Heartburn is a burning feeling behind the breastbone caused by stomach acid backing up into the esophagus. Occasional heartburn usually responds to antacids and diet changes and can be managed with telemedicine or your primary care doctor. But because heartburn can be hard to tell apart from a heart attack, go to the ER, such as Bellaire ER on Bellaire Blvd near you in Houston, if chest pain is severe, spreads to your arm, jaw, or back, comes with shortness of breath or sweating, or does not ease with antacids.

Symptoms

  • Burning sensation behind the breastbone: A hot or burning feeling in the center of the chest, often rising toward the throat.
  • Sour or acidic taste: Stomach acid or a bitter, sour taste backing up into the throat or mouth (regurgitation).
  • Worse after eating or lying down: Discomfort that flares after large or fatty meals, or when bending over or lying flat.
  • Burning in the throat: Irritation, hoarseness, or a lump-like feeling in the throat from acid exposure.
  • Nighttime symptoms: Reflux that disrupts sleep or triggers a chronic cough or wheezing.

When It's an Emergency

Visit the ER for heartburn if:

Your symptoms are severe, sudden, or getting worse. Don't wait — walk in to Bellaire ER or call (713) 660-0001.

Heartburn and a heart attack can feel alike, and it is not always possible to tell them apart at home. Call 911 or go to the nearest emergency room if chest pain or pressure is severe, lasts more than a few minutes, or spreads to the arm, jaw, neck, or back. These can be signs of a heart attack, not simple reflux.

Also seek emergency care right away if chest discomfort comes with shortness of breath, sweating, nausea, lightheadedness, or a racing or irregular heartbeat. Do not wait to see if the feeling passes, and do not drive yourself.

Go to the ER for digestive red flags too: trouble or pain when swallowing, food that feels stuck, vomiting blood or material that looks like coffee grounds, black or tarry stools, or unexplained weight loss. These can point to bleeding, a narrowed esophagus, or another serious problem.

If you are unsure whether your symptoms are heartburn or something more serious, treat it as an emergency. Bellaire ER is open 24/7 at 5302 Bellaire Blvd and can quickly rule out a cardiac cause.

When It's Not an Emergency

Occasional heartburn after a large, spicy, or fatty meal is common and usually not an emergency. Mild, familiar symptoms often ease with an over-the-counter antacid, staying upright after eating, and avoiding known trigger foods.

If your symptoms are mild and you have no cardiac warning signs, a telemedicine visit or your primary care doctor is a reasonable place to start. They can review your triggers, suggest an acid-reducing medication, and arrange follow-up.

Frequent heartburn, two or more times a week, may be gastroesophageal reflux disease (GERD) and is worth discussing with a doctor, but it is typically handled in an outpatient setting rather than the ER. Seek urgent evaluation only if red-flag symptoms appear or the pain could be your heart.

What Happens at Bellaire ER

When you arrive at Bellaire ER with chest discomfort, you are seen quickly by a board-certified emergency physician. Because heartburn and a heart attack can look the same, we first work to rule out a cardiac cause, often with an ECG (heart tracing) and blood tests.

Our on-site lab, X-ray, CT, and ultrasound let us evaluate your heart, lungs, and digestive tract without sending you elsewhere. This helps us distinguish reflux from conditions such as a heart attack, gallbladder disease, or an ulcer.

If your symptoms are from acid reflux, we can provide medication to calm the burning and relieve discomfort. We diagnose and treat in a single visit, and most patients do not need a hospital transfer. Before you leave, your physician explains your results and gives a clear follow-up plan.

Prevention

You can reduce heartburn by eating smaller meals and avoiding common triggers such as fatty or fried foods, spicy dishes, chocolate, caffeine, alcohol, and carbonated drinks.

Stay upright for two to three hours after eating and avoid late-night meals. Raising the head of your bed and sleeping on your left side can reduce nighttime reflux.

Maintaining a healthy weight, not smoking, and wearing loose-fitting clothing around the waist can also lessen symptoms. If heartburn keeps returning despite these steps, talk with a doctor about longer-term treatment.

Frequently Asked Questions

When should I go to the ER for heartburn?

Go to the ER if chest pain is severe, lasts more than a few minutes, spreads to your arm, jaw, neck, or back, or comes with shortness of breath, sweating, or nausea, because these can signal a heart attack rather than heartburn. Also seek emergency care for trouble swallowing, food that feels stuck, vomiting blood, or black, tarry stools. When in doubt, treat unexplained chest pain as an emergency and get it checked.

How can I tell the difference between heartburn and a heart attack?

You often cannot tell them apart reliably on your own, which is why chest pain should be taken seriously. Heartburn usually causes a burning feeling behind the breastbone that is worse after meals or when lying down and may improve with an antacid. A heart attack more often causes pressure or tightness that may spread to the arm or jaw and comes with shortness of breath, sweating, or nausea. If you have any doubt, call 911 or go to the ER.

What are the symptoms of heartburn?

Heartburn typically feels like a burning sensation behind the breastbone that may rise toward the throat, often after eating or when lying down. Many people also notice a sour or acidic taste in the mouth from acid backing up (regurgitation). Some have throat irritation, hoarseness, or a chronic cough. Symptoms that occur more than twice a week may indicate GERD and are worth discussing with a doctor.

What happens when I visit Bellaire ER for heartburn?

A board-certified emergency physician evaluates you quickly and, because heartburn can mimic a heart attack, usually starts by ruling out a cardiac cause with an ECG and blood tests. Using our on-site lab and imaging (X-ray, CT, and ultrasound), we can distinguish reflux from more serious conditions. If it is acid reflux, we provide medication for relief and a follow-up plan, all in a single visit, and most patients do not need a hospital transfer.
