[Medical interventions for the therapy of obesity]

Abstract

Obesity is a chronic disease characterized by increased body fat mass and adipose tissue dysfunction, the pathogenesis of which is based on a neurobiological regulatory disorder of energy homeostasis. The primary aim of medical obesity therapy is to reduce the pathologically increased body fat mass and thus prevent secondary diseases and improve comorbidities. In this sense, bariatric-metabolic surgery is currently the most effective obesity therapy. In addition, new agents, which are essentially based on GLP-1 receptor agonism, are making pharmacological therapy increasingly effective. It is important to note that both bariatric-metabolic surgery as well as the pharmacological obesity therapy have direct effects on the central nervous regulation of energy homeostasis and, in particular, hunger and appetite, and therefore represent pathogenetically causal therapies. In this overview, we aim to shed light on the aforementioned medical interventions for obesity therapy and place them in the context of a pathogenetic disease concept.
