The reason for this is that it is often due to hormonal changes after pregnancy, increased early pregnancy reaction and pressure on the stomach, which can be treated according to the cause. 1. hormonal changes: when pregnant, the body secretes too much estrogen, which leads to excessive production of stomach acid, and then patients experience abdominal pain, bloating, nausea, vomiting and other discomfort. At this time, attention should be paid to adjust the diet, avoid eating cold, spicy and stimulating food, do not drink coffee, it is advisable to eat food rich in high quality protein and high vitamin. Patients with heavy conditions can be treated with mucous membrane protective drugs under the guidance of a doctor, choosing drugs that have no adverse effects on the growth and development of the fetus and taking them appropriately; 2. Aggravation of early pregnancy reaction: because of the patient’s previous history of stomach problems, pregnancy will aggravate the early pregnancy reaction, which in turn will lead to symptoms of severe stomach discomfort. It is recommended that pregnant women with stomach problems should eat lightly, eat less and more often, avoid intake of greasy and high-fat diet, and pay attention to keep a happy mood; if vomiting is serious and cannot eat, they should go to the hospital in time, and those who are severely dehydrated should be hospitalized for rehydration, antiemetic and other related treatments, and most patients’ symptoms can be effectively relieved; 3. The patient can feel serious discomfort in the stomach when the stomach attack occurs, and can apply drugs to promote stomach digestion that will not adversely affect the fetus under the guidance of the doctor. If the symptoms are serious and medication is necessary, it should be applied under the joint consultation of gastroenterology and obstetrics and gynecology doctors to avoid the abuse of drugs that may have adverse effects on the fetus and the pregnant woman.
