Heartburn

Heartburn is a painful burning sensation caused by stomach acid backing up into the esophagus, which may indicate a need for medical treatment.

Overview

Heartburn is a painful burning feeling in your chest or throat. It happens when stomach acid backs up into your esophagus, the tube that carries food from your mouth to your stomach.

Risk Factors and Complications

If you have heartburn more than twice a week, you may have GERD. But you can have GERD without having heartburn. Pregnancy, certain foods, alcohol, and some medications can bring on heartburn. Treating heartburn is important because over time reflux can damage the esophagus.

Treatment

Over-the-counter medicines may help. If the heartburn continues, you may need prescription medicines or surgery.

Warning

If you have other symptoms such as crushing chest pain, it could be a heart attack. Get help immediately.

Frequently Asked Questions

Spicy foods, citrus, tomato‑based sauces, chocolate, caffeine, carbonated drinks, and fatty meals are common culprits. Eat your last large meal at least 3 hours before lying down, keep the bedroom cool, elevate the head of the bed 6‑10 inches, and avoid alcohol or nicotine in the evening.
Pregnancy‑related heartburn is common due to hormonal relaxation of the lower esophageal sphincter. Safe measures include small frequent meals, avoiding trigger foods, staying upright after eating, and using antacids that contain calcium carbonate (e.g., Tums) as directed. If symptoms persist, your obstetrician may prescribe a low‑dose H2 blocker such as ranitidine‑free alternatives after confirming safety.
If you experience heartburn two or more times a week, especially if it wakes you at night or interferes with daily activities, you should schedule a visit with your primary care provider. Persistent symptoms may indicate gastro‑esophageal reflux disease (GERD) that requires prescription therapy or further testing.
Occasional use of antacids (e.g., calcium carbonate) is fine, but daily use of H2 blockers or proton‑pump inhibitors for more than 8‑12 weeks should be discussed with a clinician. Long‑term use can increase risks of nutrient malabsorption, kidney issues, and infections, so a doctor may recommend stepping down therapy or adding lifestyle changes.
