Pregnancy nausea at night may be caused by hormone secretion, reflux esophagitis, hypoglycemia and other factors.
1. Hormone secretion: the large secretion of estrogen and human chorionic gonadotropin after pregnancy makes the intestinal peristalsis function decrease, which leads to indigestion of pregnant women and then the symptoms of vomiting and nausea at night.
2. Reflux esophagitis: when pregnant women with increased intra-abdominal pressure, gastric contents are subjected to pressure flow into the pharynx or mouth, resulting in pregnant women wanting to vomit at night nausea symptoms.
3. Hypoglycemia: hypoglycemia is caused by insufficient intake of nutrients during pregnancy. Hypoglycemia causes sympathetic nerve excitation and neurological dysfunction, which can make pregnant women feel nauseous at night.
If you are pregnant and have symptoms of nausea at night, it is recommended that you go to a professional hospital in time and actively cooperate with the doctor for treatment.
