11 Warning Signs of Acid Reflux You Shouldn’t Ignore
You should consider a gastroscopy (gastroscopie) if your reflux doesn’t go away with medication or if you have red flag symptoms like difficulty swallowing, persistent chest pain, or unexplained weight loss. While occasional heartburn is normal, these signs suggest your reflux might be damaging your esophagus. A quick endoscopy (endoscopie) is the only way to get a clear diagnosis and prevent long-term issues.
Key Takeaways
- If you’re using antacids more than twice a week, it’s time for a professional check-up.
- Symptoms like hoarseness or a “lump in the throat” are often “silent” signs of acid damage.
- In 2026, private clinics in Montreal can provide a gastroscopy in days, bypassing month-long public wait times.
- An endoscopy allows doctors to see exactly what’s happening inside, from inflammation to early-stage risks.
Whether it’s a late-night smoked meat sandwich in the Plateau or a heavy poutine after a Canadiens game, Montreal is a city that loves to eat. But for many of us, that love comes with a price: a burning chest, a sour taste, or a cough that just won’t quit.
It’s easy to dismiss these as “just part of getting older” or a reaction to spicy food. But there is a point where your body stops asking for a Tums and starts demanding a real answer. If you’ve been living on antacids or worrying about the “Quebec waitlist” for a specialist, this guide is for you.
What is the Difference Between Heartburn and Gerd?
Heartburn is a symptom; GERD (Gastroesophageal Reflux Disease) is the chronic condition. If your heartburn is frequent enough to cause tissue damage, a physician will use a gastro-endoscope to visually inspect the lining of your esophagus.
| Symptom Severity | Typical Experience | Recommended Action |
| Mild / Occasional | After spicy food or large meals. | Lifestyle changes / Occasional antacids. |
| Moderate / Frequent | 2+ times per week; disrupts sleep. | Consult a specialist; discuss PPIs. |
| Severe / Chronic | Constant pain; difficulty swallowing. | Urgent gastroscopie to check for damage. |

When Is It Time to Book a Gastroscopy?
A gastroscopy (gastroscopie), which is an upper endoscopy, becomes necessary when your symptoms become “refractory.” This is medical speak for “the medicine isn’t working anymore.” If you’re taking PPIs and still feeling the burn, we need to look at the source.
How Do I Know If My Reflux Is Serious?
It comes down to frequency and intensity. Chronic acid exposure can lead to “Barrett’s Esophagus,” a condition where the lining of your food pipe actually changes its cell structure. We use a gastro-endoscope to catch these changes before they become something worse.
| The Symptom | What it feels like | Why it’s a warning |
| Dysphagia | Food feels “stuck” in your chest. | Could be a stricture (narrowing) or a tumor. |
| Chronic Cough | A dry cough that gets worse at night. | Acid is irritating your lungs or throat. |
| Chest Pain | A crushing burn behind the ribs. | Easy to mistake for heart issues; needs a scope. |
| Regurgitation | Tasting bitter fluid in your sleep. | Your “valve” (LES) isn’t closing properly. |

What are the Tell-tale GI Signs You Shouldn’t Ignore?
Here are a few signs that indicate a serious GI issue.
1. Dysphagia
If you find yourself chewing extra-long or avoiding “tough” foods like steak or bread because they feel like they won’t go down, pay attention. This is often the first sign of a physical blockage or narrowing that only a gastroscopy (gastroscopie) can see.
2. Chest Pain That Isn’t Your Heart
We always say: check your heart first. But if the ER says your heart is fine and the pain persists, it’s likely acid. The burning can be so intense it mimics a cardiac event.
3. Persistent Cough Without a Cold
Many of our Montreal patients think they have “adult-onset asthma.” In reality, micro-droplets of stomach acid are being inhaled into the lungs, causing a constant, tickling cough.
4. Losing Weight Without Trying
Losing weight without a new gym routine or diet is rarely a good sign in digestive health. It often means your body is struggling to swallow or process nutrients correctly.
5. Waking Up With a Sour Taste
If you wake up with a “battery acid” taste or a sore throat every morning, you are refluxing in your sleep. This is high-volume reflux that can lead to “aspiration pneumonia” if you ignore it.
6. The “Gravelly” Voice
Acid vapors can literally “cook” your vocal cords over time. If your voice sounds hoarse for more than two weeks, a specialist needs to use an endoscopy (endoscopie) to check for damage to your larynx.
7. A Permanent “Lump” in Your Throat
This is called the “Globus” sensation. It feels like you swallowed a pill that didn’t go all the way down. It’s actually your throat muscles swelling in a protective response to acid.
8. Nausea That Lingers
Feeling slightly “green” all the time? Chronic nausea, especially in the morning, is a classic sign of stomach lining irritation (gastritis) or an underlying ulcer.
9. Your Dentist is Worried
Stomach acid is strong enough to melt dental enamel. If your dentist notices thinning on the back of your teeth, your reflux is reaching your mouth—usually while you sleep.
10. Bloating and Constant Burping
If you feel like a “balloon” after every meal and burp constantly, it’s a sign of pressure. This often points to an H. pylori infection or an issue with how your stomach empties.
11. Anemia or Dark Stools
This is the most urgent sign. If acid has caused a bleeding ulcer, you might feel exhausted (anemia) or notice very dark, tarry stools. This requires a gastroscopy (gastroscopie) immediately to stop the bleed.

Summary Recap
Acid reflux isn’t just a nuisance; it’s a message from your body. Signs like trouble swallowing, chronic hoarseness, and unexplained weight loss are “alarm symptoms” that shouldn’t be ignored. In 2026, a private endoscopy (endoscopie) in Montreal is the fastest way to stop the guesswork and start feeling like yourself again.
