During pregnancy a woman's body there are numerous changes necessary to ensure that a woman was able to bear a child. And after birth, these authorities are gradually coming back to normal. And, of course, most of the changes it is undergoing cancer. Yes, and complications are more likely to - the uterus after childbirth sometimes comes in the form of far right.
This is what will be discussed in this article. However, in order to get a complete picture of what is happening to the uterus after childbirth, and what complications can trap the postnatal period, it is necessary to know exactly how it changes during labor. Then clear everything will be much easier and therefore the time to notice the problem.
What is cancer?
First, let's refresh your memory a little bit of knowledge about what is the uterus. Doctors call the uterus hollow muscular organ of the female reproductive system. The uterus is a unique body of its kind - in her developing fetus, because of what the size of the uterus during pregnancy increases ten times, coming back after childbirth to their original positions.
The uterus is composed of two main parts - the very body of the uterus, which is located in the pelvis and the cervix. The body and the cervix are separated by an intermediate tissue, which is called the isthmus. The uterus is pear-shaped, is neck down. And the highest point of the uterus is called the bottom of the uterus.
Uterine walls themselves are comprised of three different layers:
- The outer layer of the uterus - the perimeter, which is also called serosa.
- The inner layer of the uterus - the endometrium.
Uterine mucosa changing its structure depending on which phase is in the menstrual cycle. If fertilization has occurred, the endometrium becomes more friable, that fertilized egg could easily be implanted in her. And the nutrients and oxygen to the first, is not formed and the start of fully functional placenta also provides the ovum is the endometrium. If pregnancy does not occur, the mucous membrane of the uterus (endometrium) is separated from the walls and removed from the uterus with menstrual secretions.
- Finally, the middle, an intermediate layer of the uterus - myometrium.
The myometrium is the main part of the body of the uterus, and it allows the uterus to grow so much in size during gestation baby. During this period, the mother takes the bulk of the layer changes in some way related to pregnancy.
To the uterus could be increased as the child grows, muscle cells - myocytes begin to rapidly divide, thus forming, muscle fibers. Moreover, the growth of the uterus and has provided thickening and lengthening of the muscle fibers. Incidentally, this is more even during the first half of pregnancy.
Normally, a woman of reproductive age is the womb of approximately 8 cm and a thickness - about 5. If a woman has never given birth, the weight of her uterus is about 50 grams, and have already given birth - about 100 centimeters. At the end of the pregnancy uterine size increases very strongly - at length becomes about 38 centimeters, and its weight without membranes and child - about 1,200 grams. In the same case, if the expectant mother polyhydramnios or the Multiple pregnancy, the weight of the uterus can be even more - up to 1500 - 1800 grams.
The uterus begins to increase at about 6 weeks of pregnancy - this corresponds to the second week of delay the onset of menstruation. And at first the uterus increases gradually - first, it increases in size, anteroposterior, and then, after a short time - and in the cross.
In the first weeks of pregnancy by palpation the doctor determines the asymmetry of the uterus - one of its corners bulging stronger than the other. This is due to the protrusion of the fact that in this place stuck fertilized egg, which is growing rapidly. Just a few weeks fertilized egg becomes large enough to fill the entire cavity of the uterus, which will get a symmetrical shape.
By the end of the eighth week of pregnancy in uterine size increases twice, and after only two weeks - three times already. By the end of the first trimester - 12 weeks of pregnancy, the uterus is increased four times in and out of a small basin, the upper edge of the symphysis pubis.
Study size of the uterus
To the doctor can determine if a pregnancy occurs, the physician should evaluate the status of the uterus, its size and density. This requires a two-handed examination of the uterus. To do this, the doctor inserts into a woman's vagina middle and index fingers of his right hand. A doctor with his left hand very gently and gently press on the anterior abdominal wall. Bringing the fingers of both hands, the doctor will feel the body of the uterus, to determine its anatomical features.
However, remember that this method of determining the size of the uterus is relevant only in the first twelve weeks of pregnancy. Thereafter, the uterus beyond the lower edge of the pelvic organs, so the doctor can feel it through the abdominal wall. It is from this time, the doctor begins to measure abdominal circumference and height of standing uterus. Shorten is a concept called "AMD".
To measure the circumference of the abdomen and AMD, your doctor will need either tazomera, or at least an ordinary tape measure. Before examining expectant mother must go to the toilet and empty the bladder. During all of these measurements the woman should lie on his back.
In order to assess pregnancy and fetal development, doctors compared the figures obtained with the established and generally accepted standards. However, remember that as if it was, but it is only average data, so in each case, the doctor in evaluating the condition of the uterus will certainly take into account the individual characteristics of each woman - her body, during pregnancy and more.
