Unlike people with type 1 diabetes, people with type 2 diabetes produce insulin; however, the insulin their pancreas secretes is either not enough or the body is unable to recognize the insulin and use it properly. This is called insulin resistance. When there isn't enough insulin or the insulin is not used as it should be, sugar (glucose) can't get into the body's cells to be used for fuel. When sugar builds up in the blood instead of going into cells, the body's cells are not able to function properly. Other problems associated with the build up of sugar in the blood include:

The higher level means your body is starting to have trouble using the hormone insulin, which normally moves glucose from the blood into your body's cells. Without insulin working properly, glucose...
Dehydration. The build up of sugar in the blood can cause an increase in urination (to try to clear the sugar from the body). When the kidneys lose the sugar through the urine, a large amount of water is also lost, causing dehydration.
