Asthma and obesity: does weight loss improve asthma control? a systematic review.

Related Articles

AIM AND METHODS: Obesity is a major health problem, and obesity is associated with a high incidence of asthma and poor asthma control. The aim of the present paper is to systematically review the current knowledge of the effect on overall asthma control of weight reduction in overweight and obese adults with asthma.

RESULTS: Weight loss in obese individuals with doctor-diagnosed asthma is associated with a 48%-100% remission of asthma symptoms and use of asthma medication. Published studies, furthermore, reveal that weight loss in obese asthmatics improves asthma control, and that especially surgically induced weight loss results in significant improvements in asthma severity, use of asthma medication, dyspnoea, exercise tolerance, and acute exacerbations, including hospitalizations due to asthma. Furthermore, weight loss in obese asthmatics is associated with improvements in level of lung function and airway responsiveness to inhaled methacholine, whereas no significant improvements have been observed in exhaled nitric oxide or other markers of eosinophilic airway inflammation.

CONCLUSION: Overweight and obese adults with asthma experience a high symptomatic remission rate and significant improvements in asthma control, including objective measures of disease activity, after weight loss. Although these positive effects of weight loss on asthma-related health outcomes seem not to be accompanied by remission or improvements in markers of eosinophilic airway inflammation, it has potentially important implications for the future burden of asthma.

Allergy, living and learning: diagnosis and treatment of allergic respiratory diseases in Europe.

CONCLUSIONS: A notable proportion of individuals with respiratory allergy in Europe are underdiagnosed, undertreated, and dissatisfied with their treatment. Addressing these shortcomings may help to optimize respiratory allergy care and, ultimately, quality of life.

Less Than 50% Of Asthmatic Children Control Their Symptoms, Despite Available Treatments

The International Consensus (ICON) on Pediatric Asthma has been launched during the EAACI Congress 2012 in Geneva. The goal of this ICON is to highlight the key messages that are common to many of the existing guidelines, while critically reviewing and commenting on their differences, thus providing a concise reference. The Pediatric Asthma ICON provides advice for the best clinical practice in pediatric asthma management. Hundreds of millions of people in the world suffer from allergies, and it is estimated that 300 million* have asthma... (Source: Health News from Medical News Today)
