About Type 2 Diabetes

Management of blood glucose levels and insulin sensitivity in type 2 diabetes.

Research Evidence

STEP trials: 15-17% weight loss. FLOW trial: 24% reduction in kidney disease progression (Jan 2025 approval). Wegovy pill: 16.6% weight loss (Dec 2025 approval). Oral Rybelsus approved for CV risk reduction (Oct 2025). In January 2025, Ozempic received FDA approval for reducing kidney disease progression in T2D patients with CKD. In March 2026, Wegovy HD (7.2mg) was approved, delivering 20.7% mean weight loss — the highest for any injectable semaglutide dose.
