This type of amenorrhea occurs latter in life when for apparently no reason, the menses are ceased. Sometimes a confusion is made because of another term : oligomenorrhea. Oligomenorrhea occurs when the menstruation appears after more than 35 days .
For a normal women the absence of the menstruation is not a usual thing and it needs some cause searching. There are though some exceptions in the case of women who present androgen excess such as virilization, sexual ambiguity or hirsutism..
The presence of amenorrhea does not depends on race or ethnic group but it does depends on some environmental factors like nutrition habits and the prevalence of chronic disease. For instance the growth of childhood obesity around the world is proportional with the growth of amenorrhea’s rate .
Secondary amenorrhea is more common and one of the causes is pregnancy because the lining remains to nourish the fetus. Although ovulation may occur, when a mother is breast feeding, menstruation may not. Another cause is the contraceptive pills. A woman who takes birth control pills may not have menstruation and it will take from 3 to 6 months after stopping the pills to resume regular menstruation . Anorexia or low body weight can also lead to amenorrhea because this affects many hormonal functions . Women who practice excessive sports and long term trainings may also suffer from this condition.
A common cause of amenorrhea is the polycystic ovary syndrome because it cases high level of estrogen and androgen that results in a decrease of pituitary hormones that lead to ovulation. This is also associated with obesity, acne, and facial hair .
A benign tumor in the pituitary gland can cause an overproduction of prolactin that will interfere with your menstruation . This tumor is treatable with medications but sometimes it requires surgery.
The treatment of secondary amenorrhea depends on the cause. It’s possible that the doctor will ask you to change your lifestyle, will ask you to eat healthy and to reduce the physical exercises.
Although amenorrhea is not a death causing condition it should be treated seriously .

More than 10% of the women evaluated for amenorrhea also have premature ovarian failure.
