Common causes of abnormal leucorrhea: leucorrhea is a mixture of vaginal mucosal exudate, cervical canal, that is, endometrial gland secretion, etc. Its formation is related to the role of estrogen. Normal leucorrhea is white paste or egg white, which is sticky and tasteless, and has no adverse effect on women's health, so it is called physiological leucorrhea. However, if there is inflammation in the reproductive tract, especially vaginitis, cervicitis, or cancer occurs, the amount of leucorrhea will increase obviously and the characteristics will change, which is called pathological change. Clinically, the common pathological leucorrhea is: 1 colorless transparent viscous leucorrhea: egg white-like, similar to mucus secreted by cervical glands during ovulation, but the amount is obviously increased. Generally, the possibility of chronic endocarditis, ovarian dysfunction, vaginal adenopathy or cervical well-differentiated adenocarcinoma should be considered. 2 white or grayish yellow foamy leucorrhea: It is a feature of trichomonal vaginitis, which may be accompanied by vulvar itching. 3 curd-like (bean curd residue-like) leucorrhea: it is a characteristic of fungal vaginitis, often accompanied by severe vulvar itching or burning pain, or sexual pain. 4 gray homogeneous fishy leucorrhea: common in bacterial vaginitis. Purulent leucorrhea: yellow or yellowish green, sticky and smelly. Acute vaginitis, cervicitis and cervicitis caused by trichomonas or gonococcus can all be caused. Purulent leucorrhea can also be caused by pus in uterine cavity, uterine cancer, vaginal cancer or foreign body in vagina. 6 bloody leucorrhea: mixed leucorrhea, cervical cancer, endometrial cancer, cervical polyp or submucosal myoma should be considered. Placement of intrauterine devices can also cause bloody leucorrhea. 7 watery leucorrhea: continuous outflow of watery leucorrhea from rice washing. Those with strange smell are generally late cervical cancer, vaginal cancer or submucosal myoma with infection. Paroxysmal discharge of yellow or red watery leucorrhea should pay attention to the possibility of tubal cancer.
