白带异常女生白带上有血是怎么回事
白带是女性健康的一面镜子，正常的白带应是乳白色或无色透明，略带腥味或无味。其分泌量、质地受体内雌激素、孕激素水平高低的影响，随月经周期而有量多量少、质稀质稠的周期性变化。不过有女生表示，有时候白带会带有血，这是怎么回事呢?该如何预防白带异常呢?接下来将一一为大家介绍，供大家参考。
女生白带上有血是怎么回事?
1、排卵期出血
排卵期出血是因为雌激素水平短暂下降，使子宫内膜失去激素的支持而出现部分子宫内膜脱落引起有规律性的阴道出血，月经中期(排卵期)出现规律的阴道出血，量一般不多，持续半天或几天，可伴有轻搬腹痛或腰酸。
2、妇科炎症
常见引起白带有血丝的妇科炎症有宫颈糜烂，宫颈息肉、宫颈炎、老年性阴道炎等。另外，这些妇科炎症除了会表现出白带有血丝的症状，还会有白带增多，白带颜色改变，白带有异味等状况的出现。需要女性朋友加于区分，并引起注意。
3、其他因素
白带里有血丝与年龄、婚姻(性生活情况)或生育情况也有一定的关系，另外安放宫内节育器都可引起血性白带。
专家指出，白带里面有血丝有生理性的和疾病性的两种，一般来说女性在排卵期有的人会出现排卵期出血，即月经中期出血，是指两次正常量月经之间的少量出血，可伴有不同程度的小腹痛。如症状较轻无需治疗，出血量多或影响生育者可用药物治疗。
白带里面有血丝应该警惕是宫颈炎和宫颈息肉的发生，白带增多时宫颈炎和宫颈息肉最常见的，有时甚至是惟一的症状。白带增多、混浊，呈脓性或混带血，以及排尿症状如尿频、尿急等是宫颈炎和宫颈糜烂的典型症状。
如何预防白带异常?
1、尽量少用卫生护垫，如果分泌物多，易使裤底湿湿的，不妨经常更换内裤。
2、时下流行的丁字裤虽然性感，但不易吸汗，又容易造成磨擦破皮，易使细菌有入侵的机会，最好少穿。
3、如厕后，卫生纸应由前往后擦，而非由后往前，以免卫生纸先碰触肛门，可能将过多细菌带到阴道口。
4、外阴部和腋下一样，都是容易流汗的部位，最好每天洗澡，尤其运动出汗后更要立刻冲洗;选择吸汗的棉质内裤，避免闷热不透气的衣物如牛仔裤，保持阴部的干爽最重要。
5、除了霉菌，有些病原菌易存在男性身上，若女性发生感染，须注意性伴侣是否也有类似问题(如尿道炎)，应一并治疗，否则女性治好后，可能因性接触而交互感染，一再复发。
6、性行为也会增加感染的机会，行房前应清洗外阴部，行房后应以凯格尔运动(腹部用力、骨盆收缩)把精液排出，因为精液为碱性，会改变阴道酸碱值，想受孕的人也可采用此法，因精子跑得快，不受影响，或使用保险套，避免精液射入。
