During pregnancy, a woman's periods are absent, then there comes the physiological amenorrhea Physiological amenorrhea - at different stages of a woman's life .Pregnancy while developing normally.Women are often concerned about whether it is possible pregnancy if the woman has no menses?In most cases, no.
amenorrhea Amenorrhea - is the absence of menstruation for more than six months (if already established), or their absence from the start (there was no menstruation).In the first case we speak of primary amenorrhea, and the second - on the secondary.
amenorrhea also divided into physiological and pathological.Physiologically amenorrhea is a normal variant and develops during pregnancy, infant feeding Breastfeeding - a personal choice chest in children and older women.Pathologic amenorrhea develops when there are any failures in the neurohormonal system, women: the cerebral cortex - the hypothalamus - pituitary - ovary - uterus.
True called amenorrhea amenorrhea due to hormonal disruptions, false - changes in the anatomy of the uterus.
Amenorrhea and Pregnancy - physiological state
To understand why during pregnancy, there are no monthly, you need to know how to "work" woman's menstrual cycle.The menstrual cycle of women - a mechanism that allows a woman to have a baby.If it has a failure, the pregnancy or do not occur, or ends in miscarriage.
woman's menstrual cycle is divided into two phases, separated by ovulation.The first phase of the menstrual cycle is accompanied by the secretion of pituitary follicle-stimulating hormone (FSH), which promotes the maturation of egg follicles in the ovarian follicle cells and the secretion of female hormones estrogen.Under the influence of estrogen grows (proliferate) the mucous membrane of the uterus (the endometrium).
Once the ovum matures, this signal enters the central nervous system and the hypothalamus secretes a hormone that stimulates the secretion of other pituitary hormone - luteinizing hormone - LH.Under the influence of LH follicle in which the egg bursts and the egg is released from the ovary, heading into the fallopian tube for fertilization.Release of an egg from the ovary is called ovulation Ovulation - How to determine as accurately as possible? .
Once ovulation has occurred on the site of the ruptured follicle forms a new endocrine gland - the corpus luteum, it secretes the female sex hormone progesterone Progesterone - norm and pathology .Progesterone inhibits the proliferation of the endometrium and makes the last to secrete - secrete substances necessary to maintain the state of pregnancy.
If the egg is fertilized by sperm, then a week later it is gradually moving through the fallopian tube, embedded in the wall of the uterus, where he began to develop.Thus yellow body expands and releases many times more progesterone than before pregnancy - which prevents uterine contractions, which can lead to spontaneous abortion.It is understood that menstruation during pregnancy is not possible, because the menstrual rejected by the mucous membrane of the uterus, and together with it and implement it in the embryo, that is miscarriage begins.
If the pregnancy to the end of the menstrual cycle has not occurred, the corpus luteum gradually atrophies.Deprived of hormonal support the mucosa of the uterus is torn away, which is accompanied by menstrual bleeding.
amenorrhea and false pregnancy
Sometimes amenorrhea background, over which a woman is being treated, a so-called false pregnancy.The woman begins to feel pregnant, walking those actually conception has not occurred.The cause of false pregnancy is often a very strong woman's desire to have a child.Often this condition occurs in women after 35-40 years.
with developing indirect signs of pregnancy: increase breast, fat deposition in the abdomen and thigh, the phenomena of toxicity of the first half of pregnancy (nausea, vomiting, salivation).The belief of some women in the offensive of pregnancy is sometimes so great that they feel the fetal movements.
Naturally, such a condition can not last long, and the first medical examination dispels all doubts: the uterus is not increased in size, has all the same pear-shaped, the cervix has not acquired the characteristic bluish tint.
Persuade woman with a false pregnancy in her absence is very difficult.This requires a bedside manner, and sometimes mental health care.
amenorrhea and pregnancy - are two inseparable concepts.But amenorrhea during pregnancy is a physiological natural.Pathologic amenorrhea may also be a barrier to pregnancy.
