Too much vitamin A can make you sick but it will not affect your menstrual cycle. Vitamin A has no bearing at all on your monthly cycle, but it is useful for your vision, teeth, skin and skeletal and soft tissue. Ask your doctor how much vitamin A you need before you start to take supplements.
Hypervitaminosis A
Hypervitaminosis A is the medical term that is used to describe when you get too much vitamin A. Too much vitamin A can cause side effects such as blurred vision, abnormal softening of the skull, increased intracranial pressure, liver damage, hair loss, sensitivity to light, vomiting, drowsiness, dizziness and bone pain or swelling. Too much vitamin A can also turn your skin yellow or orange and lead to skin peeling and itching.
Natural Amenorrhea
Amenorrhea is the absence of your menstrual cycle. There are reasons that occur naturally that would make your period stop. During pregnancy, women lose their period since the uterine lining does not shed during this time. If you are exclusively breastfeeding your periods will stop. Your period may return if you stop breastfeeding or if your baby begins eating solid foods, and therefore breastfeeds less often. When you begin to produce less milk, this prompts the return of your menstrual cycle. Women experiencing menopause will also lose their menstrual cycles, again due to the uterine lining not shedding.
Medications and Amenorrhea
Certain medications -- such as antidepressants, blood pressure drugs, chemotherapy drugs and antipsychotics -- can cause amenorrhea. Certain contraceptives may also stop your periods. Some women who take oral contraceptives may not have their period, or depending upon the type of oral contraceptive, you may only have a period once every three months. Contraceptives that are implanted or injected, such as an IUD or the Depo Provera shot, may cause your period to cease.
Other Causes
Stress, excessive exercise and a low body weight can cause your periods to stop, according to MayoClinic.com. A hormonal imbalance, such as polycystic ovary syndrome, a thyroid imbalance and a pituitary tumor can also cause amenorrhea. Premature menopause, which typically occurs between the ages of 45 to 55, can cause your periods to stop. A structural problem, such as uterine scarring, a lack of reproductive organs or a structural abnormality of the vagina can also cause amenorrhea.
