Prediabetes in sub-saharan Africa: Pathophysiology, predictors, and prevalence
Prediabetes – comprising impaired fasting glycaemia (IFG) and/or impaired glucose tolerance (IGT) – is a transitory median interphase between normal blood glucose levels and diagnostic levels of diabetes. The raised blood glucose levels surreptitiously damage the body's organ systems and are of...

Prediabetes – comprising impaired fasting glycaemia (IFG) and/or impaired glucose tolerance (IGT) – is a transitory median interphase between normal blood glucose levels and diagnostic levels of diabetes. The raised blood glucose levels surreptitiously damage the body's organ systems and are often an augury of type 2 diabetes mellitus (T2DM), the two having been found to share similar pathogenesis. Current concepts in the pathogenesis of prediabetes support a pentad of mechanisms responsible for its development. Majority of the countries in Sub-Saharan Africa belong to the low and middle income category, whose population accounts for more than 70% of the 352 million adults (20–79 years) worldwide with IGT (one component of prediabetes), as at 2017. The presence of prediabetes increases health care related expenditure in individuals and takes a toll on the workforce. Nigeria (West Africa) is currently among the top ten countries with the highest number of individuals with IGT as at 2017, and Ethiopia (East Africa) has been projected to join Nigeria in this category by 2045.
