Weight of the child

Weight of the child during pregnancy is an important indicator. The process of development of the child in the mother's body and flows through the rational one and the same rules for all women. But on the other hand, it is full of mysteries and secrets: the human mind is difficult to comprehend that just forty weeks from the cells, which can be seen only through a microscope, grows a real live baby.

Weight of the child in the I trimester of pregnancy (12 weeks) - the division of the cells and organs of the fetus tab

At the beginning of pregnancy, the fertilized egg begins to divide. This occurs immediately after fertilization, when the embryo has not yet reached the uterine cavity, but only moves toward it the fallopian tube. A week after conception Conception, ovarian cycle, fertilization and genetics of a child   it becomes embedded in the uterine wall, fix it and it will start to develop not only the body but the body that will "help" him to communicate with the mother - placenta. Around the emerging body of a child produced aqueous medium - amniotic fluid, the volume of which is very important for the proper development of the child. All together, this will be developed and characterized by different parameters, including weight.

Modern ultrasound equipment allows to determine the weight of the embryo in the earliest stages of development. Thus, it was found that at the age of 7 weeks it weighs about 3 grams, and has a body, a very large head and limb buds - all together it has a length of about 1 cm. It has already happened many organs tab. The body weight of the child at this time increases with great speed: in a week, it is 5 g, and a week later (ninth week of pregnancy - from that moment the embryo is called a fetus) - about 10 grams, that is, for two weeks the body weight of the child increases more than three times.

This is an active and differentiation of cells (ie they appear distinctive features characteristic of a particular tissue), bookmark and maturation of individual organs. This is a huge job that requires a very large amount of energy. It is not surprising that women in early pregnancy feels weakness and drowsiness.

By the tenth week, fetal weight is approximately 12 grams, the eleventh - 15 g, and the twelfth - 20 g By the end of I trimester of pregnancy when the pregnancy still is not noticeable to others, it is a little man. He has a head, eyes, nose, lips, ears, hands and feet with fingers. By this time the end the most dangerous period for the child - Share internal organs. This period is dangerous because any foreign substance received by the mother's body, can disrupt the process of laying of the child and any congenital malformations. Therefore, during the first 12 weeks of pregnancy in any case can not take any drugs, smoke, drink any alcoholic beverages (including beer).

Weight of the child in the II trimester of pregnancy (12-24 weeks) - the development of internal organs and systems

During this period, the increase in body weight of the child is not so fast: laying of over and began domestic "finishing work" - the development of the internal organs and systems. Since the growth rate of the fetus (and hence the energy costs) is somewhat reduced, the mother's condition improves. In addition, to the beginning of II trimester of pregnancy she had adapted to his condition, her health improved and the appearance of some women become even better than before pregnancy.

At the end of the thirteenth week of pregnancy the body weight of the fetus reaches 25 At that time has already been partially starts functioning placenta - organ that supports the connection between mother and child, and does not pass to the baby most of the toxic substances, that is, the fruit becomes more secure. He actively moves his weight significantly increases and sixteen weeks is approximately 120 grams at this time in the US can already distinguish boys from girls. At 17 weeks of the child's weight is 250 g, 20 - 280 g This is a small man with a big head still. In the next three weeks, the intensity of the weight gain of the fetus grows. By the end of the II trimester of pregnancy even before it reaches 650

Today is considered viable fetus weighing 500 grams or more, therefore, was born in this period of pregnancy the baby could survive if, of course, it will create the necessary conditions, that is, if the nursing home is the special equipment for the care of these children.

Weight of the child in the III trimester of pregnancy (from 25 weeks before delivery) - the completion of the maturation of the child

Next comes the "completion" of all organs and systems to normal and set the desired body weight. Weight of the child during this period is considerable, and the mother is getting heavier, especially if it has also its own weight. By the end of the twenty-eighth week of pregnancy, the child's body weight is equal to a little more than a kilogram. If the baby is born at this gestation, it has a better chance of surviving than 500 grams, as he has a viable internal organs. However, the body has such a child can not adjust the temperature, so survival is only possible in special incubator at a constant temperature.

