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, and nausea. Brain fog in POTS patients may be linked to factors like systemic inflammation, anemia, or thyroid issues. Dizziness and lightheadedness often result from poor circulation and low blood volume, exacerbated when standing due to gravity's effect on blood pooling. Medications and inner ear issues might also contribute. The episode explores potential mechanisms, including the role of the vagus nerve in fainting. For nausea, the dysfunction in the autonomic nervous system affects the enteric nervous system, causing issues like gastroparesis. Strategies for managing these symptoms include sitting down when dizzy, having smaller meals to manage postprandial hypotension, and adjusting diet to reduce carbohydrates. Dr. Pederson emphasizes trial and error in finding effective management strategies for these symptoms.
