Lots of things -- if you are over weight your hormones can cause no periods, if you are underweight same thing. If you are an athlete you can over exercise : here's a great article about it:
The medical term used to describe "absence of periods" is amenorrhea. Women normally do not menstruate before puberty, during pregnancy, and after menopause. If a woman does not get her period when she normally should, it may be the symptom of a treatable medical condition.
There are two types of amenorrhea: primary amenorrhea and secondary amenorrhea. Primary amenorrhea is when a young woman has not had her first period by the age of 16. Secondary amenorrhea is when a woman who has had normal menstrual cycles stops getting her monthly period for 3 or more months.
What Causes Amenorrhea? Amenorrhea can be caused by any number of changes in the organs, glands, and hormones involved in menstruation.
Possible causes of primary amenorrhea (when a woman never gets her first period) include:
Failure of the ovaries (female sex organs that hold eggs). Problems in the central nervous system (brain and spinal cord) or the pituitary gland (a gland in the brain that makes hormones involved in menstruation). Poorly formed reproductive organs. In many cases, the cause of primary amenorrhea is not known.
Common causes of secondary amenorrhea (when a woman who has had normal periods stops getting them) include:
Pregnancy Breast feeding Stopping the use of birth control Menopause Some birth control methods, such as Depo-Provera Other causes of secondary amenorrhea include:
Stress Poor nutrition Depression Certain drugs Extreme weight loss Over-exercising Ongoing illness Sudden weight gain or being very overweight (obesity) Hormonal imbalance due to polycystic ovarian syndrome (PCOS) Thyroid gland disorders Tumors on the ovaries or brain (rare) A woman who has had her uterus or ovaries removed will also stop menstruating.
If your periods are absent or very irregular, you might have a hormonal imbalance and should see a doctor. It is not normal and it can affect way more than just your period. I found out I have PCOS and now I am on medicine for life.
