Short answer: most cases of chronic heartburn and acid reflux are handled by a Gastroenterologist. Read on for the exceptions.

What this symptom means

Heartburn is a burning feeling behind the breastbone, often after eating or when lying down. Occasional heartburn is common and not concerning. When it happens more than twice a week, it is generally classified as gastroesophageal reflux disease (GERD) and deserves proper evaluation rather than indefinite antacid use.

Common causes

Gastroesophageal reflux disease (GERD)
Hiatal hernia
Certain foods, alcohol, and caffeine
Eating large meals or lying down after eating
Pregnancy
Some medications

Which doctor treats chronic heartburn and acid reflux?

Frequent heartburn is treated by a gastroenterologist, who can determine whether the esophagus has been affected. Because reflux and cardiac pain can feel similar, any chest burning that comes with exertion, sweating, or breathlessness should be treated as a possible heart problem first. A primary care physician can start treatment for straightforward cases.

When it may be urgent

Call 911 or go to the nearest emergency room if you experience any of the following.

Difficulty or pain when swallowing
Vomiting blood or material resembling coffee grounds
Black or tarry stools
Unintentional weight loss
Chest pain with sweating, breathlessness, or pain in the arm or jaw
