GIP signaling is selectively impaired in type 2 diabetes, reducing its insulinotropic effect, while GLP-1 signaling remains substantially preserved.
In Type 2 Diabetes, your body's natural response to GIP is blunted, which is why GLP-1 based medications are often more effective for stimulating insulin than therapies targeting GIP.

Critically, the effects of infused GIP at pharmacological levels are impaired in Caucasians with T2DM, although those of GLP-1 are substantially preserved.

- 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
