Semaglutide demonstrates superior efficacy compared to Dulaglutide in reducing both HbA1c and Fasting Blood Sugar (FBS), but shows no significant difference in weight loss or BMI reduction.
If you are using Dulaglutide and your blood sugar (HbA1c and FBS) is not well-controlled, switching to Semaglutide may offer better glycemic results. However, if your primary goal is weight loss, switching is unlikely to yield additional weight reduction compared to staying on Dulaglutide.

In comparison to Dulaglutide, Semaglutide displayed superior efficacy in reducing HbA1c levels (3.72; 95% CI: 0.02–7.41; p = 0.05) and FBS (2.66; 95% CI: 0.26–5.07; p = 0.03). However, no significant differences were found in weight and BMI change.
