Long Menstrual Cycle and Oligomenorrhea

Long menstrual cycles or oligomenorrhea are a common occurrence. The medical term is oligomenorrhea.

In fact most women will at least one episode of an irregular cycle during their menstruation years.

Some however have these regularly due to some medical condition.

Fortunately, the most common causes are rarely very serious. In fact, many of them require just lifestyle adjustment.

In this article, I discuss briefly the medical definition and common causes of long menstrual cycles.

What Is Oligomenorrhea?

A little background information on the characteristics of normal
cycle regularity will be helpful to understand the definition of
oligomenorrhea. The acceptable normal length of the menstrual cycle
should be within 21 to 35 days. This range also gives a range of 9 to
17 menstrual cycles each year. For example, if your cycles are 30 days,
you will have about 12 cycles each year( 366/30=12). The longer the
cycle length, the less menstrual cycles will occur in a 12 month period.
That is a woman having her periods every 34 days will have about 10 to
11 periods each year( 366/12=10.7).

What then is oligomenorrhea?
It is simply having less frequent menses because of a long cycle length
more than 35 days. If a woman’s periods come every 45 days, she will
have only about 8 menstrual cycles in a year. Therefor when the length
of the menstrual cycle is above normal( 35 days),it leads to
oligomenorrhea( oligo- means small or few).

Another loose meaning
of the term oligomenorrhea is its application to the volume of the
menstrual blood. Some writers and many women have used it to refer to
light menstruation. Others use the more appropriate medical term hypomenorrhea.

Causes Of Oligomenorrhea
