<b><i>Introduction:</i></b> Despite the abundance of data addressing the influence of patient’s age on surgery-related complications, its impact on cardiometabolic outcomes following bariatric surgery has been overlooked. <b><i>Methods:</i></b> Retrospective unicentric study of 1,728 obese patients who underwent bariatric surgery between January 2010 and June 2015. Patients were divided in 3 age groups, according to their age at surgery: ˂40 (<i>n</i> = 751), 40–59 (<i>n</i> = 879), and ≥60 years (<i>n</i> = 98). Parameters with cardiometabolic impact, such as body anthropometric measures, lipid profile, and glycemic status, before and 24 months after surgery, were compared between these groups. A multiple linear regression was performed, adjusting differences between groups for sex, surgery type, and body mass index variation. <b><i>Results:</i></b> The group ˂40 years presented more weight loss (–35.4 ± 9.0 kg, <i>p</i> ˂ 0.001), greater BMI reduction (–15.8 ± 6.1 kg/m<sup>2</sup>, <i>p</i> ˂ 0.001), and larger changes in waist (–34 ± 13.8 cm, <i>p</i> ˂ 0.001) and hip circumferences (–28.7 ± 11.9 cm, <i>p</i> ˂ 0.05). The group of ≥60 years presented the heaviest reduction in fasting glucose (–17.7 ± 32.8 mg/dL, <i>p</i> ˂ 0.001) and HbA1c (0.7 ± 1.0, <i>p</i> ˂ 0.001), and also had a tendency to have the biggest changes in systolic blood pressure (–14.7 ± 18.7 mm Hg, <i>p</i> = 0.071). <b><i>Conclusion:</i></b> Patients with ≥60 years benefit the most from bariatric surgery regarding cardiometabolic parameters, presenting heavier reductions in fasting glucose, as well as HbA1c and a tendency towards a higher decrease in systolic blood pressure. No clinically significant differences in lipid profile were observed between groups.
