Delayed menstruation - when to sound the alarm?


Delayed menstruation delay menstruation can occur for various reasons, including the expense of physical and mental stress, disease, weight loss and so on, because the menstrual cycle - is the result of a joint "work" of the endocrine and nervoussystems that can change their activity due to various reasons.

woman's menstrual cycle

menstrual cycle is different for every woman.But more often it lasts 28 days, decreasing in some cases up to 21 days and increasing to 35 days.The entire menstrual cycle is divided into three periods:

  • oocyte maturation in the follicle (bubble) of the ovary (the first 15 days from the first day of menstruation), during this period the most active female sex hormone estrogen, which helps to mature the egg;
  • ovulation - rupture of the follicle and release of the egg from the ovary into the fallopian tubes;It usually happens on the 15th day of the menstrual cycle days of the menstrual cycle: Four phases The days of the menstrual cycle: Four phases under the influence of pituitary hormones (the main endocrine glands, located in the brain), which are included in the job when there is a need in the blood levels of estrogen;
  • period luteum - on the site of the ruptured follicle 16-17 day cycle formed by the corpus luteum, which begins to produce progesterone and estrogen, which are under the influence of the uterus prepares for pregnancy;If pregnancy does not occur, the corpus luteum ceases to function, the level of sex hormones falls on 28-29 day begins rejection is already prepared to receive the embryo of the mucous membrane of the uterus, which is accompanied by bleeding (menstruation).

Menstruation normally

In normal menstruation occurs on the 29th day from the beginning of the last menstrual period, the same day as the first day of a new menstrual cycle.In just a few days before menstruation may appear slight pain in the lower abdomen, breast engorgement and some irritability Irritability - Try to control your mood Irritability - you try to control my temper .Menstrual bleeding lasts from three days to a week, the most intense bleeding is common in the first three days, after which the discharge becomes negligible.

why delay may occur monthly

delay menstruation can occur when:

  • menstrual disorders of central origin, such as acute and chronic stress;
  • violation ovarian activity due to various reasons;
  • after a traumatic effect on the mucous membrane of the uterus (after abortion, childbirth or surgery on the uterus).

At a delay menstruation over a week to see a doctor and find out the cause of this phenomenon.

Menstrual disorders of central origin

under stress, brain injuries, endocrine diseases, tumors, high physical activity (for example, during sporting events) and other influences may suffer and production of hormones, the menstrual cycle to ensure job.This primarily affected production of pituitary hormones (the main endocrine gland located in the brain), which contributes to delay ovulation, the follicle has matured.With the defeat of the hypothalamus (region of the brain responsible for the activities of the entire endocrine system) violated the regulation of ovarian follicular development ceases.

Menstrual disorders associated with the activity of the ovaries

failures may occur at the level of the ovary.Under the influence of various factors (stress, common diseases, diseases of the female genital organs, tumors, harmful effects of metabolic disorders on a background of strict diets for weight loss and so on) fails to develop estrogen and progesterone, which also entails a violation of the menstrual cycle.If time does not pay attention to the delay monthly, it can cause a serious violation of hormonal background.

Menstrual disorders associated with a traumatic effect on the mucous membrane of the uterus

Such violations often occur after abortion or childbirth.While abortion occurs scraping Scraping - heavy and unsafe procedure Scraping - heavy and unsafe procedure mucosa together with the embryo, then the mucous membrane is not immediately restored, which is the reason for the delay period.After delivery, delay menstruation is not just due to injury of the uterine lining, but also due to prolactin (a hormone that promotes the development of breast milk), which prevents the development of estrogen.

delay menstruation pregnancy

Of course, the most important reason for the delay menstruation - a pregnancy.When it occurs, the corpus luteum, which was formed on the site of the ruptured follicle begins to actively produce progesterone Progesterone - norm and pathology Progesterone - norm and pathology , which prevents the maturation of new follicles in the ovary and helps to increase the endometrium, necessary for the implementation of the embryo.If pregnancy is suspected, you will need to buy at the pharmacy a home pregnancy test and then consult a doctor.

Remember: the menstrual cycle - is a delicate process, to support the fertility of women, he may suffer from any impact, so if you delay menstruation is better to consult a doctor.
