Insulin is a crucial hormone produced by the pancreas that plays a vital role in regulating blood sugar levels. When you eat, your body breaks down carbohydrates into glucose, which enters your bloodstream. Insulin helps cells absorb glucose, using it for energy or storing it for future use. This process keeps your blood sugar levels stable.

For people with diabetes, their bodies either don't produce enough insulin or can't use it effectively, leading to high blood sugar levels. This is why insulin therapy can be essential for managing diabetes, helping mimic the natural insulin response to maintain normal blood sugar levels. If you have any specific questions about insulin or its role in the body, feel free to ask!
