why do you have a miscarriage


It is estimated that nearly half of all pregnancies end in miscarriage - many occurring a few weeks after conception. Once a woman knows she is pregnant, the risk of miscarriage is 15-20 percent, most of it occurs in an October 1 weeks.That experience horribly wrong for a process of life and the old baby-making. The question of why teen pregnancy is so dangerous has intrigued scientists and doctors from long ago. Recently, however, clearer answers. Miscarriages can occur for many reasons, such as hormonal problems that affect the mix of chemicals in the body of the mother, a physical problem with your reproductive system, or infection in early embryonic development. Obesity and caffeine consumption were also associated with pregnancy loss.

More on abortion:

But the blame for at least half of miscarriages is beyond the control of a mother and often nothing to do with his health or his life. Chromosomal abnormalities the addition or subtraction of light from the set of 46 chromosomes, the packages or package DNA in the cells of a fetus are responsible for most of the pregnancies were stopped. In fact, some research has found that defective chromosomes are up to 80 percent of spontaneous abortions in the first few weeks if the mother is more 35.When I talk to friends who have had miscarriages, the question of why and what happened seems to persist with them - that is understandable. However, the confidence (or annoying, depending on how you look) is that most of the time, chromosomes are totally random drawbacks. Generally, they have nothing to do with mom or dad genes, and not touch a good chance that a couple have a perfectly healthy pregnancy in the future.

However, humans were the creation of the life of the egg and sperm for thousands of years, probably to improve the process of walking. Therefore, in our modern world, why so many embryos suffer fatal chromosomal seeds /Earlier this year, investigators received a peek at the answer to this idea by studying mice (with a child process is the same as ours) and see what happens before that the sperm find the egg. In Current Biology, the researchers reported that the process in which the egg is usually the problem. Normally, when the egg cells to divide and be prepared to fill the other half, creating two side-by-side up on line 23 chromosomes (46 total) - two lanes in the center of the cell's genetic. When everything is in order, the chemical symbol indicates the cell has time share and each daughter cell ends up in the 23 Later, when the sperm enters the scene in their own 23, the gene pool was ready.

But often, the signal, called the checkpoint of the entire axis, jump the gun and told the egg to divide primarily a tail. This means that a daughter cell has 24 chromosomes and 22 to - anyway, if the sperm is one of those eggs, the numbers are off. Fertilized eggs begin to divide and grow, but can not go very far, and there is a miscarriage. The only exception is when the number of off-turns out to be an extra chromosome 21, in which case the fetus may prosper, but the baby has Down syndrome. As a woman ages, the signal seems to have more trigger-happy (and thus increases the risk of chromosome problems with age), but the faux pas that can happen to a woman of 20 years, too. Scientists wonder if evolution has brought the eggs to slide errors because they are so valuable: it is better to let it divide and play instead of keeping them tied up and unavailable. Sperm, on the other hand, seem to have more of a system of strict quality control.

Of course, knowing the biology involved did not make it easier for couples who lose a pregnancy. But it helps to explain why miscarriages are so common in many cases not related to anything the mother or not in the first weeks. True, to put the odds of a healthy pregnancy for us, women are recommended to be healthy themselves and start taking vitamins before a baby is made. But in the end, for a large number of pregnancies, there is a force sensitive and involved the arbitrary nature of things that can lead astray, and for the most part, this part of the process is completely out of our hands.
