Is It Heartburn or Something Else? How to Tell

Many people occasionally experience a burning sensation in their chest, commonly known as heartburn, often after eating certain foods or lying down. This sensation can be uncomfortable and concerning, prompting questions about its cause. While heartburn is a frequent occurrence linked to acid reflux, similar feelings can sometimes signal other, potentially more serious, health conditions. Differentiating it from other conditions with similar symptoms is crucial for self-care and knowing when to seek medical help.

Understanding Heartburn

Heartburn manifests as a burning discomfort felt behind the breastbone, sometimes extending up towards the neck and throat. This sensation is a symptom of acid reflux, occurring when stomach acid flows backward into the esophagus. The esophagus lacks the protective lining found in the stomach, making it vulnerable to irritation from this acid.

Acid reflux involves the lower esophageal sphincter (LES), a muscle at the bottom of the esophagus. Normally, the LES opens to allow food into the stomach and then closes to prevent stomach contents from re-entering the esophagus. When this muscle weakens or relaxes inappropriately, stomach acid can reflux, causing heartburn. Common triggers include consuming large meals, lying down too soon after eating, certain foods like fatty or spicy dishes, coffee, chocolate, citrus products, and alcohol. Being overweight, smoking, and stress can also contribute to symptoms.

Conditions That Mimic Heartburn

Several medical conditions can produce symptoms that are easily confused with heartburn, making accurate self-assessment challenging.

Gastroesophageal Reflux Disease (GERD) is a chronic, severe form of acid reflux, diagnosed when symptoms occur frequently (more than twice a week for several weeks). Unlike occasional heartburn, GERD can lead to complications such as inflammation of the esophageal lining or narrowing of the esophagus over time.

Indigestion (dyspepsia) includes general discomfort in the upper abdomen. While heartburn is a specific burning sensation caused by acid reflux, indigestion can involve feelings of fullness, bloating, nausea, or belching, and does not always stem from acid. Both conditions share some triggers, such as certain foods and large meals.

Esophageal spasms are uncoordinated muscle contractions in the esophagus, causing chest pain that feels like squeezing or tightening behind the breastbone. This pain can be intense and sometimes mistaken for a heart attack. While the exact cause is unclear, these spasms are related to abnormal nerve function controlling swallowing muscles.

Peptic ulcers are open sores that develop on the inner lining of the stomach or the upper part of the small intestine. The pain from a peptic ulcer is often described as a dull or burning sensation in the upper abdomen, between the breastbone and the belly button. This pain can occur between meals or at night, potentially improving after eating for some individuals.

Anxiety or panic attacks can cause physical symptoms, including chest pain that is sharp, stabbing, or feels like tightness or pressure. These symptoms arise from the body’s stress response, involving a surge of hormones like adrenaline. While alarming, anxiety-related chest pain typically remains centered in the chest and may resolve within a short period.

When to Seek Medical Attention

Recognizing “red flag” symptoms is important for identifying when chest pain or heartburn-like sensations require immediate medical evaluation.

Severe chest pain, especially if it lasts more than a few minutes or spreads to the arm, back, neck, jaw, or stomach, could indicate a potential heart attack. Other urgent symptoms include shortness of breath, cold sweats, dizziness, or nausea.

Difficulty swallowing (dysphagia), where food feels stuck in the throat or chest, necessitates medical review. Painful swallowing (odynophagia), causing discomfort in the mouth, throat, or esophagus during swallowing, also requires professional assessment. These swallowing issues can sometimes signal underlying conditions.

Other concerning signs include unexplained weight loss, which may indicate a serious condition. The presence of black or bloody stools, or vomiting blood, suggests internal bleeding within the digestive tract and requires immediate medical attention. Heartburn that becomes more frequent, worsens, or does not improve with over-the-counter medications should prompt a consultation.