At the end of the thirty-second week of the child's body weight is equal to 1600 g at the end of the thirty-sixth week - 2500 and the end of pregnancy - more than 3000 g This is a viable child, and he is ready to be born.

Should I plan a pregnancy?

Pregnancy should be planned primarily to the woman could give birth to a healthy baby. That is why before conception is necessary to accurately determine the condition of the health of future parents.

We begin with the therapist

3-4 months prior to conception, the woman must visit a therapist and to identify possible diseases. It is particularly important to identify diseases of the cardiovascular system (for example, high blood pressure), which can later cause severe complications in pregnant women. To detect hidden diseases need to be examined (blood, urine, etc.), for sanitation (prolechivaniya) chronic infection foci therapist will give referrals to other professionals, such as a dentist and otolaryngologist.

Visit the district obstetrician-gynecologist

It is better to visit it to the gynecologist, which you observed during pregnancy. The purpose of visit - the identification of defects and pelvic inflammatory disease, latent infections and other contraindications for pregnancy.

Inflammatory diseases should be treated, latent infections are identified and treated well.

What is latent infections

Hidden infections can occur, such as chlamydia, ureaplasmosis Ureaplasmosis - inflammation of the urogenital system , Mycoplasmosis, bacterial vaginosis Bacterial vaginosis - it harmless little gardnerella? Herpes virus. All of them are sexually transmitted and often women are not even aware of their existence. All of them can cause a number of complications during pregnancy and childbirth, as well as the impact on the health and future development of the child.

Therefore, all women who are preparing for pregnancy, should be tested for latent infection, and if it is, to be treated.

What threatens the blood incompatibility of mother and fetus

Before conception, both spouses need to determine blood type and the presence of her Rh factor. Blood incompatibility of mother and fetus Rh blood group or threatening emergence of hemolytic disease of the newborn. It is very dangerous.

Rh factor - a blood protein located on the surface of red blood cells (RBCs). Approximately 85% of people have Rh factor (Rh-positive are), and 15% do not have, they Rh-negative.

If a person's blood with a negative Rh factor gets Rh-positive blood, the body perceives the Rh factor as the enemy and begins to produce against him protection - antibodies that, when re-entering the body Rh factor, glued to it and removes it from the organism (Rhesus-conflict and clotting or hemolysis of the blood).

From this we can conclude that the first pregnancy in Rh-negative women are Rh-positive fetus is likely to end well, but again this pregnancy conflict is inevitable, so the interruption of the first pregnancy is undesirable. Pregnancy is Rh-negative fetus always end happily. Rh-negative man will never become a source of Rhesus-conflict.

Less hemolytic disease of the newborn caused by blood group incompatibility group of mother and fetus. At the same time due to an agglutinogen (A or B), present in the red blood cells of the fetus, but the absence of the mother, the maternal blood in the formation of antibodies Antibodies - "soldiers' immunity   to red blood cells of the fetus. Most immune incompatibility manifests itself in the presence of maternal blood group I, and the fetus - II, Group III less blood.

Identify possible genetic diseases

Expectant parents advisable to consult a physician-geneticist, who will help to identify the disease, the child can go by inheritance. To do this, a geneticist will ask first, what the parents are ill, and then - their close and distant relatives. Perhaps to clarify the situation will have to pass tests for karyotype analysis - sets of chromosomes, their number, size, shape and details of the structure.

If you are absolutely healthy

If in the process of a comprehensive examination (or after treatment) revealed that the parents are absolutely healthy, the obstetrician-gynecologist explains to the woman that may harm her or the unborn child.

Healthy lifestyle - it's not just words. Such things as sleep disorders Dreams: how to understand our dreams   and wakefulness, severe physical and mental stress, smoking, alcohol and drug use can not affect the health of both child and mother.

In preparation for pregnancy, a woman should be fully fed (no diets for weight loss!). Particularly useful are foods containing folic acid, which can prevent a variety of congenital diseases. Folic acid also contain foods such as legumes, nuts, greens, cabbage, carrots and potatoes.

In preparation to conceive woman has a lot of walking in the fresh air and do gymnastics.

It was always known that any disease is easier to prevent than to treat. This fully applies to the pregnancy.
