Future generations are always frightened of women, especially if they are the first. And as is usually the unknown frightens, in order to add strength and self-confidence, you need to know more about what you expect. In antenatal clinics has always held training courses for childbirth - this is not a formality, but a vital necessity: prepared becomes the first woman physician assistant in childbirth. At the end of pregnancy is a kind of reorganization of the functions (and partly building) organs and systems of the women associated with the formation of the body's biological readiness to leave that ensures timely and correct approach during childbirth.
Important role in preparing the body for childbirth belongs to the female sex hormone estrogen, which give rise to the formation of the contractile protein actomyosin, softening of the cervix, uterus increase the sensitivity of muscle to the action of biologically active substances (oxytocin, acetylcholine, serotonin, and others.). Two weeks before a change in the ratio of delivery of certain types of estrogens: estriol concentration increases, and estradiol estrola
Estradiol, the most important hormone
The concentration of another female sex hormone - progesterone
Progesterone - norm and pathology
Which was very high throughout the pregnancy (progesterone inhibited the contractile movement of the muscles of the uterus) for the week before the birth falls, resulting in increased sensitivity of the muscles of the uterus to oxytocin - the base material, increases their contractile activity.
Increasing blood levels of aldosterone, which stimulates the formation of estrogens. Under the action of aldosterone increases blood volume. Ready to leave the body is supported by an active synthesis of adrenal hormones: produced in the adrenal cortex corticosteroids (they reduce tissue swelling and pain), and in the medulla - epinephrine and norepinephrine - hormones stress
How to beat stress? Create an oasis
Which prepare women to stress during childbirth. Increases blood concentration of prostaglandins, which are the main stimulants onset of labor.
What signs indicate that soon childbirth
Delayed symptoms occur in about two weeks before delivery, sometimes earlier. First of all, "the omission of the stomach" by insertion of the fetal head at the entrance of the pelvic floor and abnormalities of the uterus (fundus is at the top) in front of the decrease in the tone of the abdominal muscles. The woman then becomes easier to breathe, but more difficult to walk and sit, come back pain. Due to the fact that the increasing pressure on the bladder
Urinary bladder - structure and function
Can be frequent urination. Under the influence of hormones quickens and becomes more liquid stools.
Another sign of approaching childbirth - the emergence of increased excitability, or, on the contrary, complete indifference (apathy), "tides" to the head. This is due to changes of the central and autonomic (innervating blood vessels and internal organs) of the nervous system, and there is a few days before giving birth.
Body weight of pregnant 2-3 days before delivery falls to 1-2 kg - this is one of the stages of the body's natural preparation for childbirth, during which a woman eats little (reduced appetite).
Increases the excitability of the muscles of the uterus, which can manifest itself in the form of false labor. False contractions are different from the true fact that they are irregular and painful. Fetal movement, in contrast, is reduced due to the fact that it is becoming too small in the uterine cavity.
Because female genital tract for a few days before the birth leaves a thick sticky mucus - mucus plug. This mucus - the contents of the cervix, which closes the entrance to the uterus, thereby preventing penetration to the infection. Discharge of mucus plug indicates that the cervix is preparing for the disclosure and the formation of the birth canal. At the same time, the mucus plug can move ahead, for one to two weeks before the birth and is a variant of the norm.
What signs indicate that labor has begun and should be sent to the maternity hospital
First of all, the appearance of regular painful contractions. First bout is not accompanied by very severe pain, but gradually increases the intensity of their pain are very strong, unabated between contractions. The time between contractions is steadily declining, if in the beginning it was still about a quarter of an hour, just before birth - a few minutes. You should not really be afraid of fights, most often before birth is still a few hours (although there are also rapid delivery, which begin and proceed rapidly).
The second sign of the onset of labor - discharge of amniotic fluid. They can move away immediately, and can leak over time - everything is normal. Pain during this. Normally, amniotic fluid are transparent and odorless. If your water has broken (even if the fights yet), it is best to go to a maternity hospital and be under the supervision of a physician.
All the signs of the approaching onset of labor and need to know, not to be afraid and just call an ambulance to move to the maternity hospital.
