standing up and suddenly feeling your heart racing, followed by a wave of dizziness or even the sensation that you might pass out? If this happens regularly, you may be experiencing symptoms of Postural Orthostatic Tachycardia Syndrome (POTS). This condition affects blood circulation and can interfere with daily activities, often leaving people feeling weak, fatigued, or lightheaded.
Understanding POTS
Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system, which controls involuntary functions such as heart rate, blood pressure, and digestion.
POTS is diagnosed when a person’s heart rate increases by 30 beats per minute (or more) within 10 minutes of standing, without a major drop in blood pressure. This irregular response can cause dizziness, heart palpitations, fatigue, and even fainting. While POTS is most commonly seen in young women, it can affect people of any age.
Why Does POTS Occur?
The exact cause of POTS is still being studied, but it is often linked to several factors, including:
Neuropathic POTS: Nerve damage disrupts blood vessel constriction, causing blood to pool in the lower body.
Hyperadrenergic POTS: Excess norepinephrine triggers an overactive nervous system, increasing heart rate and blood pressure.
Hypovolemic POTS: Low blood volume leads to circulation problems, making it difficult for the body to regulate blood pressure.
Autoimmune-Related POTS: Some individuals with POTS also have autoimmune conditions, suggesting a potential immune system connection.
POTS presents a variety of symptoms, which can range from mild to severe:
✅ Heart palpitations and dizziness when standing ✅ Fainting or near-fainting episodes ✅ Increased heart rate (tachycardia) ✅ Fatigue and muscle weakness ✅ Brain fog and difficulty focusing ✅ Shortness of breath ✅ Intolerance to exercise ✅ Irregular sweating patterns ✅ Digestive problems (nausea, bloating, stomach discomfort) ✅ Sensitivity to heat or cold ✅ Tingling or numbness in the legs ✅ Frequent urination ✅ Sensitivity to bright lights or loud noises ✅ Migraines or headaches ✅ Anxiety or low mood
For some individuals, these symptoms can be mild, while for others, they can be severe enough to impact their ability to perform daily tasks.
Managing POTS and Reducing Symptoms
While POTS does not have a single cure, there are several effective ways to manage symptoms and improve quality of life.
1. Lifestyle Modifications
Stay Hydrated: Drinking 2-3 liters of water daily helps stabilize blood circulation.
Increase Salt Intake: Sodium assists in retaining fluids, helping to regulate blood pressure.
Wear Compression Garments: Compression socks or abdominal binders prevent blood from pooling in the lower body.
Change Positions Gradually: Moving slowly from sitting to standing can reduce dizziness.
Exercise: Low-impact activities like swimming, cycling, or rowing help build tolerance and improve circulation.
2. Medications
Doctors may prescribe medications to help regulate symptoms, such as:
Fludrocortisone: Increases blood volume.
Midodrine: Encourages blood vessel constriction to prevent blood pooling.
Beta-blockers: Help slow down an overactive heart rate.
Ivabradine: Regulates heart rate while maintaining normal blood pressure.
SSRIs (Selective Serotonin Reuptake Inhibitors): Aid in balancing the autonomic nervous system.
3. Physical Therapy
A structured exercise program that focuses on gradual cardiovascular and strength training can improve circulation and reduce symptoms over time.
4. Dietary Changes
Eat small, frequent meals to avoid sudden drops in blood pressure.
Avoid caffeine and alcohol, which can lead to dehydration and worsen symptoms.
Ensure proper electrolyte intake to support muscle and nerve function.
5. Treating Underlying Conditions
If POTS is linked to autoimmune disorders, neuropathy, or hypovolemia, addressing these underlying issues can help manage symptoms more effectively.
When to Seek Medical Help
If you often experience heart palpitations, dizziness, fainting, or severe fatigue, it’s important to consult a specialist. POTS is frequently misdiagnosed as anxiety or panic disorder, making it essential to seek care from a clinic that specializes in autonomic nervous system disorders—such as The Heartbeat Clinic—for an accurate diagnosis and customized treatment plan.
At The Heartbeat Clinic, we provide in-depth evaluations and personalized treatment plans to help patients with POTS regain control over their symptoms and improve their quality of life. Don’t let POTS disrupt your daily activities—schedule an appointment today!
