Shallow stomach belongs to the common name, which refers to the symptoms of nausea and vomiting easily after adverse stimuli, mostly belonging to physiological individual differences and more sensitive sense of smell or taste, which can be related to abnormal nerve function and nausea and vomiting symptoms after seeing bloody or malignant objects through vision. Nausea and vomiting symptoms due to these causes can be treated with repeated adverse stimuli to achieve physiological tolerance. There may also be pathological causes. If one has diseases such as hepatitis, cholecystitis or gastritis, nausea and vomiting symptoms may also occur upon smell of fumes or sight of fatty foods. Gastroscopy and liver function tests are needed to determine this. If it is due to gastritis, it can be treated with domperidone and lactase, and hepatitis can be treated with liver protection tablets, glycine and other drugs.
