Heartburn affects millions of people worldwide and is often caused by stomach acid flowing back into the esophagus, leading to a burning sensation in the chest1 2. While occasional heartburn is common and usually manageable with lifestyle changes, frequent or severe heartburn may indicate a more serious condition such as gastroesophageal reflux disease (GERD) 34. Understanding the causes of sudden heartburn and recognizing when to seek medical help is essential for proper management and prevention of complications5 .
Medical Conditions That Cause Heartburn
Heartburn is commonly a symptom of several medical conditions affecting the digestive system. These conditions can cause acid reflux or irritation in the esophagus, leading to the characteristic burning sensation.
Anxiety can worsen heartburn symptoms by affecting the digestive system and muscle function. It may reduce the pressure on the lower esophageal sphincter (LES), the muscle that prevents stomach acid from flowing back into the esophagus6 7. Anxiety can also increase stomach acid production and cause muscle tension around the stomach, pushing acid upward6 7. There is a bidirectional relationship between GERD and anxiety, where each condition can exacerbate the other8 36. Managing both anxiety and heartburn together may be necessary for optimal relief4 7.
Barrett's esophagus is a precancerous condition that can develop from untreated or chronic GERD6 7. It involves changes in the lining of the esophagus due to repeated acid exposure. Barrett's esophagus increases the risk of esophageal cancer and requires medical monitoring4 7. Patients with long-standing reflux symptoms, especially at night, smoking history, or family history of Barrett's esophagus, are at higher risk9 .
Esophagitis is inflammation of the esophagus lining, often caused by acid reflux4 7. It can result in burning pain similar to heartburn and may lead to complications such as ulcers or scarring if untreated6 7. Causes include GERD, infections, certain medications, and allergic reactions10 . Persistent esophagitis requires medical evaluation and treatment to prevent further damage.
GERD is the most common cause of frequent heartburn and acid reflux3 64. It occurs when the LES weakens or relaxes inappropriately, allowing stomach acid to flow back into the esophagus1 10. Risk factors include advanced age, male sex, white race, abdominal obesity, tobacco use, and pregnancy7 9. GERD symptoms include frequent heartburn, regurgitation, and sometimes cough or wheezing4 7. Untreated GERD can lead to complications such as Barrett's esophagus and esophageal strictures6 7.
Gastroparesis is a condition where the stomach empties slowly, causing delayed digestion9 . This can increase stomach pressure and acid production, contributing to acid reflux and heartburn-like symptoms9 . It is often associated with diabetes and other conditions affecting stomach motility9 . Diagnosis may involve tests such as an esophagram or gastric emptying studies9 .
A hiatal hernia occurs when the upper part of the stomach pushes through the diaphragm into the chest cavity11 9. This disrupts the normal function of the LES and allows acid reflux to occur more easily11 9. Hiatal hernias are common, especially with aging, and can worsen GERD symptoms11 9. They may require surgical repair if severe or complicated9 .
Pregnancy increases the risk of heartburn due to hormonal changes and increased abdominal pressure6 79. The hormone progesterone relaxes the LES, allowing acid to reflux into the esophagus9 . As pregnancy progresses, symptoms often worsen9 . Lifestyle modifications and safe medications can help manage heartburn during pregnancy12 .
Stomach ulcers are open sores in the stomach lining that can cause burning pain and discomfort4 7. While ulcers primarily cause upper abdominal pain, they may sometimes be mistaken for heartburn4 7. Ulcers can result from acid damage, infection with Helicobacter pylori, or use of nonsteroidal anti-inflammatory drugs (NSAIDs) 5. Proper diagnosis and treatment are important to prevent complications.
- Common medical conditions causing heartburn include:
- Anxiety and stress-related LES dysfunction6 7
- Barrett's esophagus as a complication of chronic GERD6 7
- Esophagitis from acid irritation or infection4 7
- GERD due to LES weakness or hiatal hernia3 64
- Gastroparesis causing delayed stomach emptying9
- Hiatal hernia disrupting the antireflux barrier11 9
- Pregnancy-related hormonal and pressure changes9
- Stomach ulcers causing upper digestive tract pain4 7
“Gastroesophageal reflux disease means that the acid which normally lives in the stomach is flowing backwards or refluxing into the esophagus.”

Heartburn-Like Pain From Other Conditions
Not all burning chest pain is caused by heartburn or acid reflux. Several other medical conditions can cause symptoms that mimic heartburn and require different management.
Gallstones are solid particles, often made of cholesterol, that form in the gallbladder6 7. They can cause symptoms similar to heartburn, especially if they block the bile duct6 7. Symptoms include indigestion, heartburn-like pain after meals, jaundice (yellowing of the skin and eyes), and severe abdominal or chest pain that worsens when lying down6 7. Gallstone complications can be serious and require prompt medical attention6 7.
