Abstract
Background: Childhood and adolescent obesity is one of the most serious public health challenges of the 21st century. Obesity is defined as excess body fat or adipose tissue; that associated with comorbid conditions. Obesity affects the respiratory system by several mechanisms, including direct mechanical changes due to fat deposition on the chest wall, abdomen, and upper airway. The increase in body weight causes limitation of diaphragmatic mobility and reduced back movement, with impaired pulmonary gas exchange and breathing pattern control. Pulmonary diseases form a major cause of childhood morbidity and mortality and also a common reason for pediatric outpatient visits and hospital admissions. Pulmonary function assessment thus becomes a necessary investigation in the evaluation pathway of pediatric respiratory diseases. It measures the rate of changing lung volumes during forced breathing maneuvers. Patients and Methods: 30 obese children and adolescent compared with 30 healthy subjects which enrolled as controls. Every patient and control underwent full history, examination, anthropometric measures were taken and pulmonary function tests were done
