It is known to all that emesis is one of common responses of pregnant women at the early stage of pregnancy.
The reasons of causing gestational emesis have still not been found out in the field of medical science.
People have been always trying various ways to alleviate the emesis.
Pregnant women should know quite clearly that drugs can not be used to stop the emesis, or the health of the fetuses can be endangered.
Ginger plays an important role in alleviating the gestational emesis for women.
If some pregnant women always vomit seriously, they can make use of ginger to alleviate the emesis.
In recent years, according to the medical research, some experts in European countries have come up with their own views that gestational emesis is in fact a kind of self-defense behavior of the fetuses to prevent the harms of toxic substances for themselves.
This kind of opinion is relatively new in the field of medical science.
The foods we eat in our daily life usually contain some different toxic substances which can endanger the human health to varying degrees.
These toxins can not seriously and directly endanger the health for normal people, and it is difficult for normal people to make any response immediately after they eat these foods.
However, the fetuses in the bodies of pregnant women can not bear these toxins.
When these toxins enter the embryo, the normal growth of the fetuses can be affected.
Therefore, the fetuses can make the body secrete two kinds of hormones including estradiol and acetone.
What's more, the secretion amount is 5 times higher than the normal one, which can make the sense of smell of expectant mothers become sensitive.
As long as expectant mothers smell out something frowzy, emesis can be caused so as to prevent the toxins from entering the body.
In addition, the appetite of pregnant women at the early stage of pregnancy is usually bad and the foods they eat can stay long in the body.
Therefore, there is adequate time for the body to check the toxins contained in the foods.
Once the toxins are found, they can be removed by the sensitive emesis of expectant mothers.
The experts advise that pregnant women should not be worried about gestational emesis too much, and they should keep a happy mood and adjust the diet in time so as to supplement enough nutrients for their bodies and the fetuses.
