However, increased leucorrhea is not the only symptom of menstruation, as it can be caused by a variety of factors, such as vaginitis, cervicitis, pelvic inflammatory disease and other gynecological diseases. If the leukorrhea increases when the menstruation is about to start, but there are no other abnormal symptoms, then it means that the menstruation is about to start. However, if there is an increase in the amount of leucorrhea and a yellowish color of the leucorrhea, then it may be caused by a series of other diseases such as chronic cervicitis or pelvic inflammatory disease or adnexitis. In this case, you need to go to the hospital for routine leucorrhea, electronic colposcopy and ultrasound examination of the uterine appendages to identify the specific cause of the disease, and then timely treatment, do not wait for the further development of inflammation, leading to more serious consequences. The leucorrhea increases during the pre-menstrual period and returns to normal after the menstrual period, which is also a physiological phenomenon. But if the amount of leucorrhea is still a lot after the menstruation, it should be taken seriously to prevent gynecological inflammation. The woman in daily life should strengthen physical exercise, improve their own resistance and immunity, usually do not engage in high-risk sexual activity.
