If you notice that your baby is fussier than usual, arching their back, and often spitting up, it’s natural to worry about what’s causing these symptoms. One possible explanation is silent reflux, a condition that affects many babies. In this article, we’ll explore what silent reflux is, what causes it, and how you can address it.

What Is Silent Reflux?
Silent reflux, also known as laryngopharyngeal reflux (LPR), is a condition where stomach acid flows back into the throat and irritates the tissues there. Unlike gastroesophageal reflux disease (GERD), which causes heartburn and regurgitation, silent reflux is not always accompanied by these symptoms. Instead, babies with silent reflux may experience discomfort, feeding difficulties, and respiratory issues.
What Causes Silent Reflux in Babies?
There are several factors that can contribute to the development of silent reflux in babies. These include:
- An immature digestive system: In young babies, the muscle that separates the esophagus from the stomach (the lower esophageal sphincter) may not be fully developed yet, allowing stomach contents to flow back up more easily.
- An overactive let-down reflex: Sometimes, a mother’s milk may come out too fast, causing babies to swallow air and leading to reflux.
- An intolerance to certain foods: Some babies may be sensitive to certain foods in their mother’s diet, such as dairy or soy, which can cause reflux symptoms.
- An anatomical abnormality: In rare cases, babies may have an abnormality in their esophagus or digestive system that causes reflux.
What Are the Symptoms of Silent Reflux?
The symptoms of silent reflux can be difficult to recognize, as they may not always involve regurgitation or vomiting. However, here are some signs that your baby may be experiencing silent reflux:
- Arching their back during or after feeding
- Fussiness or crying during or after feeding
- Difficulty sleeping, waking up frequently, or refusing to sleep
- Spitting up frequently, sometimes with a gurgling sound
- Hoarseness or a chronic cough
- Difficulty breathing or wheezing
- Refusing to eat or taking only small amounts during feedings
How Is Silent Reflux Diagnosed?
If you suspect that your baby has silent reflux, it’s important to talk to your pediatrician. They may perform a physical exam and ask about your baby’s symptoms and feeding habits. In some cases, your doctor may refer you to a specialist who can perform further tests, such as a pH probe study or an upper GI endoscopy, to confirm the diagnosis.
How Can Silent Reflux Be Treated?
There are several strategies that can help manage the symptoms of silent reflux in babies. These include:
- Feeding modifications: For babies with an overactive let-down reflex, switching to a slower-flow nipple or breastfeeding position can help. Some babies may also benefit from smaller, more frequent feedings to avoid overloading the stomach.
- Medications: In some cases, your pediatrician may recommend medication to reduce stomach acid or improve the function of the lower esophageal sphincter. However, these medications are usually only used in severe cases.
- Dietary changes: If your baby is sensitive to certain foods, eliminating them from your diet if you are breastfeeding or switching to a hypoallergenic formula can help.
- Elevating the head of the bed: Placing a wedge under the head of the bed or using a special reflux pillow can help keep stomach contents from flowing back up into the throat.
If you’re concerned that your baby may be experiencing silent reflux, it’s important to seek medical attention. While the condition can be uncomfortable and disruptive, with the right treatment, most babies are able to overcome it and thrive.
