This retrospective study aimed to evaluate how reduction mammaplasty influences the bodyweight of patients 5 years after the procedure. The literature shows controversy regarding the effect of breast reduction on the progression of bodyweight. Between 1 January 2006 and 31 July 2007, 249 reduction mammaplasties were performed in the Department of Plastic, Reconstructive, and Aesthetic Surgery at the University Hospital Innsbruck. The exclusion criteria ruled out patients with oncoplastic breast reduction plasties, unilateral reduction mammaplasty, no documented preoperative weight, and bariatric procedures. The study finally included 50 women with a mean age of 44 ± 12 years. Of these 50 women, 26 (52 %) gained weight, 18 (36 %) lost weight, and 6 (12 %) remained stable during a 5-year follow-up period after the procedure. The mean weight gain was 4.50 ± 3.5 kg, and the mean weight loss was 3.44 ± 2.20 kg. The results of the study suggest that reduction mammaplasty is not a stimulus for weight loss. Although a tendency to gain weight was discovered, the weight gain compared with that of the standard population did not reach statistical significance.

本回顾性研究旨在评估乳房缩小术后 5 年对患者体重的影响。文献显示，乳房缩小术对体重变化的影响存在争议。
2006 年 1 月 1 日至 2007 年 7 月 31 日，在因斯布鲁克大学医院整形、重建和美容外科进行了 249 例乳房缩小术。排除标准为肿瘤整形乳房缩小术、单侧乳房缩小术、术前体重无记录和减肥手术。本研究最终纳入 50 例平均年龄为 44±12 岁的女性。50 例患者中，26 例（52%）体重增加，18 例（36%）体重减轻，6 例（12%）在术后 5 年随访期间体重保持稳定。体重平均增加 4.50±3.5kg，体重平均减轻 3.44±2.20kg。研究结果表明，乳房缩小术不是体重减轻的刺激因素。尽管发现体重有增加的趋势，但与标准人群相比，体重增加并未达到统计学意义。
