胃的一个功能是储存食物，因此，胃的容量可能会限制食物的摄入量。胃容量大的人往往会吃更多的测试餐。我们比较了三组女性的胃容量：正常(n=10)、肥胖(n=11)和暴食症(n=10)。在隔夜禁食后，通过向胃球囊中注入100ml/min的水来估计胃容量，并停顿以测量胃内压。一种估计是基于受试者能耐受的最大容量，如腹部不适的最大评级所示。另一种估计是基于产生给定的胃内压升高所需的体积，5CIN H2O。第三个相关的衡量标准是基于满足度的最高评级。根据这些估计，暴食症患者的胃容量最大，肥胖受试者居中。然后，我们根据肥胖受试者是否报告暴饮暴食(n=6)或不暴饮暴食(n=5)将他们分开。暴饮组的胃容量与暴食组相似，而非暴食组的胃容与正常组相似。因此，胃容量似乎更多地与暴饮暴食行为有关，而不是与体重有关。(C)2001 Elsevier Science Inc.保留所有权利。
One function of the stomach is as a reservoir for food; hence, the stomach's capacity may limit the amount of food ingested. A stomach with a large capacity has been associated with bigger test meals. We compared the stomach capacity of three groups of women: normal (n = 10), obese (n = 11), and bulimic (n = 10). Following an overnight fast, gastric capacity was estimated by filling a gastric balloon with water at 100 ml/min, with pauses for measuring intragastric pressure. One estimate was based on the maximum volume the subject could tolerate as indicated by a maximal rating of abdominal discomfort. Another estimate was based on the volume required to produce a given rise of intragastric pressure, 5 cin H2O. A third related measure was based on a maximal rating of fullness. Based on these estimates, the gastric capacity of the bulimics was the largest, with the obese subjects intermediate. We then separated the obese subjects according to whether they reported binge eating (n = 6) or not (it = 5). The gastric capacity of the binge-eating subset was similar to the bulimics, and the nonbinge-eating subset was similar to the normals. Thus, gastric capacity appears more related to binge eating behavior than to body weight. (C) 2001 Elsevier Science Inc. All rights reserved.
