Type 2 diabetes develops much quicker in children than it does in adults, according to a US study.
Research shows that insulin doses for children need to be raised within two years of the disease being diagnosed, indicating a faster beta-cell function decline than seen in adults with type 2 diabetes.
Lorraine Katz, who led the study at the Children's Hospital of Philadelphia and the University of Pennsylvania, said such a rapid decline in glycaemic control had been unproven until now, although the findings were not unexpected.
She pointed out that "the decline in reserve over time in childhood type 2 diabetes mellitus (T2DM) would be more severe for those presenting with diabetic ketoacidosis (DKA)".
Dr Katz added: "The more rapid deterioration of glucose control in children with type 2 diabetes is unsettling because of the myriad potential diabetic complications that may develop earlier than is seen in adults."
