Infants spit up when they are held vertically, which may be caused by physiological factors such as imperfect development, small stomach capacity, changes in body position, or due to indigestion, gastroesophageal reflux and other diseases.
1. Physiological factors: Because the infant’s vomiting center is not yet well developed, the pharyngeal muscle group coordination ability is poor, so it is easy to spit up when you hold it vertically. It may also be caused by the small volume of the stomach and the relaxation of the sphincter at the lower end of the esophagus. Secondly, frequent changes in body position after breastfeeding, or change the amplitude is too large, to a certain extent, will also appear in the case of babies spit up when held vertically.

Dyspepsia: the causes of this disease include incomplete development of the digestive glands, neurological dysfunction, gastrointestinal dysfunction, Helicobacter pylori infection, etc. It can be triggered by overfeeding, improper feeding methods and other factors, resulting in abdominal distension, nausea, vomiting and other symptoms, which can sometimes be manifested as spitting up when held vertically.
3. Gastroesophageal reflux: this disease may be related to the anti-reflux function and structural damage, the esophagus to reduce the role of clearance, esophageal mucosal resistance to reduce the ability of other reasons, the typical symptoms of heartburn, reflux, nausea, belching (burp), etc., and some of the children will appear to be spit up when holding the phenomenon.
