Three Types of POTS with Dr. Cathy Pederson

In this episode, Dr. Cathy Pederson discusses the three subtypes of Postural Orthostatic Tachycardia Syndrome (POTS): hyperadrenergic, neuropathic, and hypovolemic. Each subtype is characterized by distinct underlying mechanisms, symptoms, and potential treatments. Hyperadrenergic POTS involves an abnormal increase in norepinephrine levels, neuropathic POTS is associated with damage to the small fibers of the autonomic nervous system, and hypovolemic POTS is characterized by low blood volume. Dr. Pederson elaborates on the common symptoms associated with each subtype and suggests both pharmacological and nonpharmacological treatments that may be beneficial. The discussion also includes insights on recognizing symptoms to aid in identifying which subtype of POTS a patient may have, thereby guiding more targeted management strategies.
