Diabetes mellitus type 1 According to the current definition, two fasting glucose measurements above 126 mg/dl (7.0 mmol/l) is considered diagnostic for diabetes mellitus. In type 1, pancreatic beta cells in the islets of Langerhans are destroyed, decreasing endogenous insulin production. This distinguishes type 1's origin from type 2. Type 2 diabetes is characterized by insulin resistance, while type 1 diabetes is characterized by insulin deficiency, generally without insulin resistance. Another hallmark of type 1 diabetes is islet autoreactivity, which is generally measured by the presence of autoantibodies directed towards the beta cells. The appearance of diabetes-related autoantibodies has been shown to be able
The Environmental Determinants of Diabetes in the Young The Environmental Determinants of Diabetes in the Young The Environmental Determinants of Diabetes in the Young is a longitudinal study examining the environmental causes of Type 1 diabetes(T1D), formerly known as juvenile diabetes. The study follows children at high genetic risk for T1D from birth to 15 years of age. Although genetic markers for Type 1 Diabetes have been identified, genetic predisposition is not the only factor in development of the disease. An increasing body of evidence, including rising rates of T1D diagnosis and incomplete penetrance of the disease in genetically predisposed individuals, suggests that environment may play an equally
