Postural Orthostatic Tachycardia Syndrome (POTS) affects the autonomic nervous system, causing a wide range of symptoms that can significantly impact daily life.
Despite its prevalence, many symptoms are often overlooked or misdiagnosed, leaving individuals searching for answers.
In this article, we’ll explore 21 surprising signs of POTS you should know about to better understand this condition and seek proper care.
1. Persistent Dizziness
One of the hallmark symptoms of POTS is dizziness, particularly when transitioning from sitting or lying down to standing.
This happens because the autonomic nervous system struggles to regulate blood flow, leading to a temporary drop in blood supply to the brain.
For many, this dizziness can feel like the room is spinning or like they’re on the verge of fainting.
If you frequently experience dizziness without a clear cause, it might be worth discussing with your doctor, especially if other symptoms accompany it on this list.
2. Rapid Heart Rate (Tachycardia)
A sudden increase in heart rate upon standing is one of the defining features of POTS. This rapid heart rate, or tachycardia, can feel like your heart is racing even when you’re not exerting yourself.
Medical professionals often use a tilt table test to measure heart rate changes for a diagnosis. If you notice that your heart seems to race or pound shortly after standing, it’s a sign that shouldn’t be ignored.
3. Chronic Fatigue
Chronic fatigue in POTS can feel like a deep, unrelenting tiredness that doesn’t improve with rest. This isn’t the same as being tired after a long day; it’s a level of exhaustion that impacts your ability to function.
Many people with POTS describe feeling like they’re running on empty even after a full night’s sleep. This symptom often overlaps with conditions like chronic fatigue syndrome, making it even harder to pinpoint.
4. Brain Fog
Brain fog is a term used to describe cognitive difficulties such as trouble concentrating, memory issues, and feeling mentally “fuzzy.” In POTS, brain fog often worsens after standing or during times of physical exertion.
It can complicate tasks like reading, writing, or following a conversation. Staying hydrated and taking breaks throughout the day can sometimes help, but brain fog remains one of the more frustrating symptoms for many.
5. Fainting Spells
Fainting, or syncope, is another common symptom of POTS. This occurs when blood flow to the brain is temporarily reduced, causing loss of consciousness.
While not everyone with POTS faints, those who do often find it a disruptive and sometimes dangerous symptom. Recognizing early signs like lightheadedness or vision changes can help prevent falls and injuries.
6. Chest Pain
Chest pain in POTS can feel like a sharp or pressing discomfort and may mimic symptoms of a heart attack.
While this can understandably cause alarm, it’s often related to blood flow issues rather than heart disease. It’s still crucial to seek medical advice to rule out other potential causes of chest pain.
7. Shortness of Breath
Many people with POTS report experiencing shortness of breath, even when at rest. This can feel like you’re not getting enough air or your breathing is unusually shallow.
Since shortness of breath can be linked to several health conditions, it is important to mention it to your healthcare provider, especially if it occurs alongside other symptoms.
8. Shakiness or Tremors
Shakiness or internal tremors can be another surprising symptom of POTS. This may feel like your hands are trembling or like there’s a vibration inside your body.
These tremors are often more noticeable after standing or during periods of anxiety. Relaxation techniques or light exercises can sometimes alleviate this symptom.
9. Excessive Sweating
People with POTS may experience abnormal sweating patterns, such as excessive sweating without exertion or sweating only in certain body areas.
This symptom results from dysfunction in the autonomic nervous system. Monitoring your hydration levels and wearing breathable clothing can help manage excessive sweating.
10. Gastrointestinal Issues
Gastrointestinal symptoms like nausea, bloating, diarrhea, or constipation are common in POTS.
These symptoms often occur because the autonomic nervous system also regulates digestion. Small, frequent meals and staying hydrated can sometimes ease digestive discomfort.
11. Temperature Sensitivity
Many individuals with POTS are sensitive to temperature changes. Hot weather or a warm room can trigger symptoms, while cold temperatures may cause discomfort. Dressing in layers and using cooling devices can help manage temperature sensitivity.
12. Frequent Headaches
Recurring headaches, including migraines, are another common but often overlooked symptom of POTS.
Changes in blood flow or dehydration may cause these headaches. Keeping a headache diary can help you identify potential triggers and patterns.
13. Sleep Disturbances
People with POTS frequently report sleep problems like insomnia, difficulty staying asleep, or non-restorative sleep.
Poor sleep can exacerbate other symptoms, creating a vicious cycle. Sleep hygiene practices, such as maintaining a consistent bedtime routine, can be helpful.
14. Blurred Vision
Blurred vision, especially after standing, is a symptom of POTS, which is linked to reduced blood flow to the eyes.
This can make it difficult to focus on objects or read text. If this happens frequently, talk to your doctor about improving blood circulation.
15. Palpitations
Palpitations, or the sensation of a pounding or irregular heartbeat, are a common and distressing symptom of POTS.
These can occur even when you’re at rest and may be accompanied by chest pain or anxiety. Monitoring your heart rate and staying hydrated can sometimes help manage palpitations.
16. Nausea
Nausea is a frequent complaint among individuals with POTS. It may occur in the morning, after meals, or during periods of standing.
Eating smaller, balanced meals and drinking electrolyte-rich fluids can alleviate nausea for some people.
17. Exercise Intolerance
Many people with POTS struggle with exercise intolerance, finding that even light activity leaves them feeling exhausted or worsens other symptoms.
Slowly building up tolerance under the guidance of a healthcare professional can help improve this over time.
18. Cold or Discolored Extremities
Hands and feet that appear bluish or feel cold to the touch are common in POTS due to poor blood circulation. Compression stockings and elevating your legs can help improve blood flow and reduce discoloration.
19. Frequent Urination
Frequent urination without a clear medical cause is another surprising symptom of POTS. This is thought to be related to the body’s attempt to regulate blood volume. Staying hydrated and tracking fluid intake can help manage this symptom.
20. Anxiety or Panic Symptoms
Feelings of anxiety or panic are often reported in POTS and may be linked to the body’s overactive stress response. It’s important to differentiate between anxiety disorders and POTS-related symptoms to ensure proper treatment.
21. Sensitivity to Light and Sound
Heightened sensitivity to light and sound is a lesser-known symptom of POTS. This can make crowded or noisy environments overwhelming. Sunglasses and noise-canceling headphones are simple tools that can help manage these sensitivities.
FAQs
Q: What causes POTS? A: POTS is a complex condition with various causes, including viral infections, autoimmune disorders, and genetic factors. Research is ongoing to better understand its origins.
Q: How is POTS diagnosed? A: POTS is often diagnosed using a tilt table test, which measures heart rate and blood pressure changes when transitioning from lying down to standing.
Q: Can POTS be cured? A: While there’s no cure for POTS, symptoms can often be managed through lifestyle changes, medication, and physical therapy.
Q: Is POTS a lifelong condition? A: For some, POTS symptoms improve over time, while others may experience it as a chronic condition. Treatment plans are tailored to individual needs.
Q: What’s the difference between POTS and anxiety? A: While POTS can cause symptoms similar to anxiety, such as rapid heart rate and palpitations, it’s rooted in autonomic nervous system dysfunction rather than psychological factors.
Conclusion
Recognizing the diverse symptoms of POTS is crucial for early diagnosis and effective management.
If you’ve identified with several of these symptoms, consider speaking with a healthcare provider to explore the possibility of POTS.
