This disease commonly manifested by wheezing, coughing and dyspnea causing a pulmonary obstruction, diagnosed by spirometry with proof-pharmacodynamics. Some patients with asthma not attend the typical clinical picture, being oligoassintomáticos or asymptomatic, which makes diagnosis of the disease. But are diagnosed by spirometry testing with pharmaco-dynamics, demonstrating a dissociation clinical spirometric x, then being considered carriers of the "silent asthma".Objectives: Join the "silent asthma" in normal weight, overweight and obese.Methods: We evaluated 156 patients in outpatient endocrinology, 63 patients from the University Hospital Professor Edgar Santos and 93 patients from a private clinic. All patients were asymptomatic respiratory historico without asthma, allergic rhinitis, diabetes mellitus, hypothyroidism or decompensated thoracic deformity. To confirm the diagnosis of "silent asthma" were performed in all patients, clinical evaluation and pharmacodynamic test with spirometry. The weight status was through the Body Mass Index, recommended by the World Health Organization (WHO).Results: The weight status showed 32 patients with normal weight, 39 were overweight and 85 obese patients. The incidence of "silent asthma" in a patient with normal weight was 1% (01 patients), overweight 7.89% (3 patients), grade I obese 26.32% (10 patients), obese grade II 15.79% (6 patients) and grade III obesity 47.37% (18 patients). Conclusion: The results of this study showed that there is a positive association between body mass index with high occurrence "silent asthma". ER -
