Obesity. which is assuming alarming proportions, has been attributed to genetic factors, hypothalamic dysfunction, and intestinal gut bacteria and an increase in the consumption of energy-dense food Obesity predisposes to the development of type 2 diabetes mellitus. hypertension, coronary heart disease. and certain forms of cancer Recent studies have shown that the intestinal bacteria in obese humans and mice differ from those in lean that could trigger a low-grade systemic inflammation Consumption of a calorie-dense diet that initiates and perpetuates obesity could be due to failure of homeostatic mechanisms that regulate appetite, food consumption. and energy balance Hypothalamic factors that regulate energy needs of the body, control appetite and satiety. and gut bacteria that participate in food digestion play a critical role in the onset of obesity Incretins. cholecystokinin, brain-derived neurotrophic factor, leptin, long-chain fatty acid coenzyme A. endocannabinoids and vagal neurotransmitter acetylcholine play a role in the regulation of energy intake, glucose homeostasis. insulin secretion. and pathobiology of obesity and type 2 diabetes mellitus Thus, there is a cross-talk among the gut. liver, pancreas, adipose tissue, and hypothalamus Based on these evidences, it is clear that management of obesity needs a multifactorial approach (C) 2010 Elsevier Inc All rights reserved
