Heartburn / Acid Regurgitation
Heartburn is a burning feeling behind the breastbone, often rising toward the throat. It is commonly caused by reflux but chest pain must not automatically be assumed to be digestive.

Independent clinical validation is pending.
Quick Reference Facts
"Heartburn is a symptom, not a diagnosis; new or concerning chest pain must be assessed before it is attributed to reflux."
In simple words
Heartburn is a burning sensation behind the breastbone that may rise toward the throat. Regurgitation is the return of sour or bitter stomach contents into the throat or mouth. They are related but distinct symptoms.
Occasional heartburn may occur with gastroesophageal reflux. Frequent, troublesome, persistent, or complicated symptoms may indicate GERD or another disorder and should be assessed in clinical context.
Common Causes
- Gastroesophageal reflux, including GERD
- Pregnancy or increased abdominal pressure
- Meals, posture, smoking, or individual food and drink triggers that worsen reflux
- Functional heartburn or another esophageal disorder when objective reflux does not explain symptoms
Clinical Red Flags
Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:
- Chest pressure or pain with shortness of breath, sweating, faintness, or radiation to the arm, jaw, back, or shoulder: seek emergency assessment
- Progressive difficulty swallowing, painful swallowing, or food impaction
- Vomiting blood, black stools, or evidence of gastrointestinal bleeding or anemia
- Persistent vomiting or unexplained weight loss
Lifestyle & Diet Support
Avoid lying down for about 2–3 hours after eating, stop smoking, and identify personal triggers rather than applying a universal food-ban list. If overweight or obese, weight reduction can improve reflux symptoms. Persistent or recurrent symptoms should be reviewed by a clinician.
