The nutrition of 200 patients after Roux-en-Y gastric bypass for morbid obesity was followed for 6.7 years. During the first 2 years their food intake was severely restricted, resulting in an excess weight loss of 69 +/- 14%. At an average of 3 years after surgery they began to regain weight significantly (p less than 0.04) due to nutritional adaptation. In the following years caloric consumption stabilized at an excess weight loss of 48-56%. However, they had continuing meat intolerance with 51.0, 60.3, 59.5 and 55.1% of them avoiding meat during 0-12 months, 13-24 months, 25-72 months and 73-96 months after surgery, respectively. We conclude that after Roux-en-Y gastric bypass there is nutritional adaptation lasting as long as 2 years, when a characteristic nutritional behavior is adopted which persists for years.
对200例因病态肥胖接受Roux-en-Y胃旁路手术的患者的营养状况进行了6.7年的跟踪研究。在术后的头两年，他们的食物摄入量受到严格限制，超重体重减轻了69±14%。术后平均3年时，由于营养适应，他们开始显著体重增加（p<0.04）。在接下来的几年里，热量消耗稳定在超重体重减轻48-56%的水平。然而，他们持续存在肉类不耐受情况，在术后0-12个月、13-24个月、25-72个月和73-96个月时，分别有51.0%、60.3%、59.5%和55.1%的患者避免食用肉类。我们得出结论，Roux-en-Y胃旁路手术后存在长达2年的营养适应期，在此期间会形成一种持续数年的特征性营养行为。
