The most common cause of increased leucorrhea after menopause may be due to the following reasons: 1. The most common cause is vaginal inflammation due to old age, because after menopause the vaginal mucosa becomes thinner and the local resistance is weakened, which can easily lead to pathogenic bacterial infection, resulting in increased leucorrhea due to local inflammation of the vagina, often accompanied by a burning sensation in the vagina or odorous discharge, etc. It is recommended to have a routine laboratory examination of the leucorrhea in a timely manner. 2. If the leucorrhea is like water, we should be highly alert to whether it is caused by fallopian tube cancer, cervical cancer or endometrial cancer. It is recommended to go to the hospital for gynecological examination, cervical cancer screening if necessary, and ultrasound examination to understand the corresponding clinical symptoms before giving treatment.
