Why do not the periods begin?

Representatives of the weaker sex at different ages may be interested in the same question, which relates to why the menstruation does not begin. And if the young girls he cares much less often, then for women of reproductive age is often the reason for turning to a gynecologist. Let's look at the main situations that can lead to a lack of monthly ones.

What gynecological disorders can lead to a malfunction of the menstrual cycle?

The most common cause, which in turn is the answer to the question of why the periods do not start, if there is no pregnancy, is a hormonal background disorder. This kind of phenomenon is not uncommon in women of reproductive age.

So, a sharp change in the hormonal background, caused, for example, by the use of contraceptives, often leads to a cycle failure. That is why, it is commonly believed that the normal situation is the fact that at the beginning of taking hormonal contraceptives, a woman observes the absence of menstruation for 1-2 cycles. However, those women who are notified of this are much more likely to be interested in the doctor about why the menstrual period does not begin after the end of the contraceptive method. The whole point is that the normalization of the hormonal system of the female body also needs time. Most often it takes 2-4 months. It is during this period that various violations of the menstrual cycle, up to the absence of menstrual cycles, are possible.

If you directly speak about the diseases that lead to the development of amenorrhea, then among them it is necessary to distinguish:

• uterine myoma;
• ovarian cyst;
• cervical cancer;
• endometritis;
• adenomyosis ;
• infectious and inflammatory processes in the reproductive organs.

The possibility of presence in the body of these pathologies and is an explanation of why the menstruation does not begin, despite the fact that the pregnancy test is negative.

Talking about why do not start monthly for teenage girls, it is necessary to note the fact that the setting of the menstrual cycle usually takes 1.5-2 years, during which the menstrual period can be absent for a short time (1-2 months). This kind of phenomenon is considered the norm. However, it is not superfluous to consult with a gynecologist about this.

Prolactin amenorrhea, as a kind of absence of menstruation in young mothers

Quite often new moms are interested in the question as to why the men after the birth do not start for a long time. The thing is that after the appearance of crumbs in the body of his mother in a large concentration begins to synthesize the hormone prolactin, which is responsible for the secretion of milk. This hormone leads to inhibition of the ovulation process. It is because of this that a woman who has recently become a mother does not have a month's period.

The duration of this type of amenorrhea depends immediately on several factors, among which: the number of feedings per day, the frequency of application to the chest. They also have a direct effect on the concentration of prolactin in the bloodstream of the mother.

Because of what else the monthly can not be observed?

Often, amenorrhea may be due to a recent abortion. Explaining to the woman the fact that after the abortion does not begin monthly, doctors in the first place refer to the impossibility of rapid normalization of the hormonal system. This usually takes 2-3 months. During this time, basically, the cyclic, bloody discharge from the vagina is completely absent.
