If a female plantagenarian has not reached menopause, she will have her period under the action of estrogen and progesterone in her body. Menstruation, or menstruation, is the cyclical shedding of the uterine lining in response to estrogen and progesterone, resulting in vaginal bleeding. Although most vegetative patients do not have cognitive and activity ability, their brainstem and most of their organs are functioning normally. If a female vegetative patient is not yet menopausal and has normal endocrine levels in her body, the endometrial lining of the uterus may proliferate and shed, resulting in menstruation. During menstruation of female vegetative patients, attention should be paid to the removal of menstrual blood and vulvar cleansing to avoid infection causing adverse consequences. If irregular menstruation occurs or menstruation disappears, there may be endocrine disorders, and you can go to the hospital for standardized diagnosis and treatment in time.
