Vomiting, no fever, and no diarrhea in babies are caused by food accumulation, indigestion, and gastrointestinal dysfunction. The function of the baby’s digestive system is not particularly strong and the inability to empty the food in time when too much food is consumed can lead to the appearance of pent-up food. The accumulation of food can lead to abnormal fermentation of food in the stomach, producing a large amount of gas, resulting in increased pressure in the stomach and therefore accompanied by vomiting symptoms. Since pneumatosis is not related to bacterial infection, fever and diarrhea do not occur. Some babies will be accompanied by indigestion, food digestion time will be relatively longer, too much food intake can not be emptied in time, will cause the symptoms of vomiting. Some babies have eaten too cold or too stimulating food in their diet, which can cause stimulation of the gastric mucosa when the food enters the stomach, leading to stomach cramps and vomiting. When the symptoms appear, you can use the oral liquid and tablets to improve the stomach. At the same time, let the baby fast for a period of time to help the function of the digestive system to recover.
