The vast majority of pregnant women experience nausea and vomiting in the early morning, and this often improves in the evening. If you vomit a lot at night, it is mainly due to individual differences. It is recommended to eat less and more often, eat easily digestible food, especially 2 hours before going to bed, so as not to increase the burden on the gastrointestinal tract and cause the phenomenon of vomiting. In addition, if you can’t improve the symptoms of vomiting at night by improving your diet, you can take vitamin B6 orally to relieve the vomiting situation. If the vomiting is very serious and you eat very little clinically, it is recommended to go to the hospital for examination, mainly to rule out ionic disorders and acidosis, and if necessary, to give rehydration for treatment.
