What is the cause of pregnancy vomiting?

Pregnancy vomiting is considered to be related to the increased secretion of chorionic gonadotropin, estrogen and progesterone in the body.
After pregnancy, the hormones in the body will increase, causing a series of physical discomfort, such as nausea, vomiting, drowsiness, weakness, etc. It is usually physiological and will not affect the pregnant woman or the fetus.
It is recommended to choose light, easily digestible and non-greasy food in the diet, and drink yogurt in moderation, as yogurt contains probiotics, which helps digestion and can play a role in relieving pregnancy vomiting.
