Stomach ulcers are a common digestive condition that affects millions of people worldwide. Understanding the causes of stomach ulcers is essential for early diagnosis, effective treatment, and the prevention of serious complications.

Also known as gastric ulcers, these sores develop in the protective lining of the stomach when stomach acid begins to damage the tissue beneath.

The stomach normally produces strong acid to aid digestion and destroy harmful microorganisms. To protect itself from this acid, the stomach creates a thick mucus barrier.

When this protective layer becomes weakened or damaged, stomach acid can erode the stomach lining and lead to ulcer formation.

Although stomach ulcers are often treatable, untreated ulcers may lead to bleeding, perforation, or obstruction of the digestive tract.

Causes of Stomach Ulcers

The two most common causes of stomach ulcers are infection with Helicobacter pylori (H. pylori) bacteria and prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen.

Here is a detailed explanation of the causes of stomach ulcers.

1. H. pylori Infection

pylori bacteria are responsible for a large proportion of stomach ulcers worldwide. The bacteria weaken the stomach’s protective mucus barrier, allowing acid to damage the underlying tissues and create ulcers.

For many patients, asking what causes stomach ulcers, H. pylori infection is often the primary underlying reason.

2. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

Frequent or long-term use of NSAIDs can interfere with the stomach’s ability to maintain its protective lining. This increases the risk of irritation, inflammation, and ulcer formation.

Common NSAIDs associated with ulcers include:

  • Aspirin
  • Ibuprofen
  • Naproxen
  • Diclofenac

3. Excess Stomach Acid

Another answer to what is the reason of ulcer development is excessive stomach acid production. Conditions that increase acid production may contribute to ulcer formation and worsen existing ulcers.

4. Smoking and Alcohol Consumption

Smoking interferes with the healing process and increases stomach acid production. Excessive alcohol consumption can also irritate the stomach lining and increase susceptibility to ulcers.

5. Stress and Lifestyle Factors

Although stress alone does not directly cause ulcers, chronic stress may worsen symptoms and slow healing. Poor dietary habits and irregular meal patterns may also contribute to digestive discomfort.

Stomach Ulcers and Symptoms

The most common signs and symptoms of stomach ulcer include:

Many patients describe the discomfort as a gnawing, burning, or biting sensation in the upper abdomen.

What Do Ulcers Feel Like in the Stomach?

One of the most common questions patients ask is what do ulcers feel like in the stomach.

Most individuals experience a dull, burning pain between the breastbone and the belly button.

The discomfort may worsen when the stomach is empty and improve temporarily after eating food or taking antacids.

The sensation is often described as:

  • Burning pain
  • Gnawing discomfort
  • Hunger-like pain
  • Pressure or fullness

Sharp episodes of abdominal discomfort

Abdominal Pain and Left Side Pain

Many patients experience abdominal pain and left-sided pain associated with stomach ulcers.

The pain is typically located in the upper abdomen but may sometimes radiate toward the left side of the abdomen or chest, depending on the location and severity of the ulcer.

Severe or sudden pain may indicate a complication, such as bleeding or perforation, and requires immediate medical attention.

Risk Factors for Stomach Ulcers

Several factors increase the likelihood of developing stomach ulcers:

  • pylori infection
  • Long-term NSAID use
  • Smoking
  • Alcohol consumption
  • Advanced age
  • Chronic medical conditions
  • Excess stomach acid production
  • Previous history of ulcers

Diagnosis of Stomach Ulcers

Diagnosing stomach ulcers typically begins with a detailed medical history and physical examination.

Firstly, healthcare providers often ask about the nature of the pain, its location, whether it improves or worsens after eating, and the presence of associated symptoms such as nausea, bloating, weight loss, or black stools.

Understanding how the symptoms have changed over time can help physicians determine whether an ulcer or another digestive condition may be responsible.

Secondly, to identify the underlying cause of the ulcer, doctors frequently perform tests to detect Helicobacter pylori (H. pylori) infection, one of the most common causes of stomach ulcers.

These tests may include a urea breath test, stool antigen test, or blood test. Identifying and treating H. pylori is important to prevent recurrence and promote healing.

If symptoms are severe, persistent, or associated with complications such as bleeding, physicians may recommend an upper gastrointestinal endoscopy.

During this procedure, a thin, flexible tube equipped with a camera is inserted through the mouth to examine the stomach lining and the upper portion of the small intestine.

Endoscopy allows healthcare providers to directly visualize the ulcer and obtain biopsy samples if necessary to rule out other conditions, including stomach cancer.

Additional diagnostic studies may be performed in certain situations.

Moreover, imaging studies and laboratory tests can help evaluate complications such as bleeding, anemia, or perforation.

Early diagnosis allows treatment to begin promptly and significantly reduces the risk of serious complications.

Treatment of Stomach Ulcers

Treatment strategies primarily focus on addressing the underlying cause of the ulcer, reducing stomach acid production, relieving symptoms, and promoting healing of the damaged tissue.

The specific treatment plan often depends on the identified causes of stomach ulcers and the severity of the condition.

When H. pylori infection is responsible for the ulcer, physicians typically prescribe a combination of antibiotics to eliminate the bacteria along with acid-suppressing medications.

This approach not only promotes healing but also reduces the likelihood of the ulcer returning in the future.

To decrease acid production and allow the stomach lining to recover, doctors commonly prescribe proton pump inhibitors (PPIs) or H2 receptor antagonists.

These medications reduce gastric acid secretion and create a more favorable environment for healing.

Antacids and protective medications that coat the stomach lining may also be recommended to provide temporary relief from pain and discomfort.

If nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen are identified as the underlying cause, healthcare providers may advise reducing the dose, discontinuing

the medication, or switching to an alternative pain reliever when appropriate.

Lifestyle modifications also play an important role in recovery. Patients are often encouraged to avoid smoking, limit alcohol consumption, reduce caffeine intake, and avoid foods that worsen symptoms.

Maintaining a balanced diet rich in fruits, vegetables, fiber, probiotics, and vitamin C may further support healing and improve digestive health.

Although most stomach ulcers heal successfully with medical treatment, surgery may occasionally be required for severe complications such as bleeding, perforation, obstruction, or ulcers that fail to respond to conventional therapy.

FAQ’s

What is the reason for ulcer formation in the stomach?

Ulcers develop when stomach acid damages the protective lining of the stomach, usually due to bacterial infection or medication use.

Can stomach ulcers cause left-sided abdominal pain?

Yes. Some individuals experience abdominal pain and left-sided pain depending on the location of the ulcer.

Are stomach ulcers curable?

Yes. Most stomach ulcers heal successfully with appropriate treatment and management of the underlying cause.
