Blood glucose (blood sugar) is your body's main source of energy It is controlled by insulin, a hormone made by the pancreas. Insulin allows your body to use glucose from the food that you eat for energy or to store glucose for future use. Insulin helps keep your glucose level from getting too high or too low. If your body doesn’t produce enough insulin, or if your cells don’t respond to insulin, you may end up having too much glucose in your blood. Over time high levels of glucose cause diabetes
Type 1 Diabetes:
People with type 1 diabetes have an immune system that attacks and destroys the cells in the pancreas that make insulin. This results in the pancreas making little or no insulin, requiring that those with type 1 diabetes take insulin to live. Type 1 diabetes develops most often in young people but can also appear in adults.
Type 2 Diabetes:
If you have type 2 diabetes, your body is “insulin resistant,” which means it doesn’t use insulin properly. Over time, the pancreas can’t make enough insulin to keep your glucose at normal levels. This type of diabetes can happen at any age and is the most common form of diabetes.
