Learn about the causes, symptoms, and types of esophageal ulcers, how they’re diagnosed, and the best treatment options including medication, endoscopy, and surgery.

A burning discomfort in the center of the chest, discomfort when swallowing, or a persistent case of heartburn that just won’t quit — these are the kinds of symptoms that often bring people to their doctor’s office, only to learn the cause is something they’d never heard of before: an esophageal ulcer. While the name can sound alarming, esophageal ulcers are a well-understood condition, and for most patients, timely treatment leads to a full recovery.

What Is an Esophageal Ulcer?

The esophagus is the muscular tube that connects your throat to your stomach, allowing food and liquid to travel down to be digested. Like the rest of your digestive tract, the esophagus is lined with a protective layer of mucus. An esophageal ulcer forms when this lining breaks down, leaving an open sore in the esophageal wall, most often near the point where the esophagus meets the stomach.

Esophageal ulcers are considered a type of peptic ulcer, a broader category that also includes ulcers of the stomach and the upper part of the small intestine. While they can be painful and disruptive, esophageal ulcers are generally very treatable once properly diagnosed, and complications are uncommon when the condition receives timely medical attention.

What Are the Causes of Esophageal Ulcers?

Esophageal ulcers develop when something repeatedly irritates or damages the esophageal lining faster than it can heal. The most frequent causes include:

• Acid reflux and GERD. By far the most common cause, gastroesophageal reflux disease (GERD) occurs when the valve between the stomach and esophagus doesn’t close properly, allowing stomach acid to repeatedly wash back up into the esophagus. Over time, this steady acid exposure wears away the protective lining.
• Medications. Certain drugs can irritate the esophagus directly, especially if they aren’t swallowed with enough water or if a person lies down too soon afterward. Common culprits include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, certain antibiotics (particularly doxycycline), bisphosphonates used for bone health, and some supplements, including iron and potassium tablets.
• Infections. In people with weakened immune systems, such as those living with HIV, undergoing chemotherapy, or recovering from an organ transplant, infections from organisms like Candida (a type of yeast), herpes simplex virus, or cytomegalovirus can lead to ulcer formation. These infections are far less common in people with healthy immune systems.
• Irritant or injury-related causes. Smoking, heavy alcohol use, swallowing very hot foods or drinks, or accidentally ingesting a corrosive substance can all directly injure the esophageal lining.
• Autoimmune and inflammatory conditions. Less commonly, conditions such as Crohn’s disease or certain autoimmune skin disorders can involve the esophagus and lead to ulcer formation.
• Prior treatment or procedures. Radiation therapy to the chest, certain endoscopic procedures, or recovery from esophageal surgery can occasionally result in ulcers as the tissue heals.

It’s worth noting that stress and spicy food, once widely blamed for ulcers, are no longer considered direct causes. They may worsen symptoms in someone who already has an ulcer, but they don’t cause the underlying damage on their own.

What Are the Symptoms of Esophageal Ulcers?

The hallmark symptom of an esophageal ulcer is a burning pain behind or below the breastbone (sternum), which can range from mild to quite severe. Other symptoms commonly include:

• Heartburn or acid reflux
• Nausea or vomiting, which may occasionally contain blood
• Pain or difficulty swallowing
• A sensation of a lump in the throat
• Indigestion or bloating
• Loss of appetite and unintentional weight loss
• A sour taste in the mouth
• A dry cough or sore throat

It’s also worth knowing that some people with an esophageal ulcer experience no symptoms at all, which is one of several reasons it’s important not to ignore persistent digestive discomfort, even if it seems mild.

What Are the Types of Esophageal Ulcers?

Rather than being classified by appearance, esophageal ulcers are generally categorized by their underlying cause, since this is what guides diagnosis and treatment:

• Reflux-related ulcers, caused by chronic acid exposure from GERD, are the most common type and typically occur in the lower esophagus, near the junction with the stomach.
• Medication-induced (or “pill”) ulcers form when a pill irritates the esophageal wall, most often in the middle of the esophagus.
• Infectious ulcers, caused by fungal, viral, or other infections, are seen primarily in people with compromised immune systems.
• Ulcers from caustic injury, resulting from swallowing an irritating or corrosive substance.
• Autoimmune or inflammatory ulcers, associated with conditions such as Crohn’s disease or certain immune-mediated skin disorders that also affect the esophagus.
• Ulcers related to prior treatment, including those that follow radiation therapy, certain endoscopic procedures, or esophageal surgery.

Identifying which category an ulcer falls into is a key part of the diagnostic process, since treatment differs significantly depending on the underlying cause.

