GERD is diagnosed when acid reflux happens frequently, typically two or more times per week, or when it has already caused damage to the lining of your esophagus. Everyone experiences occasional acid reflux after a heavy meal or a late night snack. The difference between normal reflux and GERD is persistence: if that burning feeling behind your breastbone keeps showing up, you’re likely dealing with something more than a one-off episode.
The Core Symptoms of GERD
The two hallmark symptoms are heartburn and regurgitation. Heartburn is a burning sensation in the chest that typically flares after eating and gets worse at night or when you lie down. Regurgitation is the backwash of sour liquid or partially digested food into your throat or mouth. Most people with GERD experience one or both of these regularly.
Beyond those two, GERD can cause upper belly or chest pain, difficulty swallowing, and a persistent feeling of a lump in your throat. If reflux is worse at night, you may also notice a chronic cough, hoarseness or laryngitis, and worsening asthma symptoms. These nighttime signs are easy to dismiss because they don’t feel like “stomach problems,” but they point to the same underlying issue: stomach acid repeatedly reaching places it shouldn’t.
GERD Without Heartburn
Some people have what’s called silent reflux, or laryngopharyngeal reflux (LPR). Acid travels past the esophagus and reaches the throat and voice box, but it doesn’t always trigger classic heartburn. Instead, the symptoms mimic other conditions: frequent throat clearing, a hoarse voice, a sticky feeling of mucus in the back of the throat, postnasal drip, or a cough that worsens after eating or lying down. You might also feel throat pain or have trouble swallowing without ever experiencing that typical chest burn.
Silent reflux is harder to pin down. No single throat finding is specific enough to confirm it on its own, and even an endoscopy can come back normal. Diagnosing it often requires specialized pH monitoring, where a small sensor tracks acid exposure in the upper esophagus and throat over 24 hours while you go about your normal routine. If you’ve been treated for allergies or sinus issues without improvement, silent reflux is worth considering.
A Simple Way to Track Your Symptoms
Doctors sometimes use a structured questionnaire called the GerdQ to help sort out whether symptoms add up to GERD. You can use the same logic at home by honestly tracking six things over a typical week:
- How many days did you feel a burning sensation behind your breastbone?
- How many days did stomach contents move up into your throat or mouth?
- How many days did you have pain in the center of your upper stomach?
- How many days did you feel nauseous?
- How many days did heartburn or regurgitation disturb your sleep?
- How many days did you need an over-the-counter antacid on top of any other medication?
The pattern matters more than any single answer. Frequent heartburn and regurgitation (several days a week), combined with sleep disruption and regular antacid use, strongly suggests GERD. Central stomach pain and nausea, on the other hand, point away from GERD and toward other conditions like gastritis or an ulcer. If you’re reaching for over-the-counter acid reducers more than twice a week, that alone is a signal worth acting on.
How to Tell It’s Not Your Heart
GERD chest pain and cardiac chest pain can feel disturbingly similar, which is why this distinction matters. Reflux-related chest pain tends to burn, often follows a meal, and may improve when you sit upright or take an antacid. Cardiac chest pain is more likely to come with sweating, shortness of breath, and a squeezing or pressure sensation that worsens with physical activity like climbing stairs.
If pressing on the sore spot on your chest wall reproduces or increases the pain, that’s another clue it’s musculoskeletal rather than cardiac. But chest pain with exertion, unexplained sweating, or shortness of breath should never be chalked up to reflux without ruling out a heart problem first.
Symptoms That Need Prompt Attention
Certain warning signs suggest GERD may have already caused complications, or that something else entirely is going on. These include choking while eating or progressive difficulty swallowing food and liquids, losing weight without trying, vomiting blood or material that looks like coffee grounds, and stools that are red or black. Any of these warrants a conversation with a healthcare provider sooner rather than later.
What Happens During a Medical Evaluation
For many people, GERD is diagnosed based on symptoms alone, especially if heartburn and regurgitation respond to a trial of acid-reducing medication. When symptoms don’t improve, or when warning signs are present, the next step is usually an upper endoscopy. During this procedure, a gastroenterologist passes a thin, flexible scope with a camera through your mouth and into the esophagus and stomach while you’re sedated. It takes about 15 to 20 minutes and lets the doctor check for inflammation, narrowing, and precancerous changes called Barrett’s esophagus that can develop after years of uncontrolled reflux.
If the endoscopy looks normal but symptoms persist, pH monitoring can measure exactly how much acid is reaching your esophagus over a 24- to 48-hour period. A small wireless capsule is attached to the esophageal lining during an endoscopy, then you go home and carry on with your regular diet and activities while the capsule records data. This test is particularly useful before anti-reflux surgery, or when there’s doubt about whether acid is truly the culprit.
GERD in Babies
Infants spit up constantly, and most of the time it’s normal gastroesophageal reflux that resolves within the first year. GERD in babies looks different from adult GERD because a baby can’t tell you their chest is burning. Instead, the signs are behavioral and physical: forceful vomiting, irritability or back-arching during feedings, refusing to nurse or take a bottle, poor weight gain, wheezing, noisy breathing, or hoarseness.
The challenge is that many of these symptoms overlap with other conditions, from milk protein intolerance to respiratory infections. No single symptom confirms infant GERD. A pattern of feeding difficulties combined with poor growth is what typically prompts further evaluation by a pediatrician or pediatric gastroenterologist.
Putting It All Together
If you experience heartburn or regurgitation two or more times a week, your symptoms get worse when you lie down or after meals, you regularly rely on antacids, and this pattern has persisted for several weeks, you’re looking at a picture consistent with GERD. The more of those boxes you check, the more likely the diagnosis. Silent reflux is trickier because the symptoms overlap with allergies and sinus problems, but a pattern of throat clearing, hoarseness, and cough that doesn’t respond to typical treatments is a strong clue. Tracking your symptoms for a week or two before a medical visit gives both you and your provider something concrete to work with.
