It is useless to take oral vitamin E for menstrual disorders, because vitamin E mainly has the function of assisting fertility, in addition to making the skin more elastic and skin shiny. Therefore, for women with menstrual disorders, oral vitamin E is useless. It is important to find out what causes menstrual disorders, whether they are caused by endocrine disorders or organic pathologies. It is recommended to have a blood test for sex hormone six on the second or third day of menstruation, and to check thyroid function, and then give the necessary medication according to the clinical results. In addition, certain diseases can cause irregular periods, such as polycystic ovary syndrome, or amenorrhea due to endometrial tuberculosis, which destroys the endometrial tissue. Therefore, patients with irregular menstruation must be examined and then given treatment.
