Some sensitive pregnant women experience nausea and vomiting throughout their pregnancy. Pregnant women need to eat less and more often, eat light, easily digestible food and try to eat as much as possible to avoid the symptoms of malnutrition during pregnancy. If a pregnant woman’s previous pregnancy reactions have disappeared and she suddenly develops nausea and vomiting again in late pregnancy, she needs to go to the hospital for a timely examination. Exclude pregnancy complications, such as pregnancy with weakness, jaundice or nausea, vomiting and loss of appetite, and promptly check liver function to exclude liver disease in pregnancy and bile stasis syndrome. If nausea and vomiting accompanied by abdominal pain and diarrhea are symptoms of indigestion due to overeating or unclean diet, you can take oral probiotics for symptomatic treatment.
