Diabetes Control and Complications Trial (DCCT):
a study by the National Institute of Diabetes and Digestive and Kidney Diseases, conducted from 1983 to 1993 in people with type 1 diabetes. The study showed that intensive therapy compared to conventional therapy significantly helped prevent or delay diabetes complications. Intensive therapy included multiple daily insulin injections or the use of an insulin pump with multiple blood glucose readings each day. Complications followed in the study included diabetic retinopathy , neuropathy , and nephropathy.
a health care professional who teaches people who have diabetes how to manage their diabetes. Some diabetes educators are certified diabetes educators .
a condition characterized by frequent and heavy urination, excessive thirst, and an overall feeling of weakness. This condition may be caused by a defect in the pituitary gland or in the kidney. In diabetes insipidus, blood glucose levels are normal.
a condition characterized by hyperglycemia resulting from the body's inability to use blood glucose for energy. In type 1 diabetes, the pancreas no longer makes insulin and therefore blood glucose cannot enter the cells to be used for energy. In type 2 diabetes, either the pancreas does not make enough insulin or the body is unable to use insulin correctly.
Diabetes Prevention Program
a study by the National Institute of Diabetes and Digestive and Kidney Diseases conducted from 1998 to 2001 in people at high risk for type 2 diabetes. All study participants had impaired glucose tolerance , also called pre-diabetes , and were overweight. The study showed that people who lost 5 to 7 percent of their body weight through a low-fat, low-calorie diet and moderate exercise (usually walking for 30 minutes 5 days a week) reduced their risk of getting type 2 diabetes by 58 percent. Participants who received treatment with the oral diabetes drug metformin reduced their risk of getting type 2 diabetes by 31 percent.

KEY-toe-ass-ih-DOH-sis) y condition in which extremely high blood glucose levels , along with a severe lack of insulin , result in the breakdown of body fat for energy and an accumulation of ketones in the blood and urine. Signs of DKA are nausea and vomiting, stomach pain, fruity breath odor, and rapid breathing. Untreated DKA can lead to coma and death.

the process of cleaning wastes from the blood artificially. This job is normally done by the kidneys. If the kidneys fail, the blood must be cleaned artificially with special equipment. The two major forms of dialysis are hemodialysis and peritoneal dialysis.hemodialysis (HE-mo-dy-AL-ih-sis):the use of a machine to clean wastes from the blood after the kidneys have failed. The blood travels through tubes to a dialyzer (DY-uh-LY-zur), a machine that removes wastes and extra fluid. The cleaned blood then goes back into the body. peritoneal (PEH-rih-tuh-NEE-ul) dialysis: cleaning the blood by using the lining of the abdomen as a filter. A cleansing solution called dialysate (dy-AL-ih-sate) is infused from a bag into the abdomen. Fluids and wastes flow through the lining of the belly and remain "trapped" in the dialysate. The dialysate is then drained from the belly, removing the extra fluids and wastes from the body.
