Specific Considerations With Pulmonary Disease - Obesity

Obesity is defined as the abnormal accumulation of excessive fat, leading to risks for a patient’s health. The ratio of weight to the square of height, known as BMI, is a widely used anthropometric measurement, with 30 kg/m 2 being the typical threshold for the definition of obesity.
