GERD vs Heartburn: What's the Difference and When Should You Worry?

Written by Cherlie Joseph, MSN, FNP-BC · Medically reviewed by Naurah Gaspard, DNP, FNP-C, FNP-BC · Updated November 2026

Heartburn is a symptom: a burning feeling behind the breastbone when stomach acid backs up. GERD is a chronic condition in which reflux happens often enough, typically twice a week or more, to cause troublesome symptoms or damage the esophagus. Occasional heartburn is common; frequent heartburn deserves a closer look.

Heartburn is a symptom, GERD is a condition

Almost everyone gets heartburn now and then, often after a big or spicy meal. That occasional backflow of acid is called gastroesophageal reflux (GER). When reflux keeps happening and causes ongoing symptoms or complications, it is called gastroesophageal reflux disease (GERD).

	Occasional heartburn	GERD
How often	Now and then, usually after triggers	Typically twice a week or more, for weeks
Other symptoms	Usually just burning	Regurgitation, sour taste, cough, hoarseness, chest discomfort
Damage	Rarely	Can cause esophagitis, narrowing or Barrett’s esophagus
Usual treatment	Lifestyle tweaks, antacids	Lifestyle changes plus medicine, often a PPI

Symptoms of GERD beyond heartburn

Classic GERD symptoms are heartburn and regurgitation, where food or sour liquid comes back up into the throat or mouth. Some people have less obvious signs:

• A chronic cough or throat clearing
• Hoarseness, especially in the morning
• Nausea or a sour taste
• Feeling like there is a lump in the throat
• Chest discomfort that is not from the heart (which needs to be ruled out first)

How GERD is diagnosed

For many adults with classic heartburn and regurgitation and no warning signs, the diagnosis is made from symptoms. The ACG guideline suggests an 8-week trial of a once-daily proton pump inhibitor (PPI) taken before a meal. If symptoms improve, that supports GERD, and the next step is trying to lower the dose or stop.

Further testing is used when symptoms do not respond, are atypical or come with alarm signs. That can include an upper endoscopy to look at the esophagus, or a pH monitoring test that measures how often acid reaches the esophagus.

Treatment options

• Lifestyle changes: smaller meals, no eating 2 to 3 hours before bed, raising the head of the bed, weight loss if needed, and avoiding your personal trigger foods.
• Antacids for quick relief of occasional symptoms.
• H2 blockers such as famotidine for mild or predictable symptoms.
• PPIs such as omeprazole or pantoprazole for frequent symptoms or esophagitis.
• Newer options such as vonoprazan (Voquezna), a potassium-competitive acid blocker, which the FDA approved for erosive esophagitis in 2023 and for heartburn from non-erosive GERD in 2024.
• Procedures or surgery for selected people whose symptoms are not controlled with medicine.

A provider will review which option is appropriate based on your symptoms and history.

When to worry

Heartburn that is new after age 60, that keeps coming back despite treatment, or that comes with any red flag below should be checked in person. Long-standing GERD can lead to Barrett’s esophagus, a change in the esophageal lining that raises cancer risk, so years of untreated symptoms are worth discussing with a provider.

Frequently asked questions

How do I know if I have GERD or just heartburn?

If heartburn or regurgitation happens twice a week or more, keeps coming back over weeks, or causes symptoms like cough or hoarseness, it may be GERD. A provider can help confirm it.

Can GERD go away on its own?

Some people improve a lot with weight loss, quitting smoking and meal timing changes, and some can stop medicine. Others need ongoing treatment. GERD is usually managed rather than cured.

Is GERD serious?

Most GERD is very manageable. Left untreated for years, it can damage the esophagus, which is why frequent symptoms and any warning signs should be evaluated.
