Pregnancy vomiting is not always vomiting. Some pregnant women will only show mild nausea during pregnancy, or will only show a loss of appetite and not significant vomiting. Some patients may experience vomiting, while others may experience vomiting so severe that they cannot hold food in their stomachs and may experience nausea and vomiting even if they drink water. If the condition is not serious, no medication is needed and it will not affect the body. If the nausea and vomiting is serious, it can be treated with vitamin B6 orally or with intravenous fluids to relieve the nausea and vomiting.
