Pregnant women who vomit and have diarrhea should also pay attention to the possibility of abdominal pain. Vomiting and diarrhea are most commonly associated with acute gastroenteritis, but pregnant women are a special group of people who must be more careful with their medication and choose drugs that have very little effect on the fetus. If you have vomiting and diarrhea, you can recommend the use of montelukast to stop diarrhea and reduce the discharge of stool. You can use Pantolac to reduce the secretion of gastric acid and repair the mucous membrane of the stomach so as to stop vomiting. If the blood test indicates elevated white blood cells and fever, antibiotics are recommended, and cephalosporin is the antibiotic of choice for pregnant women.
