Background: Childhood obesity is a serious medical condition where excess body fat negatively affects a child’s health. Although prevention is the primary step, there will be obese adolescents who benefit from bariatric surgery. There are four bariatric methods (all using laparoscopic technique): Adjustable Gastric Banding (AGB), Roux-en Y Gastric bypass (RYGB), sleeve gastrectomy and Bilio-Pancreatic Diversion (BPD). In Sweden we predominantly use RYGB as it improves eat...

The increase in childhood obesity prevalence led to the establishment of a monographic obesity clinic since 2009 in our Department. To date, over 1600 patients have been visited, focusing on early onset severity and generating a valuable dataset on the characteristics of these patients (“The Madrid cohort”). This has allowed the performance of genomic and genetic studies, which have led to the demonstration of a genetic background, underlying the development of the d...

Background: The survival of an organism relies on its ability to promptly, effectively and reproducibly communicate with brain networks that control food intake and energy homeostasis. To achieve this, circulating factors of hunger and satiety reflecting nutrient availability must cross the blood-brain barrier (BBB) to reach effectors neurons.Objective and hypotheses: Here I will discuss the key role played in this process by a peculiar type of glial cel...

Feeding behavior is exquisitely regulated by homeostatic and hedonic neural substrates that integrate energy demand as well as the reinforcing and rewarding aspects of food. Understanding the net contribution of homeostatic and reward-driven feeding has become critical due to the ubiquitous source of energy-dense foods and the consequent obesity epidemic. Hypothalamic, agouti-related protein-secreting neurons (AgRP neurons) represent primary orexigenic drives of homeostatic fe...
