The Two Hormones Behind Every Blood Sugar Number

Most conversations about diabetes focus entirely on insulin, but blood sugar is actually controlled by two hormones working in opposite directions. Understanding the function of insulin and glucagon together, not separately, is the real key to understanding what's happening in your body.

What Insulin Does

Insulin is released when blood sugar rises. Its job is to move glucose out of your bloodstream and into your cells. In Type 2 diabetes, cells stop responding properly to insulin.

What Glucagon Does

Glucagon does the opposite job. When blood sugar drops too low, your pancreas releases glucagon, which signals your liver to release stored glucose back into the bloodstream.

Insulin vs Glucagon Function: Why Balance Matters

Insulin vs glucagon function isn't really a competition, it's a balance. In Type 2 diabetes, this balance breaks down on both sides, not just insulin resistance.

How Insulin and Glucagon Work Together in Practice

How insulin and glucagon work together determines your entire day's blood sugar pattern. This is exactly why BBDO's 5-Finger Punch approaches blood sugar holistically.
