Constant Burning? Why Your Stomach Is Ulcerating & Medical Next Steps

A constant burning feeling in your upper abdomen is not something to ignore. If it feels like fire just below your breastbone—especially if it worsens when your stomach is empty—you could be dealing with a stomach ulcer.

A stomach ulcer is a sore that forms in the lining of the stomach. It's also called a gastric ulcer, and it's a type of peptic ulcer disease. While ulcers are common and treatable, they can become serious if left untreated.

Let's break down why ulcers happen, what symptoms to watch for, and what medical steps you should take next.

What Is a Stomach Ulcer?

A stomach ulcer is an open sore that develops when the protective lining of the stomach is damaged. Normally, your stomach produces strong acid to digest food. A layer of mucus protects the stomach wall from that acid.

When that protective barrier weakens, acid can erode the tissue underneath. Over time, this creates a painful sore.

Think of it like a wound inside your stomach that is constantly exposed to acid.

Why Is Your Stomach Ulcerating?

There are two major causes of stomach ulcers:

1. Helicobacter pylori (H. pylori) Infection

This is a common bacterial infection. Many people carry H. pylori without knowing it, but in some cases, it damages the stomach lining and causes ulcers.

You can get H. pylori through:

• Contaminated food or water
• Close contact with infected individuals
• Poor sanitation conditions

2. Long-Term Use of NSAIDs

Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce pain and inflammation but also reduce the stomach's protective mucus.

Common examples include:

• Ibuprofen
• Naproxen
• Aspirin

Taking these regularly—especially without food—raises your risk of a stomach ulcer.

---

Other Risk Factors

While H. pylori and NSAIDs are the main causes, other factors can increase your risk:

• Smoking
• Heavy alcohol use
• Long-term steroid use
• Severe physical stress (major illness, burns, surgery)
• Age over 60
• Previous history of ulcers

Rarely, tumors that increase acid production (such as Zollinger-Ellison syndrome) can cause recurrent ulcers.

Symptoms of a Stomach Ulcer

The most common symptom is burning stomach pain.

This pain:

• Is usually located in the upper middle abdomen
• May feel worse between meals or at night
• Can improve temporarily after eating or taking antacids
• May come and go

Other symptoms can include:

• Bloating
• Nausea
• Vomiting
• Early fullness when eating
• Unexplained weight loss

Warning Signs (Seek Immediate Medical Care)

A stomach ulcer can bleed or perforate (tear through the stomach wall). These are medical emergencies.

Call a doctor immediately or go to the ER if you experience:

• Vomiting blood (bright red or coffee-ground appearance)
• Black, tarry stools
• Severe, sudden abdominal pain
• Dizziness or fainting
• Rapid heartbeat

These signs may indicate internal bleeding.

How Doctors Diagnose a Stomach Ulcer

If your symptoms suggest a stomach ulcer, your doctor may recommend:

1. Testing for H. pylori

This can be done with:

• Breath test
• Stool test
• Blood test
• Biopsy during endoscopy

2. Endoscopy

A thin tube with a camera is inserted through the mouth to look at the stomach lining. This is the most accurate way to confirm a stomach ulcer.

Doctors may also take a biopsy to rule out stomach cancer, especially in patients over 60 or those with concerning symptoms.

3. Imaging

In some cases, imaging tests may be used if complications are suspected.

Medical Treatment for a Stomach Ulcer

The good news: most stomach ulcers heal with proper treatment.

If Caused by H. pylori

Treatment typically includes:

• Two antibiotics
• A proton pump inhibitor (PPI) to reduce stomach acid

This combination is taken for 10–14 days. It's critical to complete the full course, even if symptoms improve.

If Caused by NSAIDs

Your doctor may:

• Stop the NSAID
• Lower the dose
• Switch to a different medication
• Prescribe a PPI

Common acid-reducing medications include:

• Omeprazole
• Pantoprazole
• Esomeprazole

These allow the stomach lining to heal by reducing acid production.

Healing Timeline

Most stomach ulcers heal within:

• 4–8 weeks with proper treatment

Follow-up testing may be required to ensure healing, especially if the ulcer was large or bleeding.

---

Lifestyle Changes That Support Healing

Medical treatment is essential, but lifestyle changes can help prevent recurrence.

Consider:

• Stopping smoking
• Limiting alcohol
• Avoiding NSAIDs unless medically necessary
• Eating balanced meals
• Managing stress

Contrary to popular belief, spicy food alone does not cause stomach ulcers—but it can irritate an existing one.

---

What Happens If You Ignore a Stomach Ulcer?

Ignoring symptoms can lead to:

• Internal bleeding
• Perforation (a hole in the stomach wall)
• Infection of the abdominal cavity
• Gastric outlet obstruction (food can't leave the stomach)

These complications can be life-threatening.

This is why ongoing burning pain should never be dismissed as "just indigestion" without evaluation.

---

Is It Really a Stomach Ulcer?

Other conditions can mimic ulcer symptoms, including:

• Acid reflux (GERD)
• Gastritis
• Gallbladder disease
• Pancreatitis
• Functional dyspepsia

In some cases, persistent ulcer-like symptoms could signal stomach cancer, particularly in older adults. This is uncommon but serious.

If your pain:

• Lasts more than a few days
• Keeps coming back
• Worsens over time
• Is paired with weight loss or fatigue

You should speak to a doctor.

---

When to Speak to a Doctor

You should schedule a medical appointment if you have:

• Ongoing upper abdominal burning
• Frequent need for antacids
• Pain that wakes you at night
• Risk factors like NSAID use or smoking

Seek urgent medical care if you notice any signs of bleeding or severe pain.

A stomach ulcer is treatable—but only if properly diagnosed.

Final Thoughts

A constant burning sensation in your upper abdomen could be your body signaling a stomach ulcer. Most ulcers are caused by H. pylori infection or long-term NSAID use, and most heal with medication.

But ulcers can become dangerous if ignored.

Pay attention to persistent symptoms. If you're unsure what's causing your discomfort, try using a free AI-powered symptom checker to help you understand your symptoms better, and most importantly, speak to a doctor about any symptoms that concern you—especially if they could be serious or life-threatening.

Your stomach lining can heal. The key is timely care.
