Why does pregnancy cause vomiting?

Many mothers must have such doubts, why does vomiting occur during pregnancy? For mothers who are deeply "harmed" by "morning sickness", they must want to know the reason very much!

In fact, comprehensive consideration, the causes of vomiting during pregnancy are as follows:

After a woman becomes pregnant, the hormone secretion in her body increases, which can easily cause nausea and vomiting.

In addition, during pregnancy, a large amount of progesterone is secreted in the body to stabilize the uterus and reduce the contraction of uterine smooth muscles, but at the same time it will also affect the peristalsis of the gastrointestinal smooth muscles, causing indigestion, nausea, vomiting acid and other phenomena.

In addition to changes in physiological conditions, psychological factors can also cause morning sickness. After becoming pregnant, some women are unable to adapt to the physiological changes of pregnancy or are overly worried about the growth and development of the fetus, which leads to poor mental state and emotional instability. The psychological pressure is then converted into physical symptoms, causing nausea and vomiting.

Generally speaking, not all pregnant women will suffer from morning sickness, and the degree of morning sickness will vary greatly depending on the physical condition and mental state of the pregnant woman. Pregnant women with poor physical condition and who are more prone to tension will usually have more severe morning sickness symptoms.

Morning sickness usually lasts until the sixteenth week of pregnancy. After the sixteenth week, symptoms such as nausea and vomiting will gradually ease. Some pregnant women will experience weight loss during morning sickness, but because the nutrients needed by the baby in the early stages are limited, as long as the weight loss does not exceed 5% of the pre-pregnancy weight, it is still within an acceptable range and there is no need to worry too much.
