Surgical treatment for obesity is applicable under certain conditions. This requires the obesity to reach a specific level, defined by indicators such as a BMI of over 35, and in the absence of severe diabetes or complications associated with diabetes. Considering surgical interventions for weight loss, these primarily involve bariatric surgeries like gastric bypass or gastroenterostomy which reduce food intake and absorption, thereby decreasing calorie absorption to achieve weight loss. While the effects of surgical weight loss are generally quite good, it can lead to some long-term postoperative complications, so careful consideration is required.
