The two hallmark signs of GERD are heartburn and regurgitation that keep coming back, typically two or more times a week. Heartburn feels like a burning sensation behind your breastbone that rises toward your throat, while regurgitation is the taste of food or stomach acid creeping back into your mouth. If either of these happens regularly rather than once in a while after a big meal, you’re likely dealing with GERD rather than occasional acid reflux.
Classic Symptoms and When They Happen
GERD symptoms follow a predictable pattern. The burning chest pain usually starts after eating, and it gets worse when you lie down or bend over. Many people notice it disrupts sleep, especially if they’ve eaten within two hours of going to bed. Antacids bring temporary relief, which is itself a clue: if an antacid makes your chest pain better, the pain is almost certainly acid-related.
Regurgitation often comes with a sour or bitter taste and a sensation of liquid moving up through your chest. Some people describe it as a “wet burp.” It tends to be worse after large meals, fatty or spicy foods, alcohol, or coffee. Lying flat or bending at the waist can push stomach contents upward and trigger an episode.
Symptoms You Might Not Connect to Reflux
GERD doesn’t always announce itself with heartburn. When stomach acid travels past the esophagus and reaches the throat or airway, it causes a related condition called laryngopharyngeal reflux, or “silent reflux.” Your throat tissues lack the protective lining your esophagus has, and they can’t wash acid away as efficiently, so even a small amount of reflux does outsized damage up there.
Symptoms of silent reflux include:
- Chronic cough that doesn’t respond to typical treatments
- Hoarseness or a lowered voice, especially in the morning
- A lump-in-the-throat feeling that won’t go away
- Constant throat clearing or excessive mucus
- Chronic sore throat or frequent laryngitis
- Worsening asthma or new wheezing
- Postnasal drip that doesn’t improve with allergy treatment
If you’ve been chasing these symptoms with allergy medications, cough suppressants, or antibiotics and nothing sticks, reflux may be the underlying cause. Many people with silent reflux never experience heartburn at all, which makes it easy to miss.
How to Tell It Apart From a Heart Problem
Heartburn and heart attacks can feel remarkably similar. Even experienced doctors can’t always distinguish them based on symptoms alone. That said, there are patterns worth knowing.
Heartburn typically burns, occurs after eating or while lying down, and improves with antacids. A heart attack more often feels like pressure, tightness, or squeezing in the chest, sometimes spreading to the neck, jaw, or arms. Heart attacks also tend to come with shortness of breath, cold sweats, lightheadedness, or sudden fatigue. Women are more likely than men to experience jaw pain, back pain, nausea, or shortness of breath as their primary heart attack symptoms rather than classic chest pain.
If your chest pain comes on during physical activity like climbing stairs, or if it’s accompanied by sweating, dizziness, or a feeling of dread, treat it as a cardiac emergency.
A Simple Self-Check
Gastroenterologists use a validated six-question screening tool called the GERD-Q to estimate the likelihood of a GERD diagnosis. You can run through the logic yourself by thinking about the past week and answering honestly:
- How many days did you have heartburn?
- How many days did you have regurgitation?
- How many days did reflux symptoms disturb your sleep?
- How many days did you take an over-the-counter antacid or acid reducer?
- How many days did you have nausea? (This one counts against a GERD diagnosis.)
- How many days did you have upper-belly pain? (This also counts against it.)
Each question is scored from 0 to 3 based on frequency. More heartburn, regurgitation, sleep disruption, and antacid use push the score higher. More nausea and stomach pain push it lower, because those symptoms suggest something other than reflux. On the 0-to-18 scale, scoring above 8 correlates with esophageal damage or abnormal acid levels in over 50% of cases. It’s not a diagnosis on its own, but it’s a useful way to gauge whether your symptoms add up to something worth investigating.
How Doctors Confirm a Diagnosis
Most people start with what’s sometimes called a “PPI trial,” where you take an acid-suppressing medication for several weeks. If your symptoms improve significantly, that response itself supports a GERD diagnosis. Many people never need testing beyond this.
When symptoms persist, don’t respond to medication, or raise concern about complications, doctors turn to two key tests. An upper endoscopy uses a thin, flexible camera threaded down your throat to look directly at the esophageal lining for signs of irritation, damage, or other problems. Ambulatory pH monitoring involves placing a small sensor near the base of your esophagus (sometimes clipped in place during an endoscopy) that records acid levels continuously for 24 to 96 hours. This test tracks exactly how often acid washes up and whether those episodes line up with your symptoms.
Between 50% and 90% of people with GERD also have a hiatal hernia, where part of the stomach pushes up through the diaphragm. A hiatal hernia doesn’t directly cause GERD, but it slows the process of clearing acid out of the esophagus, making symptoms more frequent and more severe. Doctors often discover one during endoscopy.
Warning Signs That Need Prompt Attention
Most GERD is uncomfortable but manageable. Certain symptoms, however, signal complications that need evaluation quickly:
- Trouble swallowing or a feeling that food gets stuck in your chest
- Choking while eating
- Unintentional weight loss
- Vomiting blood or material that looks like coffee grounds
- Black or red stools
- Chest pain during physical activity
Difficulty swallowing is particularly important because it can indicate narrowing of the esophagus from chronic acid damage. Bloody vomit or dark stools suggest bleeding somewhere in the upper digestive tract. These aren’t wait-and-see situations.
