What is DPP-4?

DPP-4 is like a gatekeeper that helps control how much sugar we have in our blood.

Imagine your body has tiny workers called glucagon-like peptide-1 (GLP-1). These workers help tell your body when to use sugar and when to store it. But there's another worker, called DPP-4, who acts like a gatekeeper, whenever GLP-1 comes through the gate, DPP-4 sometimes stops it from doing its job.

Think of it like this: you're eating a big cookie (that’s sugar), and your body wants to know how much sugar is coming in. The GLP-1 workers are trying to help you manage that sugar, but if DPP-4 is busy, it might stop them from doing their job properly.

Now imagine DPP-4 is like a kid who loves to play hide-and-seek and sometimes forgets to let the GLP-1 workers in. That means your body might not know exactly how much sugar you're eating, and that can cause blood sugar levels to go up or down more than they should.

If we can help DPP-4 be a better gatekeeper, or stop it from stopping GLP-1 so often, our bodies can manage sugar more easily. That’s why sometimes doctors use medicines that block DPP-4, so the GLP-1 workers can keep doing their job!
