| - | Surgery is often used for cases of extreme obesity or if all other conservative treatment methods are not successful (Wirth et al., 2014). It can also be recommended as a primary treatment before trying conservative methods if it is believed that they will have no effect. Surgery is often used for three different grades of obesity that are characterized by BMI (Wirth et al., 2014). Grade I is for individuals with a BMI between 30 and 35, with type 2 diabetes. Grade II obesity categorizes individuals with a BMI between 35 and 40 with significant co-morbidities, while grade III obesity means the individual has a BMI over 40. Different types of surgery can also be used such as sleeve gastrectomy (a), gastric banding (b), and gastric bypass (c). Overall, surgery is more effective in reducing body fat, decreasing obesity related disease, and decreasing mortality risk due to the large impact it can have compared to other treatments (Lawlor & Chaturvedi, 2006). To put this into perspective, one study found that in a one to two year time span, individuals were able to lose 20-40kg through bariatric surgery, 4-6kg through dietary therapy, and only 2-3 by exercise therapy (Lawlor & Chaturvedi, 2006). However, these results would vary depending on the individual, their dedication, and maintenance of their health goals. | + | Surgery is often used for cases of extreme obesity or if all other conservative treatment methods are not successful (Wirth et al., 2014).
