position. This increase in heart rate is often accompanied by other symptoms such as lightheadedness, dizziness, fainting, fatigue, shortness of breath, chest pain, vision changes, and cognitive difficulties. POTS can significantly impact daily life, affecting activities like work, school, and social interactions.

Common Symptoms and How They Affect Daily Life:

  • Dizziness and Lightheadedness: These symptoms can make it difficult to drive, walk, or stand for extended periods.
  • Rapid Heartbeat: The increased heart rate can cause palpitations, chest discomfort, and anxiety.
  • Fatigue: POTS-related fatigue can be debilitating, interfering with energy levels and overall well-being.
  • Other Symptoms: Shortness of breath, vision changes, cognitive fog, and headaches can further impair daily functioning.

Importance of an Accurate Diagnosis: An accurate diagnosis of POTS is essential for receiving appropriate treatment and managing the condition effectively. Without proper diagnosis, individuals may suffer from unnecessary medical tests, ineffective treatments, and ongoing symptoms that significantly impact their quality of life.

Recognizing the Symptoms of POTS

Detailed List of Physical, Emotional, and Cognitive Symptoms:

  • Physical Symptoms: Dizziness, lightheadedness, rapid heartbeat, palpitations, chest pain, shortness of breath, fainting, near-fainting, fatigue, muscle weakness, tremor, nausea, and abdominal discomfort.
  • Emotional Symptoms: Anxiety, panic attacks, irritability, and mood swings.
  • Cognitive Symptoms: Brain fog, difficulty concentrating, memory problems, and impaired decision-making.

Differences Between POTS and Other Conditions with Similar Symptoms: Several other conditions can mimic POTS symptoms, making diagnosis challenging. These include:

  • Dehydration: Replenishing fluids can often resolve dehydration-related symptoms.
  • Anemia: Iron deficiency can cause fatigue, dizziness, and shortness of breath.
  • Medications: Certain medications can trigger orthostatic hypotension and related symptoms.
  • Cardiac Conditions: Underlying heart problems can cause similar symptoms, requiring specialized evaluation.

Examples of How Symptoms Can Vary Between Individuals: The presentation of POTS symptoms varies greatly among individuals. Some people experience mild symptoms that occur occasionally, while others have severe and debilitating symptoms that significantly impact their daily lives.

When to Seek Medical Help

Indications of When It’s Crucial to Consult a Doctor:

  • Persistent Symptoms: If POTS symptoms occur frequently and interfere with daily activities, seeking medical attention is crucial.
  • Worsening Symptoms: A sudden worsening of symptoms or the development of new symptoms warrants immediate medical evaluation.
  • Fainting or Near-Fainting Episodes: Fainting or near-fainting episodes require prompt medical attention.

Risks of Delaying Medical Help:

  • Undiagnosed and Untreated POTS: This can worsen symptoms and hinder quality of life.
  • Misdiagnosis and Inappropriate Treatment: This can lead to unnecessary medical interventions and delays in effective treatment.
  • Complications: In severe cases, POTS can lead to dehydration, electrolyte imbalances, and even heart failure.

Tips for Documenting and Communicating Symptoms to the Doctor:

  • Keep a Symptom Diary: Record the date, time, duration, and severity of symptoms, along with any triggers or activities that worsen them.
  • Describe Symptoms in Detail: Provide clear and concise descriptions of your symptoms, including any associated sensations or changes in bodily functions.
  • Note Any Patterns: Identify any patterns or triggers that seem to correlate with symptom episodes.

Initial Medical Evaluation

What to Expect During the First Visit to the Doctor:

  • Medical History Review: The doctor will review your medical history, including past illnesses, medications, allergies, and family history.
  • Physical Examination: The doctor will perform a physical exam to check for signs of underlying medical conditions.
  • Discussion of Symptoms: The doctor will discuss your symptoms in detail, including their frequency, severity, and impact on your life.

Common Questions Doctors May Ask:

  • When do you experience symptoms most often?
  • What activities trigger your symptoms?
  • How long do the symptoms last?
  • Are there any other symptoms accompanying your primary complaints?

By providing detailed and accurate information during your medical evaluation, you can help your doctor make a more accurate diagnosis and develop an effective treatment plan.


Recognizing the symptoms of POTS and understanding the importance of seeking medical help is crucial for proper diagnosis and treatment. Keeping a detailed record of symptoms and being prepared to discuss them with your doctor can lead to a more accurate diagnosis and effective management of the condition.

If you suspect you or a loved one might have POTS, don’t hesitate to seek medical advice. Early diagnosis and appropriate treatment can significantly improve the quality of life.

A proper diagnosis is the first step toward managing POTS effectively. With the right medical support, individuals with POTS can lead fulfilling lives despite the challenges posed by the condition.
