In my practice, I hear “it’s just a little heartburn” almost daily.

And most of the time, it is. A late-night pizza, one too many cups of coffee—we’ve all been there. But my job is to worry about the times it isn’t.

Let me tell you about a case like Clara’s. By her 80s, she’d had a decades-long battle with gastroesophageal reflux disease, or GERD.

It’s an incredibly common condition where stomach acid flows back into the esophagus. She eventually gave up, ignoring her doctor’s advice and eating whatever she wanted.

When she developed trouble swallowing, she dismissed it as just another symptom. It wasn’t. It was esophageal cancer, the sixth leading cause of cancer deaths worldwide.

Now, before you panic, a Harvard expert emphasizes that most GERD cases do not lead to cancer. But Clara’s story is a powerful reminder that persistent symptoms should never be ignored.

My goal isn’t to scare you; it’s to empower you. Let’s talk about why that nagging burn is a gamble you don’t want to take and what it might be telling you.

The Lineup: 5 Imposters That Feel Like GERD

When a patient comes to me with symptoms like heartburn, a metallic taste, hoarseness, or a chronic cough, my brain starts running through a list of possibilities.

We call this a “differential diagnosis.” Here are a few common GERD look-alikes that need to be on the radar.

• Hiatal Hernia: This is a mechanical issue where the top part of your stomach pushes up through the diaphragm, the muscle separating your abdomen and chest.
• As Dr. Elena Fradkov, a gastroenterologist at a Harvard-affiliated hospital, puts it, the stomach can look like “a tube of toothpaste squeezed in the middle”.
• This structural change can either cause GERD or exist alongside it.
• Functional Dyspepsia: This is the mystery guest.
• You have ongoing stomach pain or indigestion that feels just like GERD, but there’s no evidence of actual acid reflux into the esophagus.
• It’s frustrating for patients, but it’s a real and recognized condition.
• Eosinophilic Esophagitis: Think of this as an allergic reaction in your esophagus.
• A type of white blood cell called an eosinophil builds up in the esophageal lining, causing inflammation.
• While it can cause heartburn, the big clue here is often more significant trouble swallowing, or the feeling of food getting stuck.
• Esophageal Spasms: Just like you can get a charley horse in your leg, the muscles of your esophagus can have involuntary contractions.
• These can be triggered by certain medications or by eating very hot or cold foods, causing pain and difficulty swallowing.
• The One We Don’t Mess With: A Heart Attack: This is where I get serious. A heart attack can sometimes cause a burning sensation that mimics heartburn.
• But if that feeling is accompanied by sweating, shortness of breath, or pain that radiates to your back, you need to get to a hospital immediately.
• Don’t be a hero—let us figure it out.

Your Action Plan for Taming the Burn

To stop guessing, we often need to take a look inside.

A common and very helpful test is an endoscopy, which uses a thin tube with a camera to give us a direct view of your esophageal lining. This helps confirm GERD or rule out other causes.

If the culprit is, in fact, GERD, medication can help. But lifestyle changes are your first and best line of defense. Dr. Fradkov notes that for many, these adjustments can ease most, if not all, symptoms.

• Know Your Triggers: Common offenders include alcohol, coffee, chocolate, tomato sauce, citrus, and greasy or fried foods.
• Keep a food diary. Your body will give you clues if you listen.
• Rethink Your Mealtime Habits: Instead of three large meals, try five or six smaller ones throughout the day.
• Chew slowly. And give gravity a helping hand—stay upright for two to three hours after eating to keep stomach contents down.
• Manage Your Midsection: As Dr. Fradkov says, it’s “simple mechanics”.
• Extra belly fat puts pressure on the valve between the stomach and esophagus, squeezing contents upward.

Your Health Isn’t a Guessing Game

Look, the odds are your heartburn is just heartburn. But “probably” isn’t good enough when it comes to your health. Don’t brush off symptoms that won’t go away.

Talk to your doctor. It’s our job to connect the dots and rule out the scary stuff so you can get the right treatment and get back to your life.

Stop guessing, and let’s get you some real answers.
