Newborn tummy grumbling may be related to gastrointestinal infection, gastrointestinal dysfunction, lactose intolerance and other reasons. 1. Gastrointestinal infections: If a newborn’s gastrointestinal tract is attacked by bacteria and other pathogens, intestinal peristalsis may increase, resulting in a grumbling sound. 2. Gastrointestinal dysfunction: gastrointestinal dysfunction can be caused by a cold abdomen, which may result in the sound of a grumbling stomach. 3. Lactose intolerance: If a newborn is unable to absorb lactose from breast milk or formula, it can cause abdominal pain, diarrhea, and other symptoms, which can lead to gurgling. Parents are advised to consult a doctor in time to clarify the cause of the disease, and if treatment is needed, standardized treatment should be carried out under the guidance of the doctor to avoid delaying the condition.
