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:
Even before you notice symptoms, high blood sugar can damage parts of your body. That's why certain diabetes tests to check blood sugar control and to catch problems early are so crucial.
But many patients aren't getting key diabetes tests at least annually, such as the hemoglobin A1c test, a dilated eye exam, and a foot exam.
"If you look at the nationwide data, it's sobering," says Enrico Cagliero, MD, a diabetes researcher and assistant professor of medicine at Harvard Medical School. "A lot...
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.
