Group 2: from 5.78 ± 0.75% to 5.17 ± 0.54% (mean decrease: 0.61 ± 0.28%, p< 0.001). BMI decreased by 5.36 ± 3.45 kg/m² in Group 1 and 4.41 ± 4.63 kg/m² in Group 2 (p< 0.0001), with greater reduction in Group 1 (p=0.017). Gastrointestinal adverse effects were most common, including nausea, vomiting, constipation, gastritis, and diarrhea, with higher incidence in Group 1. HbA1c reduction correlated with baseline HbA1c, age, and gender; BMI reduction correlated with baseline HbA1c and BMI.Conclusion: Semaglutide was more effective than liraglutide in reducing HbA1c and BMI. Gastrointestinal symptoms were the most frequent side effects in both groups.Keywords: GLP-1 receptor agonist, semaglutide, liraglutide, obesity, type 2 diabetes
