Pregnant women who have difficulty in eating or not eating are generally considered to have early pregnancy reactions and need to choose dietary adjustments and rehydration therapy to stop vomiting according to the severity of the reaction. 1. Adjust the diet: It is recommended that pregnant women eat fewer meals to avoid a large number of meals at once and increase the burden on the stomach, which can easily lead to vomiting aggravation, and before two meals, it is recommended to eat some fruit and snacks. 2. Rehydration therapy: vomiting easily causes electrolyte disorders, so you need to replenish fluids to maintain the body’s water-electrolyte balance, which can help reduce the early pregnancy reaction. 3. Antiemetic treatment: Vitamin B6, for example, can effectively relieve nausea and vomiting symptoms, and can promote gastrointestinal peristalsis. In severe cases, strong antiemetic drugs can be taken, such as metoclopramide and ondansetron. In addition, the use of the above medications carries certain risks, and the patient needs to be guided by a specialist.
