排便频繁

    2026 年 8 月 19 日

    定义

    排便频繁意味着排便次数多于平时。没有一个固定次数可以用来判断是否有排便频繁。您可能会认为每天排便多次是不正常的,尤其是如果这与您平时的排便次数不同时。无其他症状下排便频繁可能起因于您的生活方式,比如吃了更多纤维。水样便和腹部痉挛等症状可能提示某种问题。

    原因

    如果您排成形便的次数增多,很可能是意味您的生活方式有所改变。例如,您的全谷物摄入量可能有所增加,这会增加您从饮食中获取的纤维量。

    排便频率增加也可能由一种会自愈的温和疾病引起。如果没有其他症状,您的健康状况可能不错。

    可能导致排便频繁和其他症状的疾病和其他医疗状况包括:

    以下显示该症状的相关常见原因。请与医生或其他医务人员配合,以获得准确诊断。

    何时就医

    • 大便外观或大小发生变化,例如细长的带状大便或松散的水样便。
    • 胃疼。
    • 粪便带血或黏液。
