Eli5: How diabetes work and how insulin helps diabetics?
In: 5
Insulin levels are (and this is an oversimplification) signals your body uses to regulate how much sugar is in your blood.
When your blood sugar is high, the body releases insulin. This chemical helps the body’s cells absorb and use the sugar. This brings the blood sugar levels down to more manageable levels.
Diabetics either have a resistance to insulin (Type 2) or have a condition that prevents them from producing it (Type 1). Without insulin, blood sugars can get dangerously high.
