Amiodarone-induced Hyperthyroidism during Massive Weight Loss Following Gastric Bypass

摘要: Gastric bypass is increasingly used in morbidly obese patients to achieve significant reduction of body weight and fat mass concurrent improvement co-morbidities. We report the case a 53-year-old male patient (141 kg, BMI 50 kg/m2), successfully treated by amiodarone for supraventricular arrythmia, who underwent Roux-en-Y gastric (RYGBP). 6 months after surgery, he had lost 45% his preoperative (44.8% loss was lean mass) developed amiodarone-induced subclinical hyperthyroidism. hypothesize following sequence events: RYGBP, therefore loss, decrease distribution volume inducing iodine overload hyperthyroidism, reinforcing particularly mass. This emphasizes importance careful monitoring composition changes RYGBP. In this situation, checking thyroid status recommended, especially when there history disease or potentially toxic medication.
