Abstract

Asthma and obesity have a considerable impact on public health and their prevalence has increased in recent years. Numerous studies have linked both disorders. Most prospective studies show that obesity is a risk factor for asthma and have found a positive correlation between baseline body mass index (BMI) and the subsequent development of asthma, although these results are not conclusive when studying the association between airway hyperresponsiveness with BMI. Furthermore, several studies suggest that whereas weight gain increases the risk of asthma, weight loss improves the course of the illness. Different factors could explain this association. Obesity is capable of reducing pulmonary compliance, lung volumes and the diameter of peripheral respiratory airways as well as affecting the volume of blood in the lungs and the ventilation-perfusion relationship. Furthermore, the increase in the normal functioning of adipose tissue in obese subjects leads to a systemic proinflammatory state, which produces a rise in the serum concentrations of several cytokines, the soluble fractions of their receptors and chemokines. Many of these mediators are synthesized and secreted by cells from adipose tissue and receive the generic name of a...Continue Reading
