"Effect Of Surgically Induced Weight Reduction In Morbid Obesity On Pulmonary Function Tests

"           ياسر عبد الرؤوف الشاذلي          

Obesity is a condition in which a person has excess body weight relative to other people of the same gender and height. Morbid Obesity is a serious illness that can lead to many medical complications including cardio-vascular, metabolic, musculoskeletal and many respiratory complications.

Obesity may have a significant effect on normal lung physiology and subsequently reduction in pulmonary function tests.

Obesity must be recognized as a chronic condition requiring long-term therapy using different methods of therapy including diet control, increase physical activity, medications and surgical intervention in case of morbid obesity.

The aim of the present study  is assessment of the effect of weight reduction surgery ,as a method of management of morbid obesity, on pulmonary function tests.

The present study  thirty morbid obese patients had baseline BMI ≥ 40 kg/m2   who were admitted to hospital for gastroplasty. Pulmonary function test performed before gastroplasty and one month, three months after gastroplasty. Patients were stratified according to their pulmonary function test results prior to surgery into groupI (9 morbid obese patients- with normal pulmonary function tests) and group II ( 21 morbid obese patients- with abnormal pulmonary function tests). In both groups there was significant improvement in pulmonary function test results, especially in FEF25-75, after three months of gastroplasty.

From this study, it is concluded that morbid obesity may lead to pulmonary function impairment, specifically small airway disease affection reflected by decrease in FEF25-75 which improve after weight reduction."
