Surprising Things You Didn''t make enough insulin or your body doesn''t produce enough of this hormone. Type 2 diabetes gradually makes it harder for your beta cells to work, and also makes all the cells of your body less able to pull in and use insulin.
In both types of diabetes, sugar from the foods you eat builds up in your blood. Constantly having high blood sugar damages your blood vessels. Over time, diabetes can cause problems with your nerves, eyes, kidneys, heart, and other organs.
Everyone with type 1 diabetes and some people with type 2 diabetes take a lab-made form of insulin to control their blood sugar.
How Insulin Treatment Helps Your Blood Sugar
Insulin treatment works in much the same way as natural insulin that the pancreas makes. After you eat, your body breaks down carbohydrates into glucose. That glucose goes into your bloodstream and causes your blood sugar level to rise.
When you take insulin, it helps to move glucose out of your bloodstream and into cells. Your cells use some of that sugar for energy and then store any leftover sugar in your fat, muscles, and liver for later.
Once the sugar moves into your cells, your blood glucose level should go back to normal.
