That burning feeling behind the breastbone after a big meal is familiar to most people. Acid reflux, where stomach acid travels back up into the food pipe, is extremely common and usually harmless. But because reflux can mimic other conditions, including heart and stomach problems, it's worth knowing when burning pain is ordinary heartburn and when it's a signal to get checked.
Typical signs of acid reflux
- A burning sensation in the chest or upper abdomen, often after eating.
- Symptoms that worsen when lying down or bending over.
- A sour or bitter taste in the mouth, or regurgitation of food.
- A persistent dry cough, hoarseness, or the feeling of a lump in the throat.
- Symptoms triggered by spicy or fatty foods, large meals, alcohol, or caffeine.
When reflux becomes a recurring problem
Occasional heartburn is normal. When reflux happens frequently, it's often called GERD (gastroesophageal reflux disease). Persistent reflux deserves attention because, over time, repeated acid exposure can irritate or damage the food pipe. Lifestyle changes are usually the first step, but ongoing symptoms should be reviewed rather than masked indefinitely with over-the-counter remedies.
Causes that can feel like reflux
- Stomach ulcers: gnawing or burning upper-abdominal pain, sometimes worse when hungry or at night.
- Gastritis: inflammation of the stomach lining causing upper pain, nausea, and fullness.
- Gallbladder problems: upper-right pain after fatty meals.
- Heart problems: chest pressure or pain, especially with exertion, sweating, or breathlessness, which can be mistaken for heartburn.
Lifestyle steps that help reflux
- Eat smaller meals and avoid lying down for two to three hours after eating.
- Identify and limit your trigger foods and drinks.
- Raise the head of the bed and avoid eating late at night.
- Maintain a healthy weight and avoid smoking.
- Use over-the-counter antacids only as directed; a pharmacist can advise what suits you and whether longer-term treatment needs a doctor.
Warning signs that need prompt or emergency care
Call 911 (US/Canada), 999 (UK), or 112 (EU) for chest pain with sweating, breathlessness, or pain spreading to the arm or jaw, since this can be a heart problem rather than heartburn. See a doctor promptly for difficulty or pain when swallowing, food getting stuck, vomiting blood, black or tarry stools, unexplained weight loss, or persistent vomiting.
When to see a doctor
- Reflux symptoms more than twice a week or lasting several weeks.
- Symptoms that need regular over-the-counter medication to control.
- New reflux symptoms if you are over 50.
- Any of the warning signs above.
Because burning upper-abdominal pain has several possible causes, a clinician can help distinguish simple reflux from conditions that need further testing and tailor treatment to you.
