Abstract:While Type 2 diabetes mellitus (T2DM) continues to be a disease of the elderly and the middle aged, currently there has been an upsurge in the incidence of T2DM in the adolescents and the young. Family history, maternal gestational diabetes, low birth weight have contributory role to play in the pathophysiology of T2DM. The pathophysiology underlying the development of alterations in glucose metabolism ranging from abnormal fasting glucose (AFG) to impaired glucose intolerance (IGT) is multifactorial. The early onset of diabetes in childhood or adolescence heralds a long disease interval with resultant escalation of the probability of development of co-morbidities and the entire range of macro-and microvascular complications.
