Its diagnosis is based on a fasting blood-glucose level of ≥1.26g/L or, in some countries, a blood glycated haemoglobin (HbA1c) level of >6.5%. Of the several forms of diabetes, type-2 diabetes (T2D) is the most common and is found in patients with other risk factors. In contrast, type-1 diabetes (T1D) is linked to the autoimmune destruction of β-pancreatic cells, leading to insulinopaenia. Insulin deficiency results in diabetic ketoacidosis within a few hours. ‘Pancreatic’ diabetes develops from certain pancreatic diseases and may culminate in insulinopaenia. Treatments for T2D include non-insulin based therapies and insulin when other therapies are no longer able to control glycaemic levels. For T1D, treatment depends on long (slow)-acting insulin and ultra-rapid analogues of insulin administered according to a ‘basal-bolus’ scheme or by continuous subcutaneous delivery of insulin using a pump. For patients presenting with previously undiagnosed dysglycaemia, investigations should determine whether the condition corresponds to pre-e...
