Stomach discomfort and vomiting are usually associated with gastrointestinal disorders, improper diet, gastritis, gastric ulcer and other factors. First of all, the appearance of gastrointestinal dysfunction will lead to slow peristalsis, poor food digestion and other phenomena. Since food is not discharged in time, it will cause irritation to the stomach wall, which will not only cause stomach discomfort, but also lead to excessive expansion of the stomach body when food is poorly fermented, causing symptoms such as nausea and vomiting. Secondly, some people experience stomach discomfort and symptoms of nausea and vomiting because of dietary factors, such as the intake of food that is too cold, irritating, difficult to digest, or has become corrupt or spoiled, which will not only cause the performance of stomach pain, but also cause symptoms of nausea and vomiting due to toxic substances that cause irritation to the intestines and stomach. In addition, there are some people who suffer from stomach diseases, such as gastritis and gastric ulcer. These diseases not only cause pain in the stomach, but also affect the peristaltic function of the stomach, resulting in nausea and vomiting.
