However, other sources suggest that bariatric surgery can be an effective tool for teenagers with severe obesity to lose weight and reverse the progression of weight-related conditions. For example, a study found that 60% of adolescents maintained a weight reduction of at least 20% five years after surgery. Another source reports that on average, adolescents who undergo weight loss surgery will lose 60% of their excess weight after one year. It is important to note that bariatric surgery should be considered in adolescents with moderate to severe obesity who have previously participated in lifestyle interventions.
