Possible Causes of Brain Fog, Dizziness and Nausea in POTS with Dr. Cathy Pederson

In this episode, Dr. Cathy Pederson discusses the potential causes of common POTS symptoms such as brain fog, dizziness, nausea, and fainting. She highlights the role of systemic inflammation, anemia, thyroid issues, and hormonal changes in contributing to brain fog, and suggests potential areas for investigation with a doctor. The discussion also covers dizziness and fainting, often linked to poor circulation and blood pooling in the abdomen due to orthostatic intolerance. Poor blood volume regulation, especially after meals, may exacerbate these issues. Dr. Pederson suggests lifestyle modifications like gradual posture changes, proper hydration with electrolytes, and reduced carbohydrate intake to manage symptoms. The episode underscores the complexity of these symptoms, emphasizing blood flow issues as a common underlying theme, and highlights ongoing research into potential neurological and physiological mechanisms, such as the role of the vagus nerve. Practical advice for symptom management, including medications and lifestyle adjustments, is provided for patients and caregivers.
