Often Overlooked Signs and Symptoms of POTS

Wix Media

Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the autonomic nervous system, causing an abnormal increase in heart rate when standing up. While many people recognize the classic symptoms like rapid heartbeat and dizziness, several signs often go unnoticed or misunderstood. These overlooked symptoms can delay diagnosis and treatment, impacting quality of life.

POTS is a disorder that disrupts the body's ability to regulate blood flow and heart rate upon standing. The most well-known symptom is a rapid heartbeat, but the syndrome affects multiple body systems. Because symptoms vary widely and overlap with other conditions, many patients and even healthcare providers miss or misinterpret them.

Symptoms that seem unrelated to heart rate or blood pressure changes may not immediately suggest POTS. This leads to frustration for patients who feel their concerns are dismissed or misunderstood. Recognizing the full range of symptoms is crucial for timely diagnosis and effective management.

Because POTS affects the Autonomic Nervous System, the ANS controls all the bodily functions that are involuntary. The ANS manages heart rate, blood pressure, breathing, digestion, body temperature, metabolism, urination, and sexual response.

The ANS is regulated by the brain which allows it to adapt to stress or maintain a restful state according to the situation it perceives.

Commonly Overlooked Symptoms of POTS

1. Brain Fog and Cognitive Difficulties

Many people with POTS experience problems with concentration, memory, and mental clarity. This "brain fog" can feel like confusion, difficulty focusing, or forgetfulness. It often worsens when standing or during physical activity.

This symptom is frequently mistaken for anxiety, depression, or stress-related issues. However, brain fog in POTS results from reduced blood flow to the brain when upright, affecting cognitive function.

2. Gastrointestinal Issues

Digestive problems such as nausea, bloating, abdominal pain, and diarrhea are common but often overlooked symptoms. These occur because POTS can affect the autonomic nerves that control digestion.

Patients may report feeling full quickly, experiencing frequent stomach upset, or having irregular bowel movements. These symptoms can be mistaken for irritable bowel syndrome or food intolerances, delaying proper diagnosis.

3. Temperature Regulation Problems

People with POTS often struggle to maintain a stable body temperature. They may feel excessively hot or cold, sweat abnormally, or have cold extremities even in warm environments.

This happens because the autonomic nervous system also controls sweat glands and blood vessel constriction. Temperature regulation issues are rarely linked to POTS unless specifically investigated.

4. Fatigue Beyond Normal Tiredness

While fatigue is a common complaint in many chronic illnesses, POTS-related fatigue is often severe and persistent. It can feel like an overwhelming lack of energy that does not improve with rest.

This fatigue is linked to poor blood circulation and oxygen delivery to muscles and organs. It can interfere with daily activities and is sometimes mistaken for chronic fatigue syndrome or depression.

5. Sleep Disturbances

Many individuals with POTS report problems falling asleep, staying asleep, or experiencing non-restorative sleep. Sleep issues may worsen symptoms during the day, creating a cycle of exhaustion.

Sleep disturbances in POTS may be caused by autonomic dysfunction affecting breathing patterns or by pain and discomfort related to the condition.

Recognizing these often missed symptoms can help patients seek appropriate care sooner. Early diagnosis allows for better symptom management and improved quality of life. It also helps avoid unnecessary tests and treatments for other conditions.

For example, a patient with unexplained brain fog and digestive issues might not connect these to POTS unless a healthcare provider considers the full symptom picture. Awareness of these signs encourages a more comprehensive evaluation.

Practical Tips for Managing Overlooked Symptoms

• Track your symptoms: Keep a detailed diary of all symptoms, including those that seem unrelated to heart rate or dizziness. Note when they occur and what makes them better or worse.

• Communicate clearly with your healthcare provider: Share your full symptom list and how they affect your daily life. This helps your provider understand the scope of your condition.

• Manage fatigue: Prioritize rest and avoid overexertion. Gentle, paced exercise under medical guidance can improve circulation without worsening fatigue.

• Address digestive symptoms: Small, frequent meals and hydration can ease gastrointestinal discomfort. Consult a dietitian if needed.

• Improve sleep hygiene: Establish a regular sleep schedule, create a comfortable environment, and avoid stimulants before bedtime, sleep in a dark, quiet room.

• Stay well hydrated: Typically 2-3 liters of fluid a day to help prevent blood pooling

• High Salt Intake: Salt helps expand blood volume and prevents water from being eliminated quickly recommended is 3,000-10,000mg daily

• Low impact Isometric exercises: to help improve overall stability and orthostatic tolerance.

  
  

When to Seek Medical Advice

If you experience rapid heartbeat upon standing along with any of the symptoms described here, consider consulting a healthcare professional familiar with autonomic disorders. A thorough evaluation may include heart rate and blood pressure monitoring, tilt table testing, and blood tests.

Early recognition and diagnosis of POTS can lead to better symptom control and reduce the risk of complications.
