Silent reflux in babies, unlike regular reflux, occurs when stomach contents enter the esophagus but don't come out of the baby's mouth. Instead, the contents return to the stomach, sometimes because the baby swallows them, or because they don't reach the mouth.
In essence, it's reflux without the spit-up.
Here's a breakdown:
Understanding the Difference: Reflux vs. Silent Reflux
| Feature | Reflux (GER) | Silent Reflux (Laryngopharyngeal Reflux - LPR) |
|---|---|---|
| Spit-up | Frequent and noticeable | Minimal or absent |
| Primary Symptom | Visible regurgitation | Irritability, feeding difficulties, respiratory issues |
| Mechanism | Stomach contents rise and exit the mouth | Stomach contents rise, but are swallowed again or don't reach the mouth. |
Why is it Called "Silent"?
The term "silent" refers to the lack of visible spitting up or vomiting. The reflux is happening, but you don't see the obvious signs.
Potential Symptoms of Silent Reflux
Since there's no spit-up, recognizing silent reflux can be challenging. Look out for these signs:
- Arching the back: Especially during or after feedings.
- Feeding refusal or difficulty: Baby may seem uncomfortable while eating.
- Irritability and fussiness: Particularly after feedings.
- Frequent hiccups or coughing: These can be triggered by the reflux.
- Hoarse voice or chronic cough: Reflux can irritate the vocal cords.
- Breathing problems: Such as wheezing or noisy breathing.
What to Do If You Suspect Silent Reflux
If you suspect your baby has silent reflux, it's important to consult with your pediatrician. They can properly diagnose the condition and recommend appropriate management strategies.
