Summary

Asthma is more frequent in obese women, but the mechanisms underlying the causes of this increased frequency are unknown and are different from usual asthma pathophysiology (associated with allergy). Obesity is known to influence ventilation; our hypothesis is that the normal variability of ventilation is decreased in obese patients, and that this decrease is responsible for an increased reactivity of their airway to non specific stimuli. In this observational study, breathing variability will be studied using polygraphy (an investigation that is made in these women to detect nocturnal apneas), and airway reactivity is studied between pulmonary function tests that are made before bariatric surgery.
