用泻药自我诱导的净化在暴食症患者中很常见，他们认为净化会减少肠道对摄入热量的吸收。清除在减少热量吸收方面的功效从未被研究过，可能是因为标准的热量平衡程序既昂贵又耗时。用最近设计的方法，测量一天中的卡路里吸收，以确定酚酞或盐水冲洗减少卡路里吸收的程度。在2名经常使用泻药控制体重的贪食症患者和5名正常年轻女性中，即使是产生4-6升腹泻的极端泻药也仅导致卡路里吸收减少约0.05。12%的卡路里摄入量。服用泻药来控制体重的理论基础是不可靠的。
Self-induced purging with laxatives is common among bulimic persons, who assume that purging reduces intestinal absorption of ingested calories. The efficacy of purging in reducing calorie absorption has never been studied, probably because the standard calorie balance procedure is expensive and time consuming. With a recently devised method, calorie absorption during a single day was measured to determine to what extent phenolphthalein or saline purge reduced calorie absorption. In 2 bulimic patients who regularly used laxatives for weight control and 5 normal young women, even extreme purging producing 4-6 l of diarrhea caused calorie absorption to decrease by only .apprx. 12% of calorie intake. The theoretical basis on which laxatives are taken for weight control is unsound.
