Having diabetes means that your blood sugar is too high. Sugar, or glucose, is the basic source of fuel for many of the body's organs. Insulin is a hormone produced by the pancreas that allows sugar to move from the blood into the cells, where it can be used for energy. Two Types of Diabetes
People with type 1 diabetes do not make insulin at all. Only 5 to 10 percent of all people with diabetes have type 1 diabetes. Type 2 diabetes is far more common, accounting for 90 to 95 percent of all cases. When you have type 2 diabetes, your body has two problems with insulin:
Your pancreas doesn't make enough of it
Your body has a hard time using it.
As a result, the amount of sugar in your blood isn't properly managed. Blood sugar levels are especially hard to control after mealtimes, when they are prone to surges, or "spikes." Over time, elevated blood sugar levels begin to cause problems with other tissues in the body.
