You can eat soy sauce even if you have a lot of stomach acid. Soy sauce refers to a traditional Chinese liquid condiment brewed from beans, wheat and bran. Soy sauce has no significant irritating effect on the mucous membrane of the human stomach, and there is no gastritis caused by soy sauce. Soy sauce contains amino acids, amino acids are the product of protein decomposition, so you can eat soy sauce if you have a lot of stomach acid. Long-term overproduction of gastric acid can also lead to chronic gastritis, gastric ulcer, duodenal ulcer, reflux esophagitis, gastrinoma and other digestive tract diseases. In addition to this may also cause chest tightness, chest pain, chronic cough, pharyngitis, dysphagia and so on. Excessive stomach acid can be treated with omeprazole, whose main effect is to act on the hydroxypotassium ATPase of the wall cells of the stomach acid, which makes the activity of hydroxypotassium ATPase change, and then inhibits the secretion of stomach acid, thus reducing stomach acid. If the patient has excessive stomach acid, it is recommended to go to the hospital in time, after clear examination, actively cooperate with the doctor for treatment.
