What is amenorrhea?
Amenorrhea is the medical term for absent menses (no period). Missing a single period is not considered as amenorrhea although this should not occur in a healthy female unless there are short term disturbances. Amenorrhea is a total lack of menstruation that occurs for 6 months or more. There are two types of amenorrhea – primary and secondary amenorrhea.
Types of Amenorrhea
Primary amenorrhea is the lack of menstruation in a girl who is 16 years or older or if there are signs of puberty present for more than 2 years with no menses. This means that menarche (the onset of menstruation) has not occurred as yet under the the abovementioned conditions.
Secondary amenorrhea is when menses is absent for 6 consecutive months or more in a girl or woman who was previously menstruating. Pregnancy and menopause are two common causes that are not pathological but there are other causes that may be a result of minor or serious medical conditions.
