Hi there, that is true. Nausea
sensation is a part of gastritis
helps to decrease acid secretion. If you have motility problem in your digestive system. you can ask your doctor to give you a medication to treat increased movements in the stomach which can cause burping. You can also ask your doctor to send sample for H Pylori testing. If it is positive, treating for three weeks (more or less) with some antibiotics can help for long time improvement. I wish you a good health.
