Morning sickness is a normal phenomenon in pregnant women, but there are some women whose morning sickness time is different from that of most women. Does this difference mean that these women have physical problems? Although the symptoms of morning sickness may vary among pregnant women due to their different constitutions, let's take a look at what causes vomiting at 15 weeks of pregnancy.
This is normal, don't worry, many people's vomiting symptoms will persist until birth and gradually weaken as pregnancy progresses.
The main reasons for vomiting during pregnancy are as follows:
1. Morning sickness is a protective behavior
Morning sickness is a natural physiological response to protect the fetus in the womb. This instinct can detect various pathogens or harmful substances that may harm infants in advance, to ensure that these things do not enter the human body and avoid potential dangers.
2. Hormonal stimulation
Human chorionic gonadotropin is secreted from the villi of the fertilized egg during early pregnancy, and these hormones are absorbed by the mother. The secretion of progesterone is more obvious in early pregnancy, and pregnant mothers start at five or six weeks of pregnancy. The increase of estrogen during this period may also lead to morning sickness.
3. More sensitive sense of smell
During pregnancy, expectant mothers may be sensitive to various odors. Even if the smell comes from a faraway place or some less obvious odor, expectant mothers will immediately smell it and then experience nausea or vomiting reactions.
The above is a detailed introduction to what causes morning sickness at 15 weeks of pregnancy. We hope that pregnant women who think that prolonged morning sickness can be harmful can read the article carefully, understand the reasons for morning sickness, and understand that morning sickness can also vary due to individual physical differences, thereby reducing the tension caused by morning sickness.
