[20F] With long-standing episodes of lightheadedness and dizziness

What might be happening

Based on the symptoms and history you've provided, here are some possible explanations:

Postural Orthostatic Tachycardia Syndrome (POTS)

• Rationale: POTS is a condition that affects circulation (blood flow). It involves the nervous system and is characterized by an excessive increase in heart rate when moving from lying down to standing up. Symptoms often include lightheadedness, dizziness, near-fainting, and a rapid heart rate.
• Typical Treatments/Testing: Diagnosis often involves a tilt table test to measure heart rate and blood pressure changes. Treatment may include lifestyle changes, increased fluid and salt intake, medications to regulate blood pressure and heart rate, and physical therapy.

Anxiety or Panic Disorders

• Rationale: Anxiety and panic disorders can cause symptoms like a rapid heart rate, dizziness, and feeling hot. These symptoms can sometimes mimic other medical conditions.
• Typical Treatments/Testing: Diagnosis is usually based on a clinical evaluation. Treatment may include therapy (such as cognitive-behavioral therapy), medications (like SSRIs or benzodiazepines), and lifestyle changes.

PCOS-Related Hormonal Imbalances

• Rationale: Polycystic Ovarian Syndrome (PCOS) can cause hormonal imbalances that might contribute to symptoms like dizziness and feeling hot. However, it is less likely to be the primary cause of your heart rate changes and near-fainting episodes.
• Typical Treatments/Testing: Management of PCOS often involves hormonal treatments like birth control pills, lifestyle changes, and medications to manage symptoms.

What you can do

Lightheadedness, Dizziness, and Near-Fainting

• Long-Term Steps:
  • Keep a journal of your symptoms using MDandMe to track patterns and triggers.
  • Wear compression stockings to help improve blood flow.
  • Consult your healthcare provider for a thorough evaluation and possible tilt table test.

Increased Heart Rate

• Immediate Steps:
  • Practice deep breathing exercises to help calm your heart rate.
  • Avoid caffeine and other stimulants that can increase heart rate.
• Long-Term Steps:
  • Monitor your heart rate and note any patterns or triggers.
  • Discuss with your healthcare provider about possible medications to manage your heart rate.
