A importância da hemoglobina glicada no diagnóstico e acompanhamento do paciente diabético

Abstract

ABSTRACT: This study addresses glycated hemoglobin (HbA1c) as an essential tool for monitoring glycemic control in patients with diabetes. The high prevalence of the disease and the impact of its complications make the use of accurate markers indispensable for guiding clinical decisions and preventing adverse outcomes. OBJECTIVE: to analyze the applicability of HbA1c as a parameter for evaluating glycemic control and to discuss its relevance in preventing complications and guiding individualized therapeutic adjustments. METHODOLOGY: this is a qualitative and descriptive literature review conducted in databases such as SciELO, PubMed, and Google Scholar, including articles published between 2018 and 2025, using the descriptors “glycated hemoglobin,” “HbA1c,” “glycemic control,” “diabetes mellitus,” and “diabetic complications.” RESULTS : HbA1c reflects the average blood glucose levels of the previous months, does not require fasting, and assists in risk stratification. Elevated values are associated with a higher incidence of retinopathy,

nephropathy, and cardiovascular diseases. FINAL CONSIDERATIONS : HbA1c is a reliable marker, essential in biomedical practice and public health, contributing to early interventions and reduction of chronic complications.
