If the stomach is bloated and gases come up but there is no problem in the examination, we can generally rule out pathological diseases, and the symptoms may be caused by excessive mental stress, indigestion or insufficient gastric power. 1. Excessive mental stress: Gastrointestinal health is closely related to the nervous and mental state. If you are under too much mental stress in a short period of time or in a state of prolonged mental tension, it may stimulate the gastric tissues and cause symptoms such as flatulence and acid reflux, which is a normal physiological phenomenon. 2. Indigestion: When eating too much in a short period of time causes accumulation of food or triggers indigestion, it will lead to the phenomenon of gastric flatulence. Appropriate abdominal massage or light walking can effectively promote digestion, thereby alleviating the discomfort. 3. Insufficient gastric power: in the absence of gastrointestinal pathology, insufficient gastric power is a common cause of flatulence, which may be triggered by too little daily activity or weak gastrointestinal function, and can be improved by proper massage of the abdomen or oral domperidone tablets and other gastric power drugs. When there is gastric flatulence and upwelling, you need to regulate your diet and have regular gastrointestinal examinations. In the choice of drugs to regulate, need to follow the doctor’s advice to use drugs carefully, not to self-medication.
