The prevalence of obesity has increased so rapidly over the last few decades that it is now considered a global epidemic. Obesity, defined as a body mass index (BMI) of 30 or more, is associated with several comorbid conditions that decrease life expectancy and increase health care costs. Diet therapies have been reported to be ineffective in the long-term treatment of obesity, and guidelines for the surgical therapy of morbid obesity (BMI ≥ 40 or BMI ≥ 35 in the presence of substantial comorbidities) have since been established. Considering the number of bariatric surgical procedures has dramatically increased since these guidelines were established, we review the types of bariatric surgical procedures and their impact on diabetes, sleep apnea, dyslipidemia and hypertension - 4 major obesity-related comorbidities.
