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:
Don White, 68, a retired science teacher from upstate New York, first suspected he had type 2 diabetes when he was 45 years old and his school held a health fair for students and teachers. A simple prick of his finger to test for high blood sugar -- a sign of diabetes -- revealed some unexpected news.
"My numbers were way above normal," says White. "In a matter of days, and a couple of doctor's appointments later, I found out I had type 2 diabetes."
White and his family were surprised by the diagnosis...
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.
