Obesity is a rising epidemic, and is one of the most common, costly and preventable health problems the world is experiencing today (Center for Disease Control and Prevention, [CDC], 2017).

 From this, it is important to establish an effective treatment plan that can be implemented across the nation for maximum patient benefit.

 Lifestyle changes such as diet and exercise are important to any health care plan and are equally necessary to reduce health risks. However, in certain patients, lifestyle changes are not enough due to the maladaptive biologic process in their brain. Thus, additional treatment options need to be available to these patients.

 Both medical therapies, pharmacological and surgical, were found to be beneficial in augmenting lifestyle changes in multiple studies. Therefore, it was concluded that pharmacologic and surgical therapies are valid options in resistant obesity in addition to lifestyle changes such as diet and exercise.

 This study was a systematic literature review which evaluated studies from CINAHL, Clinical Key, Cochrane Library, and PubMed to formulate a conclusion. Research focused on two pharmacotherapy options, phentermine and orlistat, in addition to two surgical options, gastric bypass and sleeve gastrectomy, for added weight loss treatment when compared to lifestyle alone.
