Heartburn is a burning feeling behind the breastbone, often with a sour or bitter taste in the back of the throat. It happens when the muscle valve at the bottom of the esophagus does not close all the way and stomach acid washes back up. Your stomach is built to handle that acid. Your esophagus is not, which is why it burns. Most episodes come after a large meal or while lying down, and most are not emergencies. A few are, and the difference is worth knowing before you are lying awake at 2 a.m. trying to decide.
Heartburn or a heart attack?
Here is the honest answer we give patients: you cannot reliably tell the difference at home, and neither can we over the phone.
Heartburn usually burns, follows a meal, comes with a sour taste, and often eases when you sit up. Heart attack pain tends to feel like pressure, squeezing, or tightness, and it may spread to the jaw, neck, back, or either arm. It often arrives with sweating, shortness of breath, nausea, or lightheadedness.
Two things trip people up. Antacid relief does not rule out a heart problem, and plenty of heart attacks feel exactly like bad indigestion, especially in women, older adults, and people living with diabetes. If your chest pain is new, severe, or different from your usual heartburn, come in. An EKG and a blood test settle the question quickly. Call 911 rather than driving yourself.
Signs that mean go to the ER now
Come in immediately if you have:
- Chest pressure or tightness with sweating, shortness of breath, or pain spreading to the jaw, arm, or back
- Vomit that contains blood or looks like coffee grounds
- Black, tarry, or bloody stools
- Trouble swallowing, painful swallowing, or food that feels stuck
- Chest pain that wakes you from sleep or comes on with exertion
- Severe upper belly pain during pregnancy, particularly with headache, vision changes, or swelling
Heartburn so bad you throw up
Reflux can absolutely cause nausea and vomiting, and a rough night of it does not automatically mean something is badly wrong. What matters is what comes up and what comes with it.
Blood or dark, gritty material in your vomit is an emergency every time. Forceful repeated vomiting can also tear the lining of the esophagus and cause bleeding on its own. And when vomiting arrives alongside severe pain, fever, or a rigid belly, we look beyond reflux at the gallbladder, pancreas, ulcers, and blockages, which is why our on-site lab and imaging matter for this symptom. If you cannot keep liquids down for a full day, dehydration becomes its own problem.
How long should heartburn last?
A single episode usually runs from a few minutes to a couple of hours and fades once the acid clears and your stomach empties. That is the normal pattern.
The pattern that needs attention is heartburn two or more times a week, or heartburn that keeps returning for several weeks. That is chronic reflux rather than an occasional bad meal, and left alone, ongoing acid exposure can inflame and narrow the esophagus, make swallowing difficult, and change the cells lining it. Needing antacids most days for more than two weeks is a signal to get evaluated, not to buy a bigger bottle.
How to get rid of heartburn
Antacids work fast but wear off fast. Acid reducers such as famotidine last longer, and daily medications that shut down acid production are meant for frequent reflux under a provider’s guidance rather than indefinite self-treatment.
Habits do more than most people expect:
- Stop eating about three hours before bed
- Raise the head of your bed six to nine inches, which works better than stacking pillows
- Eat smaller, lower-fat meals
- Track your own triggers, commonly coffee, alcohol, citrus, tomato, chocolate, mint, onions, and spicy food
- Skip tight belts and waistbands
- Quit smoking, which weakens that valve directly
Heartburn during pregnancy is common, especially late on, and the habit changes above are usually the safest first step.
