What Causes a Stomach Ulcer?

Stomach ulcers, also known as peptic ulcers, are open sores that develop on the inner lining of the stomach. They can cause significant discomfort and, if left untreated, may lead to serious complications. Understanding what causes stomach ulcers is crucial in preventing and managing this common gastrointestinal condition.

Helicobacter pylori Infection

One of the primary causes of stomach ulcers is an infection with the bacterium Helicobacter pylori (H. pylori). This bacterium can damage the protective lining of the stomach, allowing acid to create an open sore. H. pylori infection is prevalent worldwide and can be acquired through contaminated food, water, or close contact with an infected person.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

Regular use of NSAIDs, such as ibuprofen, aspirin, and naproxen, is another common cause of stomach ulcers. These medications can irritate and erode the stomach lining over time, especially when taken in high doses or for extended periods. People who frequently use NSAIDs for pain relief or anti-inflammatory purposes are at a higher risk of developing ulcers.

Excessive Stomach Acid Production

An overproduction of stomach acid can also lead to ulcers. This condition, known as Zollinger-Ellison syndrome, is rare but results in tumors in the pancreas or duodenum that increase acid production. Excessive acid can overwhelm the stomach’s protective mechanisms, leading to ulcer formation.

Lifestyle Factors

Certain lifestyle factors can contribute to the development of stomach ulcers. These include:

• Smoking: Smoking increases stomach acid production and reduces the stomach’s ability to heal itself.
• Alcohol Consumption: Excessive alcohol intake can irritate and erode the stomach lining, making it more susceptible to ulcers.
• Stress: While stress alone does not cause ulcers, it can exacerbate symptoms and hinder the healing process.
• Diet: Although no specific diet causes ulcers, spicy foods, caffeine, and certain acidic foods can aggravate existing ulcers.

Genetic Predisposition

Genetics may also play a role in ulcer development. Some individuals may be more prone to ulcers due to inherited factors that affect the stomach lining’s ability to resist acid.

Symptoms of Stomach Ulcers

Common symptoms of stomach ulcers include:

• Burning or gnawing pain in the stomach, often between meals or at night
• Bloating and belching
• Heartburn or acid reflux
• Nausea or vomiting
• Weight loss and loss of appetite

In severe cases, ulcers can cause bleeding, leading to black or bloody stools and vomiting blood. If you experience these symptoms, it is essential to seek medical attention promptly.

Treatment and Prevention

Treatment for stomach ulcers typically involves:

• Medications: Antibiotics to treat H. pylori infection, proton pump inhibitors (PPIs), and H2-receptor antagonists to reduce stomach acid, and antacids to neutralize acid.
• Lifestyle Changes: Quitting smoking, reducing alcohol intake, managing stress, and avoiding NSAIDs can help prevent and manage ulcers.

Understanding what causes stomach ulcers is essential for prevention and effective treatment. If you suspect you have a stomach ulcer, consult a healthcare professional for a proper diagnosis and treatment plan.
