Newborn flatulence is categorized into physiological flatulence, which is commonly caused by cold abdomen, inhaling too much air during breastfeeding, etc. Pathological flatulence, such as enterocolitis, is not excluded, which mainly manifests itself as farting, crying, not sleeping soundly and vomiting. 1. Physiological flatulence: when the newborn sucks milk too quickly or the size of the nipple hole of the bottle is not suitable, leading to inhalation of too much air, the newborn’s stomach will make a gurgling sound and fart a lot, and at the same time, it will cry and cry, but there is no obvious phenomenon of vomiting, and the spirit is good, and it is usually relieved after farting or defecation. 2. Pathological flatulence: The gastrointestinal function of newborn babies is not yet well developed, so they are prone to enteritis, intestinal obstruction and other diseases, which can be manifested as refusal to eat, sometimes frequent vomiting, crying, weight loss and other conditions, and even blood stools, tarry stools, fever and other symptoms. If a newborn baby has the above symptoms, and the symptoms are not relieved or accompanied by other discomforts, it is recommended to go to the hospital in time to find out the cause of the disease and give corresponding treatment.
