Abstract
Proper hydration is essential to maintain optimal health and well-being at all stages of life, especially for the elderly. Side effects of certain drugs that affect hydration status may compromise the health of the ancients, who also constitute the most vulnerable group. No studies have been carried out, to our knowledge, at the intersection of drugs and hydration status. Our study aimed to evaluate the effects of chronic use of certain drugs (diuretics, corticoids and metformin) in the hydration status of the elderly. Results were obtained from a cross-sectional study with 96 volunteers (65–93 years) selected based on their pharmacological treatment. It included a validated food and drink frequency questionnaire and water removal, dehydration signs and symptoms assessment and urine analysis. All data were analysed by age and sex. Water balance decreased with advanced age, especially in men’s group. Results were confirmed by means of the evaluation of dehydration signs and symptoms and colorimetric and chemical analysis of urine. Correlations between consumption of corticoids and hydration status were found, with different signs depending on the administration route (Rho = 0.522 and Rho = − 0,522 for oral and pulmonary corticoids, respectively). Furthermore, correlations between diuretics (Rho = − 0.343, p < 0.05) and metformin (Rho = − 0.802, p < 0.01) consumption and different urine markers were determined. In conclusion, the predominant dehydration state of the volunteers of the study is affected by drugs consumption and their route of administration. Hence, there is an urgent need for monitorization of hydration status based on drugs consumption.
