Renin-Aldosterone Paradox and Perturbed Blood Volume Regulation Underlying Postural Tachycardia Syndrome Satish R. Raj; Italo Biaggioni; Paula C. Yamhure; Bonnie K. Black; Sachin Y. Paranjape; Daniel W. Byrne; David Robertson Background Patients with postural tachycardia syndrome (POTS)...

Abstract Background Many patients with postural orthostatic tachycardia syndrome (POTS) are hypovolemic with plasma volume deficits of 10–30 %. Some also have low levels of aldosterone and diminished aldosterone-renin ratios despite elevations in angiotensin II, pointing to potential adrenal...

Abstract Background High sodium intake is recommended for the treatment of postural tachycardia syndrome (POTS) to counteract the hypovolemia and elevated plasma norepinephrine that contribute to excessive orthostatic tachycardia, but evidence of its efficacy is not available. Objectives This...

Hello Has anyone else any experience of inversion tables? I find them beneficial in a way that I find difficult to explain - general reduction in symptoms and makes me chirpier. I also notice that not using the inversion table seems to have a cumulative bad effect. I have three vague theories...

Multi-System Deconditioning in 3-Day Dry Immersion without Daily Raise Abstract: Dry immersion (DI) is a Russian-developed, ground-based model to study the physiological effects of microgravity. It accurately reproduces environmental conditions of weightlessness, such as enhanced physical...
