[A simple miracle of water]

Abstract

Chronic orthostasis intolerance or postural tachycardia syndrome (POTS) is a common problem, which is related to the more severe forms of autonomic neuropathy. Upright posture regularly elicits uncomfortable symptoms in these patients, which impairs their quality of life. We present a typical case, where orthostatic hemodynamic response was significantly improved by ingestion of 500 ml tap water. This simple measure could be a potent, long-term therapeutic tool.
