Intraindividual Variability in Orthostatic Blood Pressure Changes Among Older Adults: The Influence of Meals

Abstract

Because of the variability of postural BP changes, the diagnosis of OH should not be based on a single orthostatic BP measurement but requires repeated testing, at best under circumstances similar to those in which the symptoms occurred. The postprandial period is not particularly favorable to OH, suggesting that the ingestion of a meal does not worsen orthostatic BP changes in most aged patients.
