‘Ihavenoappetite’鑒別診斷Differentialdiagnosis:1.厭食（對食物不感興趣）或只有早飽感（覺得食物誘人但患者在吃了幾口以后就覺得飽脹）2.原發(fā)性厭食（惡病質(zhì)綜合征）或繼發(fā)性厭食3.軀體的（例如，引起嘔吐）或精神心理的（例如,感到抑郁）

GastricStasis

胃動力藥，例如：滅吐靈，嗎叮林不要同時處方胃動力藥和抗毒蕈堿藥，因為后者競爭性阻斷胃動力藥的膽堿能末端的共同通路。Prokineticdrug,e.g.metoclopramide,domperidoneDonotprescribeaprokineticandananti-muscarinicdrugconcurrentlybecausethelattercompetitivelyblocksthecholinergicfinalcommonpathwayoftheprokinetic15非藥物治療
