Causes amenorrhea !

A common cause of amenorrhea in young females sometimes overlooked or misunderstood by the individual and others, is an undiagnosed pregnancy. Amenorrhea in pregnancy is a normal physiological function. Occasionally, the same underlying problem can cause or contribute to either primary or secondary amenorrhea. For example, hypothalamic problems, anorexia or extreme exercise can play a major role in causing amenorrhea depending on the person's age and if she has experienced menarche.

Amenorrhea is the medical term for the absence of menstrual periods, either on a permanent or temporary basis. Amenorrhea can be classified as primary or secondary. In primary amenorrhea, menstrual periods have never begun (by age 16), whereas secondary amenorrhea is defined as the absence of menstrual periods for three consecutive cycles or a time period of more than six months in a woman who was previously menstruating.
