Mid-pregnancy acid reflux spitting may be caused by pregnancy reaction, reflux esophagitis, gastritis and other diseases. 1. Pregnancy reaction: After pregnancy, due to the change of hormone levels in the body, it is easy to lead to changes in the gastrointestinal tract, causing acid reflux. A small number of pregnant women may experience this throughout their pregnancy. It is recommended to adjust the dietary structure of your life and increase the intake of alkaline food as appropriate. 2. Reflux esophagitis: If the sphincter of the lower esophagus cardia is dysfunctional, then it is also easy to cause acid reflux into the mouth. 3. Gastritis: If you have gastritis during pregnancy, such as superficial gastritis or erosive gastritis, then the destruction of the gastric mucosa will lead to excessive secretion of gastric acid, which will also cause acid reflux. Mid-pregnancy regurgitation and acid reflux is recommended to consult a doctor as soon as possible, under the guidance of a professional physician to identify the cause of the disease.
