| Studies that assessed orlistat therapy for at least 2 years and up to 5 years showed that weight loss attained by year 1 was better maintained over the subsequent 3 years in patients who received ongoing drug therapy. Specifically, Davidson et al. showed that patients who had ongoing treatment of orlistat for 2 years were associated with less regain of weight loss (32%) compared with diet only therapy (63%) <sup>[45]</sup>. | Studies that assessed orlistat therapy for at least 2 years and up to 5 years showed that weight loss attained by year 1 was better maintained over the subsequent 3 years in patients who received ongoing drug therapy.

| Bariatric surgery is a treatment method that is considered for adult patients who have a BMI over 35kg/m^2 with severe comorbid diseases such as life-threatening cardiopulmonary problems, severe sleep apnea, or severe diabetes mellitus, or for those in the severely obese category with a BMI greater than 40 kg/m2. For teenagers, the Canadian Clinical Practice Guidelines on the Management and Prevention of Obesity in Adults and Children recommends that bariatric surgery be limited to an appropriately trained and experienced surgical team. After 6 months of using lifestyle modifications, healthcare practitioners assess the health of the patient and evaluate whether a satisfactory progress of weight loss or goal of 10% of body weight has been reached. In the case that satisfactory progress or goal has not been achieved, physicians will consider the eligibility of patients to undergo bariatric surgery. This is only considered if other nonsurgical weight loss attempts have failed. The goal of bariatric surgery is to relieve a patient suffering from obesity from his or her morbid body weight, improve their comorbidity and improve their quality of life. There are different surgical procedures (Figure 13). It is important to note that this treatment option requires lifelong medical surveillance <sup>[26]</sup>. | Bariatric surgery is a treatment method that is considered for adult patients who have a BMI over 35kg/m^2 with severe comorbid diseases such as life-threatening cardiopulmonary problems, severe sleep apnea, or severe diabetes mellitus, or for those in the severely obese category with a BMI greater than 40 kg/m2.

| A study on obese Swedish patients investigated the conventional, nonsurgical management with surgery for morbid obesity in 2004 found that surgical management is more efficacious than medical management. Patients who received surgical treatment produced greater weight loss, improved lifestyle and dramatic improvement of comorbid disease. At 10 years of follow-up, the surgical cohort showed that they maintained a weight loss greater than 16.1% of their original body weight. In contrast, those who received the conventional, nonsurgical management had a weight gain of 1.6%. This 16.3% weight difference demonstrates the effectiveness and maintenance of surgical procedures <sup>[47]</sup>. | A study on obese Swedish patients investigated the conventional, nonsurgical management with surgery for morbid obesity in 2004 found that surgical management is more efficacious than medical management.

| As seen in figure 14, there are different approaches to treating obesity. First, it is important to set a weight loss goal to reduce body weight by approximately 10% from baseline during the first six months of treatment. Healthcare practitioners typically recommend their patients to first undergo lifestyle modifications: proper nutrition, physical fitness, and cognitive behaviour therapy. After six months of treatment, healthcare practitioners will assess the patient’s progress and determine whether satisfactory progress or weight loss goal has been reached. In the case that it has been reached, the patient would be closely monitored on a regular basis to make sure that their weight is maintained. In the event that satisfactory progress is not attained, physicians will assess the patient’s eligibility to either undergo pharmacotherapy or bariatric surgery. Physicians typically opt for bariatric treatment in the event that nonsurgical treatments have failed. It is important to note that best weight loss and maintenance results are achieved when pharmacotherapy or bariatric treatment is used in conjunction with lifestyle modifications. | As seen in figure 14, there are different approaches to treating obesity.
