CAlgary SAlt for Postural Orthostatic Tachycardia Syndrome (CASA-POTS)

Summary

This study will evaluate high-salt compared to moderate-salt over a period of about 3 months. The purpose of this study is to see if increasing the amount of salt in the diet will reduce heart rate and symptoms in patients with POTS when compared to placebo (cellulose pill). To do this, we are conducting a randomized-clinical trial looking at a high-salt diet compared to a moderate-salt diet. This is a cross-over study, meaning that participants will do both the high-salt and moderate-salt components of the study. The study will have three in lab evaluations as well as online surveys.
