However, only 1% of them are actually considered severe morning sickness and require medical help.
The cause of morning sickness in pregnancy has so far not found a clear mechanism. Some theories have been put forward to be due to physiological hormonal changes during pregnancy. In particular, when the level of progesterone increases, it will relax the muscles of the digestive system, leading to food in the stomach being pushed up into the esophagus, creating a feeling of nausea. This substance also makes food in the stomach digested more slowly than usual, causing indigestion. In addition, some women with a sensitive nervous system will react very strongly to changes in the body, especially during pregnancy.

In addition, it is also important to clearly establish that morning sickness is not a "sign" of good or bad pregnancy and does not reflect anything about the development of the baby as well as help assess the situation. maternal health. However, if the mother has dehydration, severe electrolyte disturbances due to vomiting, severe weight loss is alarming and should be hospitalized for timely intervention. In cases where morning sickness affects the mother's life, an indication to terminate the pregnancy may be given.

After the hard days of pregnancy, most women will feel some relief by week 16. Only a small number (about 10%) will experience nausea and vomiting that persists throughout pregnancy until delivery. .
