The maximal tolerable distension of the stomach was measured with a balloon system in 16 extremely obese and 11 normal-weight subjects. The mean maximal tolerated volume was significantly greater in the obese group (1763 +/- 70 vs. 1000 +/- 67 ml). The volume at which a satiety-simulating sensation appeared was likewise greater in the obese group (850 +/- 74 vs. 541 +/- 44 ml). The intragastric pressure originating from the stomach wall as such presumably was similar in both groups. The greater capacity for gastric distension in extremely obese persons may be an etiologic factor in the development of obesity or an adaptation to the eating pattern.
采用气囊系统对16名极度肥胖者和11名正常体重者的胃最大可耐受扩张程度进行了测量。肥胖组的平均最大耐受容量显著更大（1763±70 vs. 1000±67 ml）。肥胖组出现饱腹感模拟感觉时的容量同样更大（850±74 vs. 541±44 ml）。两组中胃壁产生的胃内压推测相似。极度肥胖者更大的胃扩张能力可能是肥胖发生的一个病因因素，或者是对饮食模式的一种适应。
