概述

功能性消化不良指无明显原因而反复出现的消化不良体征和症状。功能性消化不良也称为非溃疡性胃痛或非溃疡性消化不良。

功能性消化不良很常见,而且可能持续很长时间,但是体征和症状大多为间歇性。这些体征和症状与溃疡类似,例如上腹部疼痛或不适,通常还伴有腹胀、打嗝和恶心。

症状

功能性消化不良的体征和症状可能包括:

  • 饭后胃部疼痛或灼热、腹胀、过度嗳气或恶心
  • 进食时很快有饱腹感
  • 胃痛有时可能与进餐无关,或可随进餐而缓解

何时就诊

如果您对持续不消的体征或症状感到担忧,请与医生约诊。

如果您出现以下情况,请立即就医:

  • 血性呕吐物
  • 黑色、柏油样大便
  • 气短
  • 辐射到颚部、颈部或手臂的疼痛
  • 原因不明的体重减轻

病因

功能性消化不良的病因尚不清楚。医生认为这是一种功能障碍,这意味着常规检查可能不会显示任何异常,因此需要根据症状来诊断。

风险因素

可能增加功能性消化不良风险的因素包括:

  • 女性
  • 使用某些可能导致胃部问题的非处方止痛药,如阿司匹林和布洛芬(Advil、Motrin IB 等)
  • 抽烟
  • 焦虑或抑郁
  • 儿童期身体虐待或性虐待史
  • 幽门螺杆菌感染
