What are the causes of pregnancy vomiting?

Pregnancy vomiting is considered to be related to increased secretion of chorionic gonadotropin, oestrogen and progesterone in the body.
The increase in hormone levels in the body after pregnancy may cause a series of physical discomfort, including nausea, vomiting, drowsiness, body weakness and fatigue.
It is recommended to choose a light, easy-to-digest, non-greasy diet and to drink yoghurt in moderation. Yoghurt contains probiotics, which helps digestion and can help relieve pregnancy vomiting.
