Introduction: overweight is a public health problem and is associated with high prevalence of Systemic Arterial Hypertension and Diabetes Mellitus (DM), especially in morbidly obese. Objective: To determine the prevalence of hypertension and DM in obese candidates for bariatric surgery. Materials and Methods: retrospective study in a hospital, with 83 candidates for bariatric surgery, both sexes, aged between 18 and 59 years with body mass index (BMI) ≥ 35 kg/m² with hypertension and/or DM or BMI ≥ 40 kg/m² with or without comorbidities. Data were collected: name, age, sex, weight, height, BMI and existence of hypertension and/or DM (those ones were reported). For statistical analysis we used the software IBM SPSS 19, considering statistically significant, p<0.05. Results: female predominance (73.5%). The mean age and BMI ± standard deviation were, respectively: 41.5 ± 11.4 years and 52.39 ± 10.57 kg/m². Most of obese patients had BMI ≥ 50 kg / m² (53.0%). The prevalence of DM was 27.7%, hypertension, 71.1%. The prevalence of DM and associated hypertension was 27.7% because all diabetic patients were also hypertensive. Discussion: the female predominance can be explained by greater prevalence of obesity or because they tend to seek medical treatment. The hypertension is common in obese diabetic patients, which increases the risk of cardiovascular diseases. The prevalence of comorbidities may have been underestimated in this study because they were reported by the patients. Conclusion: the prevalence of hypertension found in candidates for bariatric surgery was 71.1%. All obese diabetic patients were also hypertensive, so the prevalence of DM and associated hypertension was 27.7%. There was no significant difference between both sexes in relation to BMI and comorbidities.
