Bloating and nausea may be caused by gastric dyskinesia, indigestion, chronic gastritis, etc., and can be treated with complementary therapies and medications. 1. Insufficient gastric power: the digested food in the stomach can not be pushed downward normally, resulting in stagnation in the stomach and continuous fermentation and gas production, resulting in increased intragastric pressure and bloating and nausea. Medications can be used to treat the condition, such as taking domperidone, mosapride and other drugs to promote gastric motility; daily diet should be light and easy to digest, avoid overeating and avoid spicy and stimulating foods. 2. Indigestion: Food cannot be digested completely, resulting in food being delayed and pushed downward, remaining in the stomach for a longer period of time. The continuous fermentation and gas production of food increases the pressure in the stomach, resulting in bloating and nausea. Medications such as domperidone, mosapride and other gastric stimulants can be used. 3. Chronic gastritis: Chronic gastritis is characterized by poor digestion and inflammation, which makes food difficult to be digested and stays in the stomach for a long time, resulting in diarrhea, nausea and other symptoms. Bloating and nausea may also be caused by other reasons, it is recommended to consult a doctor in a timely manner, under the guidance of a doctor to clarify the cause of the disease, standardized treatment, do not take medication, so as not to delay the condition.
