Obesity can cause various deleterious effects on Respiratory function, such as alterations in respiratory mechanics, decrease in respiratory muscle strength and endurance, decrease in pulmonary gas exchange, lower control of breathing, limitations in pulmonary function tests and exercise capacity and impair health and quality of life. Obesity may affect several body systems and therefore, lead to higher morbity and mortality rates in the population. Of all those affected, the respiratory system derives special attention because obesity promotes important change in its mechanics, intolerance to exercise, gas exchanges, Control of respiration pattern and the strength an endurance of respiratory muscle. It is important risk factor for reduced airflow or lung function. Lower Peak Expiratory Flow rate (PEFR) value in obese subject is due to increase in the total peripheral resistance and airway resistance. 1.
