Abstract:
Obesity is a global health hazard. As standards of living are continuing to rise, weight gain and obesity are posing a growing threat to health in countries all over the world. These obese individuals are at increased risk of morbidity and mortality because of its relationship with various metabolic disorders. The Efficiency and functional status of Lungs can be assessed by using these simple tests and effective for diagnosis of various lung diseases. To find out the association, including gender differences, between body mass index and lung functions identified obese and nonobese adults. By spirometric protocols. The Respiratory function was recruited in hundred obese adults and 100 non obese adults aged between 25-45 years, including both sexes. Among obese subjects significant correlation is found between BMI and pulmonary function value decreased response of FVC, FEV1 and FEV1%. Significant association was found between BMI and lung function in obese female and obese male. Finally signifying that decreases efficiency of lungs occurs in Obesity. The present work conclude that early detection of functional impairment of respiratory changes and its appropriate management is the only means by which the morbidity and mortality can be reduced.
