There are actually many reasons for premature birth, in order, such as from the perspective of the pregnant woman herself, relatively thin, very thin people, may have a greater chance of premature birth. Or the age of pregnant women is relatively small, of course, especially the elderly may also be easy. In addition, the nutritional status of pregnant women is not very good, malnutrition, as well as the usual eating habits, there are some bad habits, such as frequent smoking, drinking, these conditions may be a factor in premature birth.
In addition, if you have had a history of preterm birth in the past, you have had a history of preterm birth once or twice, and the probability of re-birth next time may be much higher than that of the ordinary population. There is also a cervical cone like doing it now, there is a little cervical lesion, cervical cone incision, and now the cone surgery is more excessive, such a crowd is particularly large, the cervix is short, and the incidence of preterm birth may be high.
There are also some people, such as the last premature birth, the diagnosis is caused by cervical insufficiency, this pregnancy, the cervix will automatically dilate, more likely to occur premature birth. There is also a very important, that is, after the last pregnancy, when to get pregnant next time, the interval time is also very important, some people are very anxious, two or three months to start pregnant, in this case, the probability of premature birth may be high. Therefore, it is generally recommended that the interval be at least six months or more, which may be relatively safe.
Then there may be this pregnancy, such as twins, or too much amniotic fluid, or the child is too large, in short, these conditions, are leading to excessive dilation of the uterus, the tension of the uterus is relatively large, of course, it is easy to produce premature birth, overdistention is not ok, it will cause contractions. Or there are infectious diseases of the reproductive tract, premature birth is actually the largest relationship with infection, reproductive tract infection, of course, the infection of the whole body is generally very small, mainly or the infection of the genital tract, especially like premature rupture of membranes in preterm birth, premature rupture of membranes in most cases, in fact, there is an infection first, only caused by premature rupture of membranes, so this is a large group of diseases that are more closely related to preterm birth.
There may be some complications, such as pregnancy hypertrophy, diabetes, there may be some problems, the need to terminate the pregnancy early, is the so-called iatrogenic preterm birth, are some of the causes of preterm birth, probably these.
