Normal leucorrhoea is an odourless, slightly acidic thick substance that has the effect of moistening the vagina, excreting waste and inhibiting the growth of pathogenic bacteria. The increase in leucorrhoea in healthy women is directly proportional to the increase in oestrogen levels in the body. So is abnormal leukorrhoea a disease? Generally speaking, this is the case. If the leukorrhea is abnormal, it is a sign of inflammation or some kind of disease.

　　Women can determine the type of disease by the colour, smell and nature of the leukorrhea:

　　1, purulent leukorrhea. The colour is yellow or yellow-green, sticky, with a fishy smell, mostly due to vaginal inflammation. Common in trichomonas vaginitis, chronic cervicitis, endometritis, uterine pus and vaginal foreign body.

　　2, tofu scum-like leucorrhoea. It is tofu dregs-like or curd-like small fragments, at the same time, the vulva itching unbearable, mostly for the typical phenomenon of mycosis fungoides vaginitis.

　　3、Bloody leucorrhoea. There is blood mixed in the leukorrhea, and the amount of blood is variable. This kind of leukorrhea should be alert to the possibility of malignant tumour such as cervical cancer and uterine cancer. In addition, cervical polyps, submucous fibroids and senile vaginitis can also have bloody leucorrhoea.

　　4, yellow watery leucorrhoea. It is mostly due to necrosis or denaturation of diseased tissues. For those with persistent bleeding, advanced cervical cancer, endometrial cancer or submucous fibroid with infection should be considered. Those with paroxysmal discharge should pay attention to the possibility of tubal cancer.

　　Clear and sticky leucorrhoea. It is like clear nasal mucus, which is mostly seen in physically weak women. In the case of endometrial hyperplasia, or after the application of oestrogen drugs, similar leucorrhoea increase can occur.

　　In short, there are many causes of abnormal leucorrhoea, once found above various pathological leucorrhoea should go to the hospital in time for examination.
