How long does it take for heartburn to go away?

[ebisimark0013]

Heartburn, the most common symptom of acid reflux, indigestion, and gastroesophageal reflux disease (GERD), also may occur with other diseases such as peptic ulcer disease. Heartburn is described as a substernal burning sensation that radiates upward toward the neck or throat.¹ For many individuals, heartburn is mild, infrequent, and predictable. For others, heartburn is frequent (occurs 2 or more days a week), persistent, and more severe.
