The newborn spits up milk right after feeding.
Spitting up milk after feeding in newborns may be caused by factors such as excessive milk intake, allergies, indigestion, gastrointestinal dysfunction, or gastroesophageal reflux. It is recommended to treat based on the underlying cause.
1. Excessive Milk Intake
When a newborn drinks too much milk at once or feeds too quickly, the digestive system may become overloaded. The excess milk cannot properly enter the stomach and may flow upward, resulting in spitting up. It is recommended to feed on demand, appropriately reduce the amount of milk per feeding, or adopt a strategy of smaller, more frequent feedings.
2. Allergy
Newborns may be exposed to allergens through breast milk from the mother or infant formula, such as cow's milk protein or soy protein. This can trigger an immune response leading to gastrointestinal discomfort and spitting up. It is advisable to visit a hospital for evaluation and testing to identify the specific allergen and avoid further exposure.
3. Indigestion
A newborn’s stomach is small and can only hold a limited amount of food. Overfeeding or rapid feeding may exceed gastric capacity, causing indigestion and allowing food to flow back into the esophagus or mouth, leading to spitting up. Avoid large feedings; instead, use a frequent, small-volume feeding approach to help relieve symptoms.
4. Gastrointestinal Dysfunction
A newborn’s gastrointestinal system requires time after birth to adapt and mature. When the digestive system is not yet fully developed and gastric emptying is weak, overfeeding can cause food to remain in the stomach longer, increasing the risk of spitting up. Adjusting feeding methods—such as increasing feeding frequency and shortening intervals between feedings—can help alleviate symptoms.
5. Gastroesophageal Reflux
In newborns, the lower esophageal sphincter may be underdeveloped or insufficiently strong, making it easier for stomach acid and contents to flow back into the esophagus, causing spitting up. Adjusting the baby’s position—such as elevating the head or feet—can help reduce reflux symptoms.
It is recommended to seek medical evaluation for accurate diagnosis through thorough examination and receive treatment under a doctor’s guidance to prevent delayed care and worsening of the condition. In daily care, pay attention to proper newborn care practices, including maintaining warmth and appropriate feeding.
