Amenorrhea is defined as the absence of menstruation for a period of time longer than 90 days. It may be normal (physiological) or be indicative of disease (pathological).


Menstruation, or period "rule" is bleeding from the vagina from the uterus, and represents the beginning of the female sexual cycle ormenstrual cycle, approximately 28 days and usually occursfrom the 10-14 years of age and lasts until menopause.
physiological amenorrhoea

The lack of menstruation is physiological when:

• The lack of menstruation is before puberty, the first menstruationusually occurs between 10 and 14.
• In pregnancy: amenorrhea is always present.
• In the lactation amenorrhea that occurs during lactation is ofhypothalamic-pituitary and is of variable duration. The endometriumdoes not grow or develop due to decreased production of hormones. This is because there is no maturation of ovarian follicles.
• At menopause, that starts between 45 and 55. This is because the ovary loses functionality. Begins to occur when hormone secretionis no longer rhythmic.

Pathological amenorrhea: 
Due to a functional alteration of the physiology or organic female. Depending on the altered physiological stage are:

• Peripheral amenorrhea (genital tract).
• amenorrhea gonadal.
• Pituitary amenorrhea.
• amenorrhea hypothalamic.
• amenorrhea adrenal and / or thyroid.


There are many reasons for the filing of a hemorrhage after the first menstruation. Nutritional factors, tumor, stress, emotional trauma, anovulation, immaturity of the hypothalamus, etc.. are possible causes, but it is very important to go immediately to your gynecologist to prevent any complications.
