Reflux in Infants
Gastroesophageal Reflux in Infants
Gastroesophageal reflux (GER) in infants occurs when stomach contents flow back into the esophagus. This usually happens due to dysfunction of the lower esophageal sphincter (LES), the muscular valve between the esophagus and the stomach.
This valve opens to allow food to pass into the stomach and then closes to prevent stomach contents from flowing back. When the valve does not function properly, stomach contents can return to the esophagus and cause symptoms such as heartburn, nausea, and discomfort. In severe cases, this condition may lead to inflammation and damage to the esophageal lining.
Reflux is common in infants and often occurs because of the small stomach capacity, relatively high milk intake, and slower gastric emptying. Almost all premature infants and many healthy infants experience some degree of reflux, which usually improves as the baby grows and the digestive system matures.
This condition often occurs after feeding, but it may also happen during crying, coughing, or straining.
Symptoms of Reflux in Infants
Symptoms can range from mild to severe and may include:
Poor weight gain or growth delay

Poor weight gain or growth delay
Severe or projectile vomiting
Vomiting with enough force that stomach contents are expelled forcefully from the mouth (projectile vomiting).
Feeding refusal or poor appetite Reluctance or refusal to feed.
Feeding refusal or poor appetite
Reluctance or refusal to feed.
Irritability and persistent crying Restlessness and continuous crying, especially after feeding.
Irritability and persistent crying
Restlessness and continuous crying, especially after feeding.
Blood in the stool Presence of blood in the infant’s stool.
Blood in the stool
Presence of blood in the infant’s stool.
If these symptoms persist, consultation with a physician is recommended.
Factors Contributing to Infant Reflux
Infant reflux is usually related to a combination of the following factors:
- Immaturity of the valve between the esophagus and stomach
- Lying flat on the back immediately after feeding
- A completely liquid diet
- Swallowing excess air during feeding
- Rapid or excessive milk intake in a single feeding
-
These factors can increase intragastric pressure and facilitate the backflow of stomach contents into the esophagus.
Rare Causes of Severe Reflux
In some cases, severe reflux may be caused by underlying conditions such as:
Cow’s milk protein allergy and allergic inflammation of the gastrointestinal tract
Advanced gastroesophageal reflux disease (GERD)
Narrowing or obstruction of the gastrointestinal tract
In such situations, specialist evaluation and targeted treatment are necessary.
Home Care and Supportive Measures to Reduce Reflux
In many infants, symptoms can be improved by following these recommendations:
Proper Feeding Position
- Feed the infant in a semi‑upright position.
- Keep the baby upright for up to 30 minutes after feeding.
- Avoid shaking or vigorous movement immediately after feeding.
Adjusting Feeding Schedule
- Increase the number of feedings while reducing the volume per feeding.
- If breastfeeding, consider shorter but more frequent feeds.
Regular Burping
- Burp the baby several times during and after feeding.
- Hold the baby upright and avoid pressure on the abdomen.
These measures can help reduce reflux-related complications in infants.

Additional Recommendations Formula Change
Changing infant formula may be recommended for formulafed infants, under the guidance of a physician or nutrition specialist. In many cases, symptoms may be related to cow’s milk protein sensitivity.
Maternal Diet Adjustment
If the infant is breastfed, modifying the mother’s diet may help reduce symptoms.
Reducing Feeding Volume
Reduce the amount of milk per feeding while increasing feeding frequency.
