Introduction
Most people associate a cough after eating only with acid reflux — but not all reflux causes heartburn. When stomach contents travel upward without classic burning sensations, it’s called silent reflux or laryngopharyngeal reflux (LPR). Understanding how silent reflux differs from GERD can help readers who cough after meals but never feel heartburn.
What Is GERD? (Acid Reflux Cough)
GERD (gastroesophageal reflux disease) occurs when the lower esophageal sphincter doesn’t close properly, allowing stomach acid to travel back up the food pipe. This acid can irritate the esophagus and trigger a cough after eating. Heartburn, sour taste, or chest discomfort often accompany GERD.
Common GERD signs:
- Heartburn
- Regurgitation
- Sour taste in mouth
- Coughing after meals
What Is Silent Reflux (LPR)?
Silent reflux involves stomach contents rising higher — all the way to the throat or voice box — without typical heartburn. Because the throat is more sensitive, even a small amount of irritation can trigger symptoms without warning.
Silent reflux triggers coughing by:
- Irritating throat tissue
- Activating cough reflex receptors
- Causing throat clearing and hoarseness
Silent Reflux vs GERD: Key Differences
| Feature | GERD | Silent Reflux (LPR) |
| Heartburn | Common | Rare |
| Regurgitation | Common | Often none |
| Cough After Eating | Possible | Very common |
| Hoarseness | Less | More |
| Throat Clearing | Less | More |
Silent reflux may only show up as a cough after eating, especially after large meals or trigger foods.
Typical Silent Reflux Symptoms
Even without heartburn, silent reflux commonly causes:
- Chronic dry cough after meals
- Frequent throat clearing
- Hoarse or raspy voice
- Sensation of something stuck in throat
Causes & Common Triggers
Silent reflux can be triggered by similar factors as GERD:
- Spicy or fatty foods
- Coffee and acidic drinks
- Eating late at night
- Large meals
- Smoking or alcohol
Avoiding triggers and adjusting habits can reduce cough frequency.
Simple Strategies That May Help
- Eat smaller meals
- Don’t lie down right after eating
- Keep a food and symptom diary
- Sip water during meals
- Avoid trigger foods
These lifestyle adjustments sometimes reduce coughing even without medication.
When to Seek Medical Advice
Consult a health professional if:
- The cough persists for weeks
- You notice associated symptoms like weight loss
- You have difficulty swallowing
- Cough disrupts sleep or daily life
A clinician can evaluate silent reflux or other causes that aren’t obvious at first.
