In 2001, the ADA published a consensus statement relating to PPG and subsequently, in 2014, the International Diabetes Federation (IDF) released specific strategies for the management of PPG excursions in type 1 and type 2 diabetes advocating the use of dietary strategies (such as low glycemic index foods) and use of anti-diabetic medications (such as GLP-1 agonists) which target postprandial glycaemia (2, 6). Here, GCG is linked to type 2 diabetes mellitus.
