Endogenous GLP-1 and GIP hormones play a critical role in cardiovascular physiology, with GLP-1 promoting cardioprotection through anti-apoptotic signaling and improved glucose utilization, while GIP's role is complex and species-dependent.
Your body naturally produces hormones called GLP-1 and GIP that help protect your heart and blood vessels. GLP-1 improves blood flow, reduces inflammation, and helps your heart use energy efficiently during stress. GIP also plays a role in metabolism and heart health. Understanding these natural pathways helps explain why medications that mimic them are so effective for heart health.
Endogenous GLP-1 promotes insulin secretion, β-cell survival, and appetite suppression, and exerts protective effects on the endothelium. GLP-1 also reduces inflammation, enhances nitric oxide production, and improves myocardial glucose utilization during ischemia. Endogenous GIP is involved in insulin secretion, β-cell survival, and adipogenesis.

- 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
