Type 1 Diabetes (T1DM) is a disease characterised by immune mediated destruction of the insulin-producing pancreatic beta cells. Overtime, obvious insulin deficiency develops which requires insulin therapy. T1DM accounts for about 5% to 10% of diabetes cases in Europe and United States. Currently, worldwide incidence is estimated to be around 15 per 100,000 people per year. Despite the advancement that has occurred in the field diabetes therapy, patient with T1DM still suffer from managing their disease as well as continuing to face diabetes related complications. The American Diabetes Association (ADA) recommend a goal of glycated haemoglobin (HbA1c) of \< 7%. However, only 21% of adults in the United States has achieved this recommended goal. Once again, a multinational, multicentre study shows that only 24.3% of participants achieved the glycaemic target of HbA1c less than 7.0 %. Unfortunately, intensifying the insulin therapy in order to reach the targeted HbA1c can result in serious adverse effects of hypoglycaemia and weight gain which is in its turn is known risk factor for cardiovascular disease.
