什么是胃镜检查
胃镜检查是借助一条包裹着导光纤维，直径约1公分的纤细、柔软的塑胶管，前端装有内视镜，从患者的口中伸入胃中， 以检查受检者食道、胃、十二指肠。
胃镜检查能直接观察到被检查部位的真实情况，更可通过对可疑病变部位进行病理活检及细胞学检查，以进一步明确诊断，是上消化道病变的首选检查方法。

胃镜检查痛苦吗
传统胃镜检查
普通胃镜检查，医生多以右手持镜前端，将胃镜慢慢放入口腔至舌根部，这时会有明显的恶心感，而出现吞咽动作。随着吞咽的动作，食管上口随之呈开放状、医生会在开放的瞬间顺着开口将胃镜插进食道。
传统胃肠镜检查，时间长、痛苦多、往往恶心、呕吐、腹痛给胃肠镜检查带来困难，或者病人一听到胃肠检查就恐惧或拒绝检查，“做胃镜”这三个字给人的感觉就是痛苦与恶心，据有关资料显示在已接受胃肠镜检查和治疗的病人中，约半数人不愿意再接受检查，三分之一以上的人有恐惧心理。而且检查后短期内还会有咽喉部不适或疼痛，或出现声音嘶哑的现象。
无痛电子胃镜检查
目前大部分医院是采用一种麻醉的方法来进行“无痛”检查，但这并不是真正的无痛胃镜，有一定的副作用，如呼吸抑制甚至暂停，心率、血压下降，心排量降低。也还会出现一定程度的恶心。
真正的无痛胃镜是利用最先进的无痛胃肠检查仪来检查的，它是利用一种镜像扫描的科学技术，借助对人体无伤害的超声助显剂在人体外对人体内部进行全方位扫描检测，以取得胃肠检查结果，不需插管和麻醉，无副作用，非常轻松，快速，并且无任何痛苦，结果准确。

胃镜检查有多痛苦
胃镜检查并不疼，在管子伸进去的时候会感觉很恶心想吐，从管子伸入喉头的时候，眼泪就会条件反射的往下掉。检查过程中你会感觉度秒如年，呼吸不顺畅，好像马上要窒息了一样，做完后还会干呕半天。
整个过程大约要5-10分钟，这个是因人而异的，跟医生配合的好，检查的时间就会短，配合不好，痛苦的时间也会拉长。
