Can low iron in the body cause missed period?

No. Missing a period, means less blood loss which usually will cause less iron depletion. However in cases of severe malnutrition, such as seen with anorexia, a woman can stop menstruation and have low iron but it is not the cause. If your periods are less frequent and flow is not heavy, your doctor should check for other causes of low iron.

Hormonal imbalance. If you did not have sex since your last period, you are not pregnant. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD.
