In early pregnancy, the vast majority of people will experience early pregnancy reactions such as nausea, vomiting, anorexia, decreased appetite, etc. and will not be able to eat. However, in order to meet the needs of embryonic development, it is important to maintain a balanced diet with fewer and more frequent meals, more fresh vegetables and fruits, and a light diet. You can always carry small snacks in your pocket, such as sour plums that can promote digestion and improve appetite. If you vomit so much that you really can’t eat and there is an electrolyte disorder, you must have intravenous supplementation or even be hospitalized. This is a serious matter because prolonged starvation can produce ketone bodies, which can affect the development of the fetal nervous system.
