频繁便血到底是怎么回事?【石家庄靠谱的肛肠医院】

很多人发现自己大便带血，第一反应就是“上火了”，喝点水、吃点清淡的就不管了。但偶尔便血是上火，频繁便血绝对是身体预警，绝对不能硬扛、忽视。

反复便血并不是单一原因导致，有良性小问题，也有需要警惕的肠道问题，学会看便血状态，就能初步判断病因！

最常见原因：内痔（90%人的便血来源）

排便手纸带血、滴血、喷射状出血，血和大便不混合，单纯附在大便表面，肛门没有疼痛感，多半是内痔导致。久坐、便秘、久蹲厕所、吃辣熬夜，都会让内痔反复充血破损，造成频繁便血。

肛裂便血：疼到不敢排便

大便干结、过硬，排便时撑破肛门皮肤，会出现少量鲜血，伴随明显刺痛、撕裂痛感，便后疼痛会持续一段时间。长期便秘人群最容易反复发作。

肠道炎症：黏液便血

如果大便带血，同时混有白色黏液、脓液，频繁腹痛、拉肚子、排便不干净，大概率是慢性肠炎、直肠炎症刺激黏膜出血，属于肠道受损信号。

重视起来，积极行动

便血从不无缘无故，偶尔一次可观察，连续3次以上频繁便血，不管痛不痛、出血量多不多，都不要当成上火！及时调整作息饮食，必要时做肛肠筛查，避免小问题拖成慢性反复性疾病。
