A recent systematic review also found strong evidence for Type 1 diabetes mellitus as a consequence of childhood obesity; moreover, some of the consequences of obesity such as Type 2 diabetes mellitus, hypertension and hyperlipidemia were previously seen only in adult but are now frequently observed in obese child in some populations.
Type 2 diabetes mellitus occurs predominantly on young people (diagnosis at 30 years of age or younger) and is generally thought to be he immune system is activated and destroy the insulin-producing pancreatic beta cell, leading to insulin deficiency. Type 2 diabetes mellitus is a progressive metabolic disease that is characterized by our skeletal muscles become resistant to insulin’s effects or functional failure of pancreatic beta cells which leads not enough insulin produced. For Type 2 diabetes mellitus, the onset at younger age not only prolongs the duration of the disease but also is associated with a more advanced rate of progression to beta cells failure and is likely to lead earlier presentation of adult-life complications such as cardiovascular disease, kidney failure, visual impairment and limb amputations. And these can be preventable by modifying lifestyle in childhood.
