Here is some information i copied for you on diabetes, better for you to read this then for me to try and explain
a problem in the way your body makes or uses insulin. Insulin is
needed to move glucose (blood sugar) into cells, where it is used for energy.
If glucose does not get into the cells, the body cannot use it for energy. Too much glucose will then remain in the blood, causing the symptoms of diabetes.
There are several types of diabetes.
