Amenorrhea - is the lack of menstruation for at least six months, the reasons for amenorrhea varied. Amenorrhea may be physiological (ie natural) and the pathological. In the latter case, in order to help women rebuild their reproductive function, it is necessary to establish the cause of amenorrhea.
Physiological amenorrhea - what is it
Physiological amenorrhea - is a variant of the normal functioning of the female organism. Periods may normally be absent during pregnancy, infant feeding
Breastfeeding - a personal choice
chest and during menopause. And if the first two reasons for women are not a surprise, the latter is often unexpected.
For example, some do not undergo menopause after 50 years old, and after 40-45 years. It occurs and is a variant of the norm. But in order to ensure that a woman must be examined, because the cause of early menopause may be pathological.
Pathologic amenorrhea - basic types
Pathologic amenorrhea - is the absence of menstruation, which developed due to some disease such as gynecological and general. Pathological amenorrhea can be divided into primary and secondary.
Primary amenorrhea - absence of menstruation is from the beginning, that is, after 15-16 years. Usually, the cause of amenorrhea is a kind of congenital abnormality.
Secondary amenorrhea - is the absence of menstruation for six months, provided that the earlier a woman has established menstrual cycle.
Causes of primary amenorrhea
Primary amenorrhea may occur with different genetic and congenital malformations. By the genetic anomalies are anomalies associated with abnormalities in chromosome apparatus. To identify such violations can only be by means of genetic research.
Congenital abnormalities may be associated with the peculiarities of functioning of neurohumoral system supporting the menstrual cycle, as well as with the anatomical structure of violations of the sexual organs.
Neurohumoral system that provides hormonal support of the menstrual cycle (and hence fertility) includes the cerebral cortex - the hypothalamus (a brain region responsible for the operation of the whole endocrine system) - the pituitary gland (the main endocrine gland, which regulates the activities of all the other endocrine glands ) and ovaries. Congenital imperfections on any of these levels can lead to the development of primary amenorrhea.
Finally, the cause of primary amenorrhea
Primary amenorrhea - a consequence of the genetic damage
It could be a congenital anomaly structure of genitalia - no uterus imperforate vagina or cervix, the opening in the absence of the hymen and so on. In this case we speak of a false amenorrhea, as the neuroendocrine system is functioning normally, the menstrual cycle is regulated, but menstrual blood can not flow out to the outside of the presence of obstacles.
Causes of secondary amenorrhea
Causes of secondary amenorrhea are more diverse. It may be irregularities in the cerebral cortex and hypothalamus due to severe neuro-psychiatric and physical activity, stress, poor nutrition (eg, frequent fasting, extreme diets). Sometimes, the development of amenorrhea lead long and hard for the common occurring chronic diseases (a consequence of intoxication). In young girls the cause of secondary amenorrhea may be sports, including sports, during which heavy physical activity combined with the stress.
The cause of secondary amenorrhea
Secondary amenorrhea - a dangerous norm?
can be diseases and tumors of the hypothalamus and pituitary gland. For example, the cause of amenorrhea can be a benign tumor of the pituitary gland secretes the hormone prolactin. Prolactin secretion of follicle-stimulating hormone delays the pituitary gland (FSH - it stands in the first half of the menstrual cycle), inhibits the maturation of the egg in the ovary, prolongs the existence of the corpus luteum and release of progesterone

, And hence the onset of menstruation.
Diseases and tumors of the ovaries may also cause menstrual disorders and amenorrhea. Such diseases include polycystic ovarian syndrome, resistance syndrome and depleted ovarian benign and malignant ovarian tumors.
Often a negative impact on the reproductive system of women have other endocrine glands, in the first place - the thyroid and adrenal glands. Diseases and tumors in these glands can also cause amenorrhea.
After suffering inflammation of the uterus, obstructed labor and abortion within the uterus may form adhesions that prevent leakage of menstrual blood. This amenorrhea is false.
The reasons are many amenorrhea. In order to help a woman restore normal reproductive function, all these factors need to be identified and eliminated.
