What Is Insulin and Why Do Some People Need It?

What is Insulin?

Insulin is a special protein made in our body that helps turn the food we eat into energy!

How Does Insulin Work?

Think of insulin like a key that unlocks your body's cells to let sugar in for energy.

Where Does Insulin Come From?

It's made by the pancreas, an organ near your stomach.

Without insulin, sugar stays in our blood and can't get into cells to power our body.

What Happens Without Insulin?

Some people's bodies can't make enough insulin, so they need to get it from medicines.

Who Needs Extra Insulin?

Types of Diabetes

People who need extra insulin often have a condition called diabetes.

Type 1 Diabetes

In Type 1 diabetes, the pancreas makes very little or no insulin.

Type 2 Diabetes

In Type 2 diabetes, the body doesn't use insulin well and sometimes needs extra.

Insulin can't be taken as a pill. People take it through injections or a small pump.
