![]() This assessment method is often cited in the literature as the gold-standard for measuring hydration status, 6,9 although some authors raise important concerns regarding this method. Some of the methods attempt to compare the sizes of the individual compartments, other rely on biomarkers estimating the concentration of the solutes found in bodily fluids, or attempt to assess the hydration status using the physiological signs and symptoms. ![]() 8Īssessment techniques aim to measure one or more fluid compartments either directly or indirectly. There have been numerous attempts to establish the most reliable assessment method that could be used for different population groups, 1-7 but so far the superiority of any one of these has not been established. Many assessment methods exist, and these were established for different purposes such as clinical, academic or industrial settings. Water balance is a continuous process of water losses from kidneys, lungs and skin and occasional uptake through oral intakes. Measuring hydration status is challenging due to complex dynamics associated with fluid regulation. Methods of Assessment of Hydration Status and their Usefulness in Detecting Dehydration in the Elderly. Curr Res Nutr Food Sci 2017 5(2).īak A, Tsiami A, Greene C.

Since many experts argue that there is no 'gold-standard' technique and one can never be achieved, this paper describes both, the benefits and limitations of the available methods and their usability in assessing hydration status of the elderly. Different techniques have been developed to determine hydration status for the use in clinical settings, but their diagnostic accuracy remains questionable. Few assessment methods have been validated to accurately measure the fluid compartments in the body, but they have little application in practice. Assessment of hydration status is complex and difficult to achieve.
