Subcutaneous semaglutide (0.5-1.0 mg) and oral semaglutide (14 mg) effectively reduce body weight and HbA1c in patients with Type 2 Diabetes, with subcutaneous administration showing greater weight loss than oral administration in indirect comparisons.
For patients with Type 2 Diabetes, both subcutaneous (0.5-1.0 mg weekly) and oral (14 mg daily) semaglutide effectively reduce weight and blood sugar. Subcutaneous administration appears to produce greater weight loss than the oral form, though both are superior to other diabetes medications.
StrongSupportsHIGH confidence
Based on the analysis of 10 studies... it was found that semaglutide more effectively reduced the level of glycated hemoglobin (HbA1c), as well as the body mass of the subjects compared to placebo... However, in indirect comparison of results... we found that subcutaneous administration of semaglutide led to greater weight loss than oral.
Why this rating
Based on multiple Phase 3 RCTs (SUSTAIN 1-10, PIONEER 1-10).

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
