如何区分胃热和胃寒
胃寒证是指因阴寒郁结于胃脘痛而导致的胃寒实证,故又称寒凝胃脘痛证。腹寒,暴饮暴食导致受寒,寒邪凝结于胃,引起气滞而发病。表现为胃脘冷痛,受寒加重,温度降低,口淡而不渴,或伴有口淡,舌淡,苔白滑,脉缓或弦。胃寒证应与胃气不足、寒性相鉴别。前者为实寒证,寒邪袭胃时急性发作,病情剧烈,病程短;后者为虚寒证,起病缓慢,病程长,不易痊愈,且多出现于脾胃虚寒证,伴有脾胃虚寒不能健的症状,如腹胀满,食后更甚,大便稀稀等。= = = = = = = = = = = = = = = = = = = = = = = = = = = = = =胃热证就是胃的实热证,也叫胃火证。根据其表现,可分为胃热郁结型和胃火炎型两种。前者病变局限于胃,亦称胃热或胃中潜火,表现为胃脘灼痛,吞酸嘈杂,或食后立即呕吐,或渴冷饮,或饥则小便赤涩,舌红苔黄,脉滑;后者的病变不仅在胃部,也在胃经沿线区域,引起牙龈肿痛、面颊肿胀、牙龈出血、咽扁桃体肿痛、口臭。胃热证应与胃阴虚证相鉴别。前者为胃热实证;后者为胃虚热证。
