The patient first develops stomach pain with dry heaving or vomiting, which has little to do with pregnancy. In this case, it is mainly considered that the patient may be caused by bad food or gastric diseases such as inflammation or ulcerative diseases of the stomach. Of course, this situation does not exclude the patient after pregnancy combined with stomach diseases. If a woman is only nauseated and vomiting after pregnancy, it will not be accompanied by pain and discomfort in the stomach, unless the patient vomits heavily, causing damage to the gastric mucous membrane, which may cause pain in the stomach. In the beginning, stomach discomfort caused by pregnancy mainly manifests as dry heaving and nausea, especially when smelling irritating odors, which is more serious, and is more serious in the morning, and is usually not accompanied by stomach pain.
