Teen’s Bariatric Surgery at 13 Sparks shift in Brazilian Medical Guidelines
RIO DE JANEIRO – A recent decision by Brazil’s Federal Council of Medicine (CFM) to ease restrictions on bariatric surgery for adolescents was informed, in part, by the experience of Michel, a young man who underwent the procedure at age 13. Michel’s story highlights the evolving understanding of obesity as a genetic condition and the potential benefits of early intervention.
Before surgery, Michel and his family rigorously pursued conventional weight loss methods. “My parents did everything. Thay didn’t bring sweets home, we ate low-fat meat, brown rice, beans, but it was a genetic issue and I couldn’t do it,” he recalled. Despite these efforts, his weight continued to impact his quality of life, leading to both physical pain and social isolation.
The decision to pursue bariatric surgery wasn’t taken lightly. Michel spent months undergoing extensive psychological, nutritional, and medical evaluations. As a minor,his parents were required to sign a liability waiver.
Now 18, Michel reflects on the transformative impact of the surgery. “After the surgery, my social life changed entirely. I started to have friends at school, which made me question: I was the same person, I had just changed my body,” he said. Standing at 1.75 meters and weighing 67 kilograms, he is now free from the knee and leg pain that previously plagued him. “I say that the surgery gave me the freedom to be who I am,” explains the young man, who currently works as a singer, dancer, and actor.
Historically,bariatric surgery for adolescents in Brazil was limited to experimental cases within approved research protocols or those authorized by the courts. However, in May of this year, CFM Resolution 2,429/2025 broadened access to the procedure for teenagers facing similar challenges to Michel. The updated guidelines aim to provide more young peopel with the opportunity to address severe obesity and improve their overall health and well-being.
