The decrease in leukorrhea that occurs during perimenopause is due to lower levels of estrogen in the body. Perimenopause is generally defined as the period of a woman’s history before and after menopause (usually from about 45 years of age to 12 months after menopause), which includes the emergence of the biological, endocrine, and clinical features associated with menopause from the time of approaching menopause up to 1 year after the last menstrual period. Leukorrhea is a mixture of exudate from the vaginal mucosa, cervical canal, and endometrial glandular secretions associated with estrogen action. Perimenopause marks the decline of ovarian function and is a period of normal physiological change. It is a normal period of physiological change and should be managed through lifestyle habits or psychological and medication treatments to smooth out this special phase. If you want to take medication, you should standardize the use of medication under the guidance of a professional doctor to avoid adverse consequences.
