Amenorrhea: Delay of Menstruation
There are two types of amenorrhea. The first type is called primary amenorrhea and it occurs when a young woman hasn’t started her period by the age of 16. Secondary amenorrhea is when a woman who has already begun having regular menstrual cycles misses 3 or more periods.
Besides pregnancy there are many reasons why a woman may experience amenorrhea. For example, in primary amenorrhea, there are a host of physical conditions that may delay menstruation. The hypothalamus may have a disorder for instance. The hypothalamus regulates the menstrual cycle. Various stressors can impede the functions of the hypothalamus such as anorexia, psychological or physical stress, and excessive weight loss or exercise. Problems with the pituitary gland may also lead to absent of delayed menstruation. There may also be structural issues in the vagina that impede menstruation as well. A physician can detect these and other possible causes of primary amenorrhea.
Secondary amenorrhea can be the result of a pregnancy. It may also be a result of the use of certain contraceptives. For instance oral contraceptives may impede menstruation months after a woman stops taking them. That is also the case for contraceptives like Depo-Provera that are implanted. Stress is another important factor that can throw off a normal cycle as are medications. In addition, breast feeding can lead to amenorrhea.
There are several other conditions that can interfere with the menstrual cycle also. Hormonal problems, thyroid issues, excessive weight loss, too much exercising, tumors, or premature menopause is all implicated in amenorrhea. In many cases amenorrhea is resolved by itself. For instance, when amenorrhea is caused by stress or illness, when the conditions change positively menstruation often resumes its normal cycle. One of the most difficult aspects of amenorrhea is not knowing what is causing the problem. Consulting with a health professional can resolve much of the anxiety involved and also help find a solution, if one is available, to this problem.