💡 Did You Know?
Heartburn that occurs more than twice a week may be a sign of GERD, which affects about 20% of adults in the U.S. 713.
Heart disease, including angina and heart attacks, can present with chest pain that is often mistaken for heartburn6 7. Women may experience heart attack symptoms such as chest pain, back pain, and jaw pain that resemble heartburn, leading to delayed diagnosis4 7. Severe chest pain, especially when accompanied by shortness of breath, sweating, or pain radiating to the arm or jaw, requires immediate emergency care6 7.
Other conditions that can cause heartburn-like pain include stomach ulcers, pancreatitis, and esophageal motility disorders4 75. It is important to differentiate these from heartburn to ensure appropriate treatment.
- Conditions causing heartburn-like pain:
- Gallstones causing bile duct obstruction and indigestion6 7
- Heart disease presenting with chest pain similar to heartburn6 7
- Other digestive or esophageal disorders mimicking heartburn4 7
Heartburn-like chest pain can be a sign of serious conditions such as gallstones or heart disease. Prompt evaluation is crucial if chest pain is severe, persistent, or accompanied by other symptoms like difficulty breathing or sweating6 7.
Dietary Triggers of Heartburn
Diet plays a significant role in the development and worsening of heartburn symptoms. Certain foods and eating habits can trigger acid reflux by relaxing the LES or increasing stomach acid production.
- Common dietary triggers include:
- Fatty, greasy, and spicy foods4 7
- Highly acidic foods such as citrus fruits and tomatoes4 7
- Eating or drinking too quickly4 7
- Large meals or calorie-dense foods5
- Lying down soon after eating4 7
Eating smaller, more frequent meals and avoiding food for at least three hours before bedtime can reduce the frequency and severity of heartburn4 7. Additionally, raising the head of the bed and avoiding tight clothing around the waist can help prevent reflux12 .
Heartburn Symptoms Specific to Women
Women may experience heartburn symptoms differently or more frequently than men. Studies suggest women report heartburn and regurgitation more often and may be more likely to seek medical attention4 7. Pregnancy is a common cause of heartburn in women due to hormonal changes and increased abdominal pressure9 .
Women may also experience heart attack symptoms that mimic heartburn, such as chest pain, back pain, and jaw pain, which can lead to delayed diagnosis and treatment4 7.
- Key points about heartburn in women:
- Women report heartburn and regurgitation more frequently than men4 7
- Pregnancy increases risk due to hormonal and pressure changes9
- Heart attack symptoms in women can resemble heartburn4 7
When to See a Doctor for Heartburn
While occasional heartburn is common, certain symptoms and patterns warrant medical evaluation to rule out serious conditions and guide treatment.
Consult a healthcare provider if you experience:
- Heartburn more than twice a week4 7
- Symptoms that persist despite lifestyle changes and medication4 7
- Difficulty swallowing or persistent nausea and vomiting4 7
- Unintentional weight loss or poor appetite4 7
- Blood in vomit or black, tarry stools indicating gastrointestinal bleeding4 7
- Chest pain that feels burning, crushing, or squeezing, which could indicate a heart attack4 7
- Chronic cough or wheezing that may be related to GERD4 7
Early consultation helps differentiate heartburn from other serious conditions such as heart disease or cancer and allows for appropriate treatment4 7.
“One very important thing to remember is that when patients have classic symptoms of reflux such as heartburn, regurgitation and if the esophageal lining changes from normal lining to Barrett's esophagus, those symptoms may disappear.”

Heartburn Summary and Key Points
Heartburn is a common symptom caused primarily by acid reflux due to LES dysfunction or other medical conditions. While often manageable with lifestyle changes and medications, persistent or severe heartburn may indicate GERD or other serious conditions such as Barrett's esophagus, gallstones, or heart disease.
- Heartburn is caused by stomach acid backing up into the esophagus due to LES weakness or other factors1 10.
- Anxiety and stress can worsen heartburn by affecting LES pressure and acid production6 7.
- Dietary factors like fatty, spicy, and acidic foods, as well as eating habits, influence heartburn frequency4 75.
- Women may experience heartburn differently and are at risk during pregnancy4 79.
- Seek medical care for frequent, severe, or atypical symptoms to prevent complications4 7.
Proper diagnosis often involves history-taking, imaging, and endoscopy to assess esophageal damage and rule out other causes4 7. Treatment includes lifestyle modifications, medications such as antacids, H2 blockers, and proton pump inhibitors, and sometimes surgery for severe cases4 710.
