What is Gastroesophageal Reflux (GER)?
Gastroesophageal reflux (GER) is a condition where the contents of the stomach flow back into the esophagus. This can happen due to an underdeveloped lower esophageal sphincter (LES), which is common in neonates. GER is prevalent in neonates, and it can cause a range of symptoms, from mild to severe.
How Common is GER in Neonates?
GER is quite common among neonates, affecting up to 50% of infants in the first three months of life. Most infants outgrow this condition by the age of 12 to 18 months as the LES matures.
Frequent regurgitation or vomiting
Irritability during or after feeding
Poor feeding or refusal to eat
Arching of the back during feedings
Respiratory issues like coughing or wheezing
Poor weight gain
What Causes GER in Neonates?
The primary cause of GER in neonates is the immaturity of the lower esophageal sphincter (LES). Other factors include:
Overfeeding
Shorter esophagus
Horizontal position most of the time
Prematurity
Neuromuscular disorders
How is GER Diagnosed in Neonates?
Diagnosis of GER in neonates is generally clinical, based on the symptoms presented. However, in severe cases or when complications are suspected, further diagnostic tests may be required:
Lifestyle and feeding changes - Smaller, more frequent feedings, keeping the baby upright after feeding
Medications - Antacids, H2 blockers, or proton pump inhibitors (PPIs) in severe cases
Surgery - In rare, severe cases, a procedure known as fundoplication may be performed
Can GER Lead to Complications?
While many neonates outgrow GER without any long-term issues, severe or untreated GER can lead to complications such as:
Frequent or forceful vomiting
Blood in vomit or stool
Poor feeding or refusal to eat
Chronic cough or breathing difficulties
Poor weight gain or weight loss
Conclusion
Gastroesophageal reflux is a common condition in neonates that usually resolves as the infant grows. Understanding the symptoms and seeking appropriate medical advice can help manage the condition effectively and prevent complications.
