Occasional heartburn is common. Frequent burning, a sour taste or a nagging cough may point to GERD. Here is what causes it, what helps and when to see a doctor.

Almost everyone knows the feeling: a burning that climbs up behind the breastbone after a big dinner, a spicy meal or one glass of wine too many. Once in a while, it is a nuisance. But when heartburn shows up week after week, wakes you at night or leaves a sour taste in your mouth most mornings, it may be more than a rich meal talking. It may be gastroesophageal reflux disease, better known as GERD, one of the most common digestive problems doctors see.
In brief
- Occasional heartburn is common; reflux that happens regularly, often twice a week or more, may be GERD.
- Simple habits like smaller dinners and not lying down right after eating help many people.
- Trouble swallowing, vomiting blood, black stools or weight loss you can’t explain need a doctor’s attention.
What is acid reflux, and when is it GERD?
At the bottom of your esophagus, the tube that carries food from your mouth to your stomach, sits a ring of muscle called the lower esophageal sphincter. Its job is simple: open to let food through, then close tightly so stomach contents stay put. When that valve relaxes at the wrong time or doesn’t seal well, stomach acid washes back up into the esophagus. That backward flow is acid reflux, and the burning it causes is heartburn.
Reflux on its own is not unusual. Most adults have it now and then. Doctors start thinking about GERD when reflux happens regularly, often defined as at least twice a week, or when it causes irritation, ongoing symptoms or complications. The difference matters, because frequent acid exposure over months and years can inflame and change the lining of the esophagus.
Common symptoms of GERD
Heartburn is the classic sign, but GERD doesn’t always announce itself that way. Symptoms can include:
- Heartburn: a burning feeling in the chest, often after eating and often worse when lying down or bending over.
- Regurgitation: sour or bitter liquid or food coming back into the throat or mouth.
- A lump-in-the-throat feeling or trouble swallowing.
- A chronic cough, hoarseness or frequent throat clearing, especially in the morning.
- Chest discomfort that isn’t clearly tied to exercise.
- Disrupted sleep, including waking up coughing or with a sour taste.
Heartburn or heart trouble?
This is the most important point in this article. Heart problems can feel like heartburn, and heartburn can feel like a heart problem. Chest pain or pressure that spreads to the arm, jaw, neck or back, or that comes with shortness of breath, sweating, nausea or lightheadedness, is an emergency. Call 911. Don’t drive yourself, and don’t wait to see if an antacid works.

What causes reflux and makes it worse
GERD rarely has a single cause. More often, several factors stack up. Common ones include:
- Large or late meals, especially eating within a few hours of bedtime.
- Certain foods and drinks that bother many people: fatty or fried food, spicy dishes, chocolate, peppermint, citrus, tomato-based sauces, coffee, alcohol and carbonated drinks. Triggers vary a lot from person to person.
- Extra weight around the middle, which puts pressure on the stomach.
- Smoking, which weakens the valve at the bottom of the esophagus.
- Pregnancy.
- A hiatal hernia, where part of the stomach pushes up through the diaphragm.
- Some medications, which can relax the valve or irritate the esophagus. Never stop a prescribed medicine on your own; ask your doctor first.
Everyday steps that often help
For many people, small changes make a real difference. These are commonly recommended first steps:
- Eat smaller meals and slow down at the table.
- Leave about two to three hours between your last meal and lying down.
- Raise the head of your bed a few inches, or use a wedge pillow, so gravity works in your favor at night. Stacking regular pillows usually doesn’t do the job.
- Keep a simple food and symptom log for two weeks to spot your personal triggers.
- Cut back on alcohol and quit smoking, both of which can make reflux worse.
Over-the-counter remedies can ease occasional symptoms, but if you find yourself reaching for them most days, or for more than a couple of weeks, it’s time to talk with a doctor rather than keep treating it on your own. Good guidance on food and habits is part of the picture, and our nutrition and diet advice can help you build a plan that fits how you actually eat.
Warning signs you shouldn’t ignore
See a doctor promptly if heartburn comes with any of the following:
- Trouble swallowing, pain when swallowing, or food that feels stuck
- Vomiting, especially vomit with blood or that looks like coffee grounds
- Black, tarry stools
- Weight loss you can’t explain
- A cough, hoarseness or wheezing that won’t go away
- Symptoms that started for the first time later in life, or that keep coming back despite treatment
Left alone for years, frequent acid exposure can lead to inflammation of the esophagus, narrowing that makes swallowing hard, and a change in the lining called Barrett’s esophagus. A doctor can decide whether you need further testing or a referral to a gastroenterologist.
Getting reflux checked: the usual way vs. with your own doctor
Reflux is the kind of problem that tends to drift. It’s not quite urgent, so it gets pushed to the next appointment, and the next one is weeks away. Here is how that often plays out, compared with having a doctor you can reach directly.
Chest burning on a Saturday night
The usual way: you’re unsure if it’s dinner or your heart, so you either sit up worrying or head to an emergency room and spend the night there.
With your own doctor: a Wave member can call or text their doctor any time, weekends included, and talk it through. If the symptoms sound like an emergency, the advice is clear: call 911. If it sounds like reflux, you get practical next steps and a visit the same or next day.
Ruling out the heart
The usual way: a referral, a wait for a cardiology appointment, and another wait for results.
With your own doctor: at our Boynton Beach office, an EKG and labs are done in the same building, and cardiology is on location, including stress tests, so your doctor can look at the heart side of the question without sending you across Palm Beach County.
When you need a specialist
The usual way: you call around for a gastroenterology appointment, fill out new paperwork and repeat your story from the beginning.
With your own doctor: through our specialist referrals, we normally get you in the same day, your records are sent ahead, and your doctor reviews the results with you afterward. A dedicated concierge liaison handles the booking and paperwork.
Reflux and heart rhythm problems can both cause unsettling chest sensations. If a fluttering or racing heartbeat is part of what you feel, our explainer on AFib symptoms is worth a read.
Why it’s worth getting answers
GERD is common, and for most people it is very manageable once the pattern is clear. The trouble is living with it for years because it never felt serious enough for an appointment. Whether you live in Boynton Beach, Delray Beach, Boca Raton or Palm Beach, having a doctor who knows your history, your medications and your habits makes it far easier to figure out what’s driving your symptoms and keep them in check. Members also keep one up-to-date medication list, with prescriptions sent to their nearest pharmacy.
