When women miss consecutive 3 periods or when girls do not get menstrual periods till the age of 16, it is called amenorrhea. It is of two types – primary amenorrhea and secondary amenorrhea. Primary amenorrhea is absence of menstrual bleeding in a girl by the age of 16 years with normal development of all the other secondary sexual characters and secondary amenorrhea is absence of menstrual bleeding in a women more than 3 months without any pregnancy and lactation.
Pregnancy is the major cause of amenorrhea. Further reasons can be problems associated with the reproductive organs or hormone regulating glands.

Following are natural reasons of amenorrhea which occur in the regular course of a woman’s life may alter the menstruation cycle:
When a women is pregnant, she misses periods.
Breastfeeding also leads to change in the cycle of menstruation
Menopause is also a reason.
Women may miss periods who consume contraceptive pills. Normal ovulation and periods may take 3-6 months to restart when the birth control pills intake is stopped.
Few antidepressants, chemotherapy, blood pressure and antipsychotic drugs may lead to stopping of menstrual periods.
4. Lifestyle factors
Several lifestyle factors are also the cause of amenorrhea. These can be:
Function of hypothalamus is altered by stress. Hypothalamus controls the menstrual cycle regulating hormones. Due to this, ovulation and menstruation might stop. When the stress is reduced or eradicated, the periods start.

c. A lot of exercise
Women who are involved in gymnastics, running, ballet have to undergo a lot of extensive training. These women face the problem of stopping of periods. Low body fat and spending a lot of energy can be a cause of this.
5. Hormonal imbalance
Some medical problems like thyroid malfunction, pituitary tumor, polycystic ovary syndrome or premature menopause cause a lot of hormonal imbalance, thus altering or stopping the period cycle.
6. Structural problems
At times, the sexual organs face some problems thus causing amenorrhea. These are:
a. Absence of reproductive organs. Some girls, due to problems during development of the fetus, do not have reproductive system’s major parts (cervix, uterus or vagina). So they do not have menstrual cycles.
b. Abnormality in the structure of the vagina. Menstrual bleeding is not visible, when there is barrier in the path of the vagina. This is due to some membrane which blocks the flow of the fluid.
