Diabetes has been with us for a very long time, with the first records of Diabetes appearing as early as 1552 BC. Early treatments (as described by a French physician in the 1870s) linked the disease of diabetes to a person’s diet. Individual diet plans featured as an important part of diabetic treatment in these historical records. The discovery of insulin is generally accredited to Sir Frederick Grant Banting and his team at the University of Toronto in 1921. Banting and laboratory director MacLeod received the Nobel Prize in Physiology or Medicine in 1923, for their discovery.
This marked the very important emergence of insulin use in diabetic treatment. Early insulin therapy was largely based on bovine/porcine insulin collected from abattoirs. In 1955, the first oral hypoglycemic drugs were manufactured. In 1959, Type 1 and Type 2 Diabetes were recognised as separate medical conditions for the first time (marking the emergence of the diabetic treatment regimes followed today).
