Dysautonomia and Postural Orthostatic Tachycardia Syndrome: A Critical Analysis of Dysautonomia: How to Diagnose and Treat.

A significant number of physicians are unclear of the vast clinical manifestations of dysautonomia and imbalance of the autonomic nervous system, specifically the parasympathetic and sympathetic nervous systems. The major obstacle has been an inability to determine the mechanism of action as well as multisystem dysfunction and a lack of clear-cut testing. Dysautonomia, a pathophysiological malfunction of the sympathetic and parasympathetic nerves in our bodies, can present as altered clinical functions of heart rate (tachycardia/bradycardia), altered breathing patterns, blood pressure (hypertension/hypotension), sweating, digestion, syncope, etc.

Metabolomic comparison of postprandial distress syndrome patients with and without duodenal eosinophilia.

Objective: In functional dyspepsia patients, duodenal mucosal eosinophilia has been associated with early satiety but is not present in all patients suggesting varied pathways to symptom generation. The objective of the current study was to explore metabolic differences comparing those with duodenal mucosal eosinophilia to those without eosinophilia.

Methods: This study was conducted utilizing an existing biorepository.
