Serum and Urinary Sodium Levels in Obese Patients with Essential Arterial Hypertension
Keywords:
obesity; arterial hypertension; serum/urinary sodium.Abstract
Introduction: Obesity has been considered the most significant risk factor for elevated blood pressure levels.
Objective: To describe serum and urinary sodium levels in obese patients with essential arterial hypertension.
Methods: A case series study was conducted involving patients from Máximo Gómez Báez Polyclinic in Holguín, covering the period from July 4, 2022, to July 4, 2023. The sample consisted of 155 patients; anthropometric measurements were taken, laboratory tests (serum and urinary sodium) were performed, and data were extracted from individual medical records.
Results: Serum sodium levels were elevated in 72.26 % of patients, whereas urinary sodium levels remained within normal range in 76.13 %. The most represented age group was 60 years and older, accounting for 38.71 % of the sample. Statistical significance was observed for Grade III obesity and Grade III arterial hypertension, particularly in cases with a longer duration since diagnosis.
Conclusions: Elevated blood sodium levels were observed, whereas urinary sodium levels remained normal. These findings correlated with the age group of 60 years and older, in which obesity and arterial hypertension were classified as Grade III, and where hypertensive disease had been diagnosed more than five years prior.
