If the mother has mild vomiting and diarrhea, she should take rest, drink more water, avoid eating greasy, spicy and irritating food, eat a light diet and eat easily digestible food, and her symptoms will be relieved in a week. If the mother has severe vomiting, diarrhea, abdominal pain and fever, she needs to seek medical attention and inform the doctor that she is currently breastfeeding. The doctor will give symptomatic treatment according to the patient’s clinical manifestations, and generally recommends taking probiotics, montelukast, omeprazole and other drugs that protect the gastrointestinal tract to relieve symptoms. In order to avoid the effect of drugs on young children through breast milk, breast milk should be suspended. During the suspension of breast milk, breast milk should be sucked regularly to avoid blockage and the breast pump should be disinfected. Gastroenteritis during breastfeeding is usually an acute inflammation caused by the consumption of unclean or cold food that stimulates the gastrointestinal mucosa, manifested as vomiting, nausea, diarrhea, abdominal pain with fever, dehydration, electrolyte disorders and other symptoms.
