May reduce sodium excretion with upright posture in orthostatic hypotension; leaves open mechanisms and long-term management implications.
Does assuming the upright posture affect renal excretion of sodium and chloride in patients with orthostatic hypotension?
Upright posture in patients with orthostatic hypotension leads to decreased sodium and chloride excretion due to both decreased filtered load and changes in tubular reabsorption.
Bachman et al. (1953) studied this question.
