Semaglutide for Type 2 Diabetes: Does It Work?
Evidence-based review of Semaglutide's effectiveness for type 2 diabetes, including mechanism of action, dosage context, clinical data, and realistic expectations.
How Semaglutide Addresses Type 2 Diabetes
Semaglutide 1mg (Ozempic) is FDA approved for Type 2 Diabetes with established cardiovascular disease. The SUSTAIN-6 trial showed 26% reduction in MACE. SELECT (2023) showed 20% MACE reduction in overweight/obese patients with cardiovascular disease — the landmark CV trial for the GLP-1 class.
What Semaglutide Is Primarily Used For
- 1.Type 2 diabetes (Ozempic)
- 2.Weight loss/obesity (Wegovy)
- 3.Cardiovascular risk reduction (SELECT trial)
What the Research Shows
Below is a summary of clinical evidence for Semaglutide. Note that not all trials specifically study type 2 diabetes as an endpoint.
Semaglutide 2.4mg produced 14.9% mean weight loss vs 2.4% for placebo over 68 weeks.
Semaglutide reduced major cardiovascular events (MACE) by 20% vs placebo in patients with established cardiovascular disease — a landmark finding leading to expanded use.
Realistic Expectations
Dosage Context for Type 2 Diabetes
Typical range: 0.25–2.4 mg, Once weekly (injectable); once daily (Rybelsus oral)
For Wegovy: Start at 0.25mg weekly, titrate by 0.25mg every 4 weeks up to 2.4mg maintenance dose. For Ozempic: Max dose is 2mg. Oral Rybelsus dose is 3mg daily titrating to 14mg.
Doses for type 2 diabetes may vary from general guidelines. Consult a healthcare provider for condition-specific dosing.
