Abstract
Introduction
Obesity has become so common in developed and developing nations that presently it replaces under-nutrition and infectious diseases as the most significant contributor to ill health. Globally it is assumed that there are more than 1 billion overweight adults and at least 300 million of them are obese. In the developing countries obesity is more prevalent in affluent class. A number of factors contribute towards becoming overweight, such as genetic, lifestyle habits, endocrine problems, genetic syndromes and medications.
Obesity has proved to be a major risk factor for a whole range of cardiorespiratory disorders. Obesity can profoundly alter pulmonary function and diminish exercise capacity by its adverse effects on respiratory mechanics, respiratory muscle function, lung volumes, work and energy cost of breathing and gas exchange. It is the most common precipitating factor for obstructive sleep apnea and obesity hypoventilation syndrome, both of which are associated with substantial morbidity and increased mortality.