However, average figures do exist, and they must be taken into consideration - a deviation of more than five centimeters a cause for serious concern:
- 16 weeks of pregnancy - WYD is about 6 - 7 cm.
- 20 weeks of pregnancy - WYD is about 12 - 13 centimeters.
- 24 weeks of pregnancy - WYD is about 22 - 23 centimeters.
- 28 weeks of pregnancy - AMD is about 25 - 27 centimeters.
- 32 weeks of pregnancy - AMD is about 30 centimeters.
- 36 weeks of pregnancy - AMD is about 33 centimeters.
- 38 - 40 weeks of pregnancy, the uterus is significantly lowered, and AMD is about 28 centimeters.
As mentioned above, the height of standing uterus - is not a constant. It can affect the amount of amniotic fluid, the amount of the unborn child - stretching of the uterus, in this case more strongly, and therefore the height of the uterus is larger than in normal pregnancy. Equally important is the presentation of the fetus - if it is a cross or skew, then AMD will be less than usual.
That is why doctors - gynecologists almost never determine the gestational age at the height of standing uterus. Therefore, we take into account such factors as the beginning of the baby move, the date of the last menstrual period, the results of ultrasound examination of the fetus.
The increase in size of the uterus
In that case, if the pregnancy proceeds normally, the woman almost does not feel the increase in size of the uterus, because it occurs gradually. However, at the beginning of pregnancy, a woman may feel quite strange sensations in the lower abdomen - this is due to the fact that the structure of the uterine ligaments begins to change rapidly, soften.
In the same case, if the uterus begins to grow too quickly - because of polyhydramnios or multiple pregnancy, or if the woman has a uterus deviates posteriorly, or if the uterus of a woman has uterine scars (for example, by cesarean section), or if a woman has adhesions, often a woman begins to experience pain, sometimes quite strong.
Often, many women hear advice to endure the pain, allegedly because it is normal and physiological. However, doctors - gynecologists advise expectant mother does not tolerate the pain, and at the first of its manifestations, seek medical attention. Only a doctor can realistically assess the status of women and the cause of which led to pain. Otherwise she risks not pay much attention to the pain, which signals the beginning of spontaneous abortion - abortion.
Strictly speaking, no pregnant woman or have given birth in any case inadmissible attempt to deliver a diagnosis. Often, even the most experienced doctor takes time and some additional research in order to ascertain the exact diagnosis. And if a woman has a doctor and asked for help out of time, the most precious time can be irretrievably lost.
What happens to the uterus after childbirth?
What happens to the uterus after childbirth? Contractions of the uterus after delivery starts within a few minutes after the birth of the child. Immediately after birth the intense contraction of the uterus begins to happen to the wall separated from her and walked the last. In the first few hours after birth height of uterine fundus is approximately twenty centimeters. Further, the uterus will fall by about one centimeter a day for about two weeks.
In that case, if the contraction of the uterus after childbirth occurs normally, the indicators will be approximately as follows:
- 2nd day after birth - WYD is about 14 - 15 centimeters.
- 4th day after birth - WYD is about 11 centimeters.
- 6th day after birth - WYD is about 9 centimeters.
- 8th day after birth - AMD is about 7 centimeters.
- The 10th day after birth - AMD is about 6 centimeters.
The final shape will restore the uterus only the eighth - ninth week after the birth. However, in this case it is necessary to take into account some of the individual factors that can affect this process: characteristics of pregnancy and childbirth, breast-feeding a baby, the woman's age, the presence of certain chronic diseases.
As a rule, women older than 25 years or have not giving birth for the first time, or those who have had multiple pregnancies or polyhydramnios, the uterus can be reduced much more slowly. This means that the data for women may need medical intervention. The doctor will examine the woman, and if necessary it will appoint a special medication and physiotherapy, which will stimulate a more intense uterine contractions.
As long as a woman is in the hospital, the doctor is able to control the speed of the reduction of the uterus. However, the uterus contracts for a much longer time than is a woman after the birth in the maternity hospital. This means that certain problems can go unnoticed. That is why in any case inadmissible to ignore the preventive visit gynecologists.
A woman should undergo a pelvic examination in two weeks and one month after birth. The doctor will evaluate not only the uterus and cervix. Tragically, the cervix after childbirth can also leave much to be desired. But the young mother will need a lot of strength and health to take care of the most valuable, that only can be in his life - for his crumbs. But in the event that the problem is not noticed on time, very high risk of various complications due to which a woman can be in the hospital.
