What Happens When You Have Diabetes?
When you have diabetes, your body can't properly use the energy from the food you eat. This problem is closely tied to how your body makes and uses insulin.
Insulin is a substance made in your pancreas (an organ in your body) that helps to keep your blood sugar (glucose) within normal range unless you have diabetes.
Type 1 vs. Type 2 Diabetes
In both types of diabetes, sugar builds up in your bloodstream because it cannot enter the cells.
- In type 1 diabetes, your body makes little or no insulin. This is called insulin deficiency
- In type 2 diabetes, your body makes insulin, but your cells do not use it as effectively as they should. This is called insulin resistance. Also, your ability to make insulin can gradually decrease as time goes by
- Without sugar for fuel in the cells, your body lacks energy
- Sugar stays in your blood and you have high blood sugar levels
- Blood sugar levels that are too high can damage your blood vessels, and over a long period of time can result in serious complications
