How effective is obesity surgery?

Obesity surgery, also known as bariatric surgery, can be an effective tool in helping individuals achieve and maintain significant weight loss. Studies have shown that bariatric surgery can help patients reduce their body weight by up to 40-50% over a two year period. In addition to this weight loss, many health benefits accompany it such as mortality reduction for certain disease types (e.g cardiovascular disease)and resolution of type 2 diabetes in nearly 80% of patients after metabolic procedures like the gastric sleeve or gastric bypass.

Furthermore, additional studies suggest long-term success rates (five years or more) with regard to sustained weight loss following these surgeries remain higher than those achieved through lifestyle interventions alone by 10-30%. This is because the procedures not only remove fat but also modify hormones and physical sensations related to food intake – both of which plays an important role in successful maintenance of healthy bodyweight levels over time.
