Hormonal

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.
