After menopause, the amount of vaginal discharge will significantly decrease, but a small amount of discharge may still be present, which is a normal phenomenon. Due to the significant reduction or disappearance of estrogen secretion after menopause, the secretions from the vagina and cervix will significantly decrease, thus reducing vaginal discharge. However, if there is an increase in discharge, a change to a yellow color, and itching of the vulva, it could be due to vaginitis, which requires prompt medical examination and treatment since vaginitis is relatively common in the elderly.
