Metabolic targets in the Postural Orthostatic Tachycardia Syndrome: A short thematic review.

Abstract

Postural Orthostatic Tachycardia Syndrome (POTS) is a chronic autonomic condition hallmarked by orthostatic intolerance and tachycardia in the upright position. POTS impacts approximately 1-3 million people in the U.S. alone, in which the majority of patients are premenopausal women. The etiology of POTS is multi-factorial with three primary clinical subtypes, including neuropathic, hyperadrenergic, and hypovolemic POTS. Recent evidence suggests potential metabolic associations with POTS pathophysiology, particularly involving insulin resistance and abnormal vasoactive gut hormones. This review aims to characterize POTS phenotypes and explore potential metabolic links, focusing on insulin resistance and vasoactive gut hormones. Understanding the metabolic aspects of POTS pathophysiology could provide novel insights into its mechanisms and guide therapeutic approaches.
