Leukorrhea is a mixture of vaginal mucous membrane exudate, cervical glandular secretions and endometrial glandular secretions. Women’s leucorrhea appears to be hanging like snot for a long time. Both physiological and disease factors can lead to the above situation: 1. Physiological factors: 1. close to ovulation: that is, about 14 days before the next menstrual period, the symptom may appear, which is due to the vigorous secretion of endocervical glandular cells and the gradual increase of cervical mucus, resulting in increased leucorrhea, which usually becomes sticky 2-3 days after ovulation. After that, it gradually decreases. 2. PMS: Due to pelvic congestion, the increase in vaginal mucosal exudate also leads to increased and thick leucorrhea. Usually, no treatment is needed, and it will not affect women’s body, as long as they pay attention to a light diet and avoid getting cold in the abdomen. Pathological factors: 1. Vaginal inflammation: For example, trichomonas vaginalis can cause the leucorrhea to become yellow or yellow-green in color and occasionally foamy. The typical feature of bacterial vaginosis is that the leucorrhea becomes gray or grayish yellow and has a distinct fishy or ammonia odor; for trichomoniasis patients can douche the vagina with lactic acid or acetic acid solution and take oral trichomone-killing drugs; for bacterial vaginosis, oral metronidazole and topical metronidazole suppositories can be used; 2, cervical diseases: such as endometritis, pelvic inflammatory disease, uterine fibroids, endometrial cancer, cervical cancer, etc. can cause leucorrhea in female patients. 2. Cervical diseases: such as endometritis, pelvic inflammatory disease, uterine fibroids, endometrial cancer, cervical cancer, etc. can lead to abnormal leucorrhea in female patients, which may appear like snot, or with the development of bloody leucorrhea, hard lumps and a foul smell. In addition to abnormal leucorrhea, patients may also experience abdominal pain, lumbar pain, vaginal itching, and frequent urination. Patients are advised to determine the location of the disease or tumor through a series of detailed examinations, and then carry out symptomatic treatment to prevent the disease from deteriorating. Among them, surgical excision is usually recommended for tumors, followed by chemotherapy or radiotherapy. For patients who are not suitable for surgical indications, combined chemotherapy and radiotherapy can be adopted in order to maximize the quality of life of patients. Since the vagina, urethra and anus are close to each other in women, bacterial infections can easily occur when they are not cleaned properly, so patients are advised to pay attention to personal hygiene, change their underwear regularly, and wash them with hot water. In addition, patients should pay attention to a healthy diet and sleep patterns to reduce the possibility of endocrine disorders and abnormal leucorrhea.
