Abstract Background and objective: To observe the prevalence of atelectasis in patients undergoing bariatric surgery and the influence of the body mass index (BMI), gender and age on the prevalence of atelectasis. Method: Retrospective study of 407 patients and reports on chest X-rays carried out before and after bariatric surgery over a period of 14 months. Only patients who underwent bariatric surgery by laparotomy were included. Results: There was an overall prevalence of 37.84% of atelectasis, with the highest prevalence in the lung bases and with greater prevalence in women (RR = 1.48). There was a ratio of 30% for the influence of age for individuals under the age of 36, and of 45% for those older than 36 (RR = 0.68). There was no significant influence of BMI on the prevalence of atelectasis. Conclusion: The prevalence of atelectasis in bariatric surgery is 37% and the main risk factors are being female and aged over 36 years.
