Abstract
- A epidemia da obesidade é considerada um importante problema de saúde pública na sociedade ocidental, pois ela se relaciona a comorbidades como síndrome metabólica, diabetes mellitus e hipertensão. A microbiota intestinal pode contribuir para o desenvolvimento da obesidade através do aumento da extração energética dos componentes da dieta, da lipogênese, da permeabilidade intestinal e da endotoxemia, mediada especialmente pelos lipopolissacarídeos. Estudos têm demonstrado diferenças na composição da microbiota intestinal entre indivíduos obesos e magros. Ao que parece, o aumento na proporção de Firmicutes em relação a Bacteroidetes parece estar presente na obesidade, podendo ser alterado à medida que ocorre perda de peso. Assim, o objetivo deste estudo foi revisar a literatura acerca dos mecanismos que relacionam a microbiota e a barreira intestinal ao desenvolvimento ou agravamento da obesidade. The epidemic of obesity is considered an important public health problem in the Western society and is related to comorbidities such as metabolic syndrome, diabetes mellitus, and hypertension. The intestinal microbiota may contribute to the development of obesity by increasing energy extraction from the dietary components, lipogenesis, intestinal permeability, and endotoxemia, especially mediated by lipopolysaccharides. Studies have demonstrated differences in composition of the intestinal microbiota between obese and lean individuals. Apparently, the increase in the proportion of Firmicutes in relation to Bacteroidetes seems to be present in obesity and can be changed during weight loss. The aim of this study was to review the mechanisms that relate microbiota and intestinal barrier to the development or worsening of obesity.
