Clinically, it can be assumed that the presence of vomiting proves that there has not been an arrest of the fetus, and if the vomiting is still present, it proves that the embryo has not stopped developing clinically, but it is recommended to exclude the possibility of coincidence. If the embryo has stopped developing, but there are digestive symptoms due to gastrointestinal disorders, nausea and vomiting, it cannot be completely ruled out that the embryo has not stopped developing. It is best to check the embryo through ultrasound to see if the embryo is normal. If the embryo is still normal, give regular checkups and strengthen the nutrition in the diet. If the vomiting is relatively serious, it is best to go to the hospital to give rehydration therapy, and if necessary, also need to correct electrolyte disorders.
