Impact of obesity on lung function in healthy young individuals
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 6
Abstract
Background: Obesity is a chronic disease process characterized by excess fat accumulation in body leading to multiple organ specific consequences. It affects people of all ages, gender, race and class. It affects multiple organs including the respiratory system by various mechanisms. The lung function can be measured by spirometry which includes the FEV1, FVC and FEV1/FVC ratio. Aim: To study the impact of obesity on the lung function in young healthy individuals Material and Methods: Our study was conducted in Aarupadai Veedu Medical College and Hospital, Puducherry, for a period of one year from 2015 to 2016. A total of 50 individuals who were between 18 – 25 years of age, overweight or obese (BMI>25kg/m2), with no addictions/comorbid conditions. Individuals who had previous surgeries, TB/ infection affecting lung function or on drugs affecting the lung function were excluded from the study. They underwent Spirometry and data was collected. This was correlated with various parameters like gender, height, weight, BMI. HELIO spirometry was used and SPSS software was used for statistical purposes. Results: In our study we found a significant reduction in the FEV1, FVC values in individuals who were overweight to class III obesity. The mean of FEV1 and FVC reduced proportionally to increase in BMI. The ratio of FEV1/FVC was normal or slightly raised proving that a restrictive pattern of lung disease prevailed in overweight and obese patients. Conclusion: Obesity has a significant impact on the lung function of an individual. Obese people are at an increased risk of reduced lung function. The reduction in BMI by reducing weight can reduce the morbidity.
