If you experience heartburn or acid rising into your throat two or more times per week, and it’s been going on for several weeks, there’s a strong chance you’re dealing with GERD (gastroesophageal reflux disease) rather than ordinary heartburn. Everyone gets occasional acid reflux, but GERD is the chronic version, where stomach acid repeatedly flows back into your esophagus and irritates its lining over time.
Occasional Heartburn vs. GERD
Heartburn after a large meal or a glass of wine is common and usually nothing to worry about. It becomes GERD when the pattern is persistent: frequent episodes happening multiple times a week, lasting for weeks or months. The distinction matters because occasional reflux is a nuisance, while chronic reflux can gradually damage the tissue lining your esophagus.
A useful self-check comes from a scoring tool called the GerdQ, developed for primary care settings. It asks about six symptoms over the past week, each scored on frequency. A total score of 8 or higher corresponds to roughly an 80 percent likelihood of GERD, while scores of 3 to 7 put the probability around 50 percent. You can’t diagnose yourself with a questionnaire, but if your score lands in that higher range, it’s a strong signal to follow up with a doctor.
The Classic Symptoms
The two hallmark symptoms are heartburn and regurgitation. Heartburn feels like a burning sensation behind your breastbone that often worsens after eating, when lying down, or when bending over. Regurgitation is the sensation of acid or partially digested food rising into your throat or mouth, sometimes leaving a sour or bitter taste.
These tend to be worse at night. Many people with GERD find that lying flat allows acid to travel more easily up the esophagus, disrupting sleep and causing a sore throat by morning. If you regularly wake up with a bitter taste in your mouth or a burning feeling in your chest, that pattern alone is a significant clue.
Symptoms You Might Not Connect to GERD
GERD doesn’t always announce itself with obvious heartburn. Some people have what doctors call extraesophageal symptoms, meaning the acid affects areas beyond the esophagus. A chronic cough that doesn’t respond to typical treatments is one of the most common. The cough tends to be dry and persistent, often worse at night or after meals, and it happens because acid irritates the throat or, in some cases, gets inhaled into the airways and triggers inflammation there.
Other less obvious signs include a hoarse voice (especially in the morning), a feeling of a lump in your throat, difficulty swallowing, and worsening asthma symptoms. Some people notice dental erosion over time, since stomach acid is strong enough to wear down tooth enamel. If you have a lingering cough or hoarseness that no one can explain, GERD is worth considering as the cause.
Chest Pain and GERD
GERD is actually the most common cause of chest pain that isn’t related to the heart. The burning or pressure can feel alarmingly similar to cardiac pain, which is why many people with GERD end up in emergency rooms convinced they’re having a heart attack. The key differences: GERD-related chest pain often worsens after eating, responds to antacids, and doesn’t get worse with physical exertion. Heart-related chest pain typically comes on with activity and may radiate to the arm or jaw. That said, any new or severe chest pain warrants a trip to the ER to rule out cardiac causes first.
What Raises Your Risk
Certain conditions make GERD significantly more likely. Obesity is one of the biggest factors, because extra abdominal weight increases pressure on the stomach and pushes acid upward. A hiatal hernia, where the upper part of the stomach slides up through the diaphragm into the chest, directly weakens the barrier that normally keeps acid in the stomach. Pregnancy raises risk for the same pressure-related reasons, and gastroparesis (a condition where the stomach empties unusually slowly) gives acid more opportunity to reflux.
Several common medications can also trigger or worsen GERD. Anti-inflammatory painkillers like ibuprofen, certain anti-anxiety medications, some antidepressants, calcium channel blockers used for blood pressure, and some asthma medications all relax the muscular valve between the stomach and esophagus or irritate the esophageal lining directly. If you started a new medication around the time your symptoms appeared, that connection is worth flagging to your doctor.
How Doctors Confirm the Diagnosis
In many cases, your doctor will start with a simple approach: prescribing a short course of acid-reducing medication and seeing if your symptoms improve. This “PPI trial” has a sensitivity of 78 to 92 percent for identifying GERD, meaning it correctly identifies the condition in the vast majority of people who have it. If your symptoms resolve or significantly improve within a few weeks on the medication, that response itself supports the diagnosis.
When the picture is less clear, or when symptoms don’t respond to medication, doctors turn to more specific tests. An upper endoscopy involves passing a thin, flexible camera through your mouth and into your esophagus to look for visible inflammation, damage, or other conditions that could mimic GERD. During the procedure, the doctor can take small tissue samples to examine under a microscope.
The most precise test is esophageal pH monitoring, which directly measures acid levels in your esophagus over 24 to 48 hours. This can be done with a thin tube passed through the nose or a small wireless capsule attached to the esophageal lining during an endoscopy. While you wear the monitor, you log your meals, sleep, and symptoms, and the doctor matches those entries against the acid measurements. This test is typically reserved for cases where the diagnosis remains uncertain or when a doctor needs to confirm whether treatment is working.
What Happens If GERD Goes Untreated
Chronic, unmanaged acid reflux can cause real damage over time. The repeated exposure to stomach acid can inflame and erode the esophageal lining, a condition called esophagitis, which makes swallowing painful. Over years, scar tissue can build up and narrow the esophagus, making it physically harder to swallow solid food.
The most talked-about complication is Barrett’s esophagus, where the cells lining the lower esophagus change in response to chronic acid exposure. Barrett’s is a risk factor for esophageal cancer, though the actual risk is much lower than many people fear. A large study published in the New England Journal of Medicine tracked over 11,000 patients with Barrett’s esophagus and found the annual risk of developing esophageal cancer was 0.12 percent, considerably lower than the 0.5 percent figure that had previously been assumed. That’s reassuring, but it’s still a reason to manage GERD rather than ignore it for years.
Red Flag Symptoms That Need Prompt Attention
Most GERD symptoms are uncomfortable but not dangerous. However, certain signs suggest something more serious may be happening. Difficulty swallowing that gets progressively worse, pain when swallowing, unexplained weight loss, vomiting blood or material that looks like coffee grounds, and black or tarry stools all warrant prompt medical evaluation. These don’t necessarily mean cancer or another severe diagnosis, but they do need to be investigated rather than managed with over-the-counter antacids.
If food feels like it’s getting stuck in your chest or throat on a regular basis, that’s also a signal to get an endoscopy. A blockage that makes it hard to breathe is a medical emergency.
