People who have multiple autoantibodies related to type 1 diabetes but still have normal blood sugar levels show lower levels of the hormone GIP after consuming glucose, compared to those with only one such autoantibody. This difference may reflect an early disruption in the hormonal pathway that helps stimulate insulin release.

People who have multiple autoantibodies targeting their pancreatic islets but still have normal blood sugar levels show a 45% decrease in the hormone response that helps regulate insulin after eating, along with lower levels of the GIP hormone during a glucose test, indicating early metabolic changes before diabetes develops.

After eating a high-fat, low-carb diet for three days, the body releases more of a gut hormone called GLP-1 when you drink sugar water — even though blood sugar goes higher.

In people who have antibodies indicating early risk for type 1 diabetes but still have normal blood sugar, a decrease in the hormone GIP—compared to GLP-1—appears to be the main reason for reduced insulin response after eating, which may make GIP a better early indicator of pancreatic beta-cell stress.
