Infant Reflux: Causes, Symptoms, Diagnosis and Treatment
Jan 18, 2024

Infant reflux is the term for a baby's spit-up. It happens when the stomach contents of a newborn reflux back up into the esophagus. The esophagus is the name of the muscular tube that connects the mouth and stomach.
Reflux happens regularly throughout the day in healthy babies. When a baby is growing and doing well, reflux is not a cause for concern. Older infants are less likely to experience the condition, sometimes referred to as gastroesophageal reflux disease, or GER. After the age of 18 months, reflux is uncommon in infants.
Rarely is infant reflux the cause of weight loss or growth that is slower than that of other children of the same age and gender. These indicators can indicate a medical problem. These medical conditions might be an allergy, a blockage in the digestive system, or gastroesophageal reflux disease (GERD). GERD is a more severe form of GER that can cause serious health issues.
Causes Of Infant Reflux
In neonates, the ring of muscle that joins the stomach to the esophagus is still growing. This muscle is known as the lower esophageal sphincter (LES). When it is not fully developed, the LES allows stomach contents to reflux up into the esophagus. Typically, the LES ages over time. It opens when your infant swallows and closes tightly the rest of the time to keep the stomach's contents in their right position.
Some causes of reflux in infants are common and oftentimes cannot be avoided. These include reclining down most of the time and being fed a diet that is virtually exclusively liquid.
Sometimes, more serious conditions like the ones listed below can be the reason for reflux in newborns:
- GERD: Acid reflux causes enough irritation and damage to the lining of the stomach.
- Stomach Stenosis: Food may go from the stomach into the small intestine via a muscular valve during the digestion process. When pyloric stenosis occurs, the valve thickens and enlarges more than it should. The thicker valve then keeps food in the stomach and keeps it from entering the small intestine.
- Dietary intolerance: One of the most common causes is a protein in cow's milk.
- Eosinophilic esophagitis: An aggregation of a certain kind of white blood cell damages the lining of the esophagus. This kind of white blood cell is called an eosinophil.
- Sandifer syndrome: As a result, there is unusual head rotation and tilting as well as seizure-like movements. It is an uncommon GERD side effect.

Symptoms Of Infant Reflux
Generally speaking, reflux in infants is not a reason for alarm. It is uncommon for stomach contents to contain enough acid to induce symptoms such as irritation of the esophagus or throat.
Diagnosis Of Infant Reflux
The doctor treating your child will first perform a physical examination and ask you about the symptoms your child is experiencing. Testing normally isn't necessary if your kid is healthy, growing as predicted, and appears content. However, in certain circumstances, your healthcare physician may advise:
- Ultrasound: Pyloric stenosis can be identified by this imaging examination.
- Experiments in the lab: Tests on the blood and urine can be used to determine or rule out potential reasons for low weight growth and recurrent vomiting.
- PH monitoring in the esophagus: The doctor will put a tiny tube through your baby's mouth or nose and into their esophagus to measure the acidity of their esophagus. The tube is fastened to an acidity monitoring apparatus. It may be necessary for your infant to remain in the hospital for observation.
- Radiography: These images can detect problems with the digestive system, such as obstructions. Your baby may be given a contrast liquid in a bottle before the test. This liquid is frequently barium.
- Upper endoscopy: The doctor uses a special tube that has a camera lens and light attached to it to reach your baby's mouth and the esophagus, stomach, and upper region of the small intestine. This tube is known as an endoscopy. Tissue samples can be acquired for analysis. For children and neonates, endoscopy treatments usually require general anesthesia. A sleeping-like state is induced before surgery or other medical operations using a combination of medicines called general anesthesia.

Treatment Of Infant Reflux
Most babies' reflux can be managed with simple feeding changes until the reflux resolves on its own.
Medications
Reflux medications are typically not used to treat mild reflux in children. The doctor treating your child, however, might suggest using an acid-blocking medication for a few weeks or months. Acid-blocking medications include cimetidine (Tagamet HB), omeprazole magnesium (Prilosec), and famotidine (Pepcid AC). Your child's physician may recommend an acid-blocking medication if your baby:
- Has not gained much weight, and feeding adjustments have not been successful Refuses to feed
- Has an esophageal inflammation
- Possesses a persistent asthma
Surgery
Your baby may rarely need surgery. This is only carried out if your child is not gaining enough weight or is having respiratory problems connected to reflux. During the surgery, the LES, which connects the stomach to the esophagus, is tightened. This prevents acid from flowing back up into the esophagus.
