GLP-1 receptor agonists and DPP-4 inhibitors provide effective glucose lowering with weight loss (GLP-1) or weight neutrality (DPP-4) and minimal hypoglycemia risk, outweighing potential risks of pancreatitis or thyroid cancer which lack convincing human evidence.

For patients with Type 2 Diabetes, GLP-1 receptor agonists (like liraglutide or exenatide) and DPP-4 inhibitors (like sitagliptin) are effective, safe options for lowering blood sugar. GLP-1 agonists offer the added benefit of weight loss, while DPP-4 inhibitors are weight-neutral. Current evidence does not support fears of increased pancreatitis or thyroid cancer risk in humans, making these therapies favorable compared to older drugs that cause weight gain or hypoglycemia.

GoodSupportsHIGH confidence
The benefits by far outweigh the potential risks... Glucagon-like peptide 1 (GLP-1) receptor agonists demonstrate an efficacy comparable to insulin treatment and appear to do so with significant effects to promote weight loss with minimal hypoglycemia... there are significant data with dipeptidyl peptidase 4 (DPP-4) inhibitors showing efficacy comparable to sulfonylureas but with weight neutral effects and reduced risk for hypoglycemia.

Why this rating

Based on extensive clinical trial data, meta-analyses, and long-term human experience, though some long-term cancer risks remain under investigation.
