GLP-1 receptor agonists (GLP-1 RAs) including dulaglutide, subcutaneous semaglutide, and oral semaglutide produce significant weight loss and BMI reduction in patients with type 2 diabetes and obesity, with oral semaglutide achieving the highest proportion of patients reaching the clinically significant ≥5% weight loss threshold.

GLP-1 medications like dulaglutide and semaglutide (oral and injectable) are effective for weight loss in people with type 2 diabetes and obesity. In this study, about half of the patients lost at least 5% of their body weight in just 3 months. Oral semaglutide was the most effective at getting patients to this 5% threshold. However, gastrointestinal side effects are common, and many patients do not reach the maximum dose. If you tolerate the medication, reaching the maximum dose is linked to better weight loss results. Consult your doctor about titration to maximize benefits.

GLP1 RA significantly reduced body weight (−4.95 kg, p < 0.001) and BMI (−1.86 kg/m2, p < 0.001)... Oral semaglutide achieved the highest reduction: 61.1 % of patients achieving ≥ 5 %, subcutaneous semaglutide 45.8 % and dulaglutide 40.6 %.