How Are Esophageal Ulcers Diagnosed?

If your doctor suspects an esophageal ulcer, diagnosis typically starts with a detailed conversation about your symptoms, medical history, and any medications or supplements you’re taking. From there, the most common diagnostic tools include:

• Upper endoscopy. Considered the gold standard for diagnosis, this procedure involves passing a thin, flexible tube with a small camera down the throat to directly examine the esophageal lining. It allows your doctor to see the ulcer, assess its size and location, and, if needed, take a small tissue sample (biopsy) to rule out infection or malignancy.
• Barium swallow (esophagram). In this imaging test, you swallow a contrast liquid that coats the esophagus, making ulcers and irregularities visible on X-ray. This may be used as an alternative when endoscopy isn’t readily available.
• Laboratory testing. If an infection or autoimmune condition is suspected, blood tests or specialized studies on a biopsy sample may help confirm the specific cause.

A thorough diagnostic workup matters because esophageal ulcers with very different causes, an infection versus a medication reaction versus GERD, can sometimes look quite similar on the surface, even though their treatments are not interchangeable.

How Are Esophageal Ulcers Treated?

Treatment is tailored to the underlying cause, but most patients see meaningful improvement within days to weeks of starting appropriate therapy.

• For reflux-related ulcers, treatment typically centers on reducing stomach acid with proton pump inhibitors (PPIs) or H2 receptor blockers, allowing the esophageal lining time to heal. In more severe or persistent cases, your doctor may discuss surgical options.
• For medication-induced ulcers, the offending medication is usually stopped or replaced with an alternative, alongside acid-suppressing therapy to support healing. Patients are also counseled on safer pill-taking habits, such as swallowing tablets with a full glass of water and remaining upright for at least 30 minutes afterward.
• For infectious ulcers, treatment depends on the specific organism involved and may include antifungal, antiviral, or antibiotic medications.
• For ulcers linked to autoimmune or inflammatory conditions, treatment focuses on managing the underlying disease, often in coordination with a specialist such as a gastroenterologist or dermatologist.
• For ulcers caused by caustic ingestion, prompt emergency evaluation is essential, as these cases require close monitoring for complications such as perforation.

Across nearly all cases, doctors also recommend supportive lifestyle measures: eating smaller, more frequent meals, avoiding lying down for a few hours after eating, staying well hydrated, and limiting alcohol and tobacco use. It’s important to take the full course of any prescribed medication, even if symptoms improve early, to allow the ulcer to heal completely and reduce the chance of recurrence.

How Can Esophageal Ulcers Be Prevented?

While not every esophageal ulcer can be prevented, several everyday habits can meaningfully lower your risk:

• Manage acid reflux proactively. If you experience frequent heartburn, don’t wait for it to become severe. Speak with your doctor about lifestyle adjustments or medication before chronic reflux has a chance to damage the esophageal lining.
• Take pills safely. Always swallow tablets and capsules with a full glass of water, and remain upright for at least 30 minutes afterward. Avoid taking pills right before lying down.
• Watch your diet and habits. Limiting alcohol, avoiding tobacco, and steering clear of very hot foods or beverages all help protect the esophageal lining.
• Maintain a healthy weight. Excess weight increases abdominal pressure, which can worsen acid reflux and, over time, raise the risk of ulcer formation.
• Don’t ignore persistent symptoms. Ongoing heartburn, difficulty swallowing, or unexplained chest discomfort deserve a medical evaluation rather than being managed indefinitely with over-the-counter remedies alone.
• Talk to your doctor about your medications. If you take NSAIDs, certain antibiotics, or bisphosphonates regularly, ask whether any precautions are recommended for your specific situation.

When to Seek Immediate Medical Care

While most esophageal ulcers are manageable with routine care, certain symptoms signal a medical emergency and require immediate attention. Seek emergency care right away if you experience:

• Vomiting blood, or vomit that resembles coffee grounds
• Black, tarry stools, or visible blood in the stool
• Sudden, severe chest pain
• Difficulty breathing
• A rapid heartbeat alongside these symptoms
• Known ingestion of a corrosive or toxic substance

These symptoms can indicate serious complications such as significant bleeding or a perforation in the esophageal wall, both of which require prompt evaluation.

An esophageal ulcer diagnosis can understandably feel unsettling, but the outlook for most patients is genuinely reassuring. With an accurate diagnosis, the right treatment for the underlying cause, and a few supportive lifestyle changes, the large majority of esophageal ulcers heal completely, often without any lasting effects.
