Once-weekly subcutaneous semaglutide 2.4 mg induces significant weight loss (average 14.9% body weight) in non-diabetic adults with overweight or obesity compared to placebo.

If you have obesity and do not have diabetes, a once-weekly injection of semaglutide (2.4 mg) is a highly effective medical treatment that can lead to an average 15% reduction in body weight over 16 months. This is significantly more effective than placebo and addresses the biological drive to regain weight that often limits lifestyle changes alone.
