Peptic ulcers are open sores that develop on the lining of the stomach, upper small intestine, or esophagus. These ulcers can lead to burning pain, discomfort, nausea, bloating, and even bleeding if left untreated. While many people assume that stress or spicy food is to blame, the real culprits behind peptic ulcers are far more complex and, in many cases, treatable. Understanding what causes peptic ulcers is essential for early detection and effective management.
One of the most common causes of peptic ulcers is an infection with Helicobacter pylori (H. pylori), a spiral-shaped bacterium that lives in the digestive tract. This bacterium can weaken the protective mucus lining of the stomach and small intestine, making it easier for stomach acid to damage the tissue beneath. Not everyone infected with H. pylori will develop ulcers, but it significantly increases the risk. The bacteria can spread through contaminated food, water, or close contact with an infected individual.
The second leading cause of peptic ulcers is the frequent use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen. These medications are commonly used for pain relief, inflammation, and fever, but prolonged use can irritate or damage the stomach lining. NSAIDs reduce the production of prostaglandins, substances that help maintain the protective mucus barrier. With reduced protection, stomach acid can create painful ulcers. Individuals who take NSAIDs regularly, especially older adults or those with other health conditions, are at a higher risk.
Although less common, other factors may contribute to ulcer formation. Excess stomach acid production, a condition known as Zollinger-Ellison syndrome, can overwhelm the digestive lining and result in ulcers. This rare disorder involves tumors that cause the stomach to produce excessive amounts of acid. Additionally, lifestyle choices such as smoking, heavy alcohol use, and chronic stress can exacerbate the effects of other risk factors. These habits may not directly cause ulcers, but they can slow healing and increase the likelihood of complications.
A widespread misconception is that spicy foods or emotional stress alone are responsible for ulcers. While these factors can aggravate symptoms, they are not usually the primary cause. It's more accurate to say that they may worsen an existing ulcer rather than create one from scratch. That’s why it’s crucial to seek medical evaluation rather than self-diagnose based on assumptions.
To determine what causes peptic ulcers in an individual case, doctors typically conduct several diagnostic tests. These may include blood tests, stool tests, urea breath tests for detecting H. pylori, or an upper endoscopy to directly visualize the ulcers and collect tissue samples. Knowing the exact cause helps tailor the most effective treatment plan. For example, if H. pylori is found, antibiotics are prescribed along with acid-reducing medications. If NSAIDs are to blame, the patient may need to switch medications and take protective drugs to reduce acid production.
Treatment focuses on healing the ulcer and preventing recurrence. This often includes a combination of antibiotics, proton pump inhibitors (PPIs), and lifestyle modifications. Patients are typically advised to avoid smoking, limit alcohol intake, manage stress levels, and avoid unnecessary NSAID use. In most cases, peptic ulcers heal within a few weeks of starting treatment, although follow-up care is important to confirm full recovery and to monitor for recurrence.
Knowing what causes peptic ulcers allows patients to take proactive steps to protect their digestive health. Preventive strategies include using pain relievers cautiously, avoiding self-medication, and seeking medical advice when experiencing symptoms like stomach pain, indigestion, or unexplained weight loss. Regular medical checkups can help identify early signs of ulcers and reduce the risk of complications like bleeding or perforation.
In rare cases, ulcers can lead to emergency situations if not addressed promptly. Severe pain, vomiting blood, black stools, or sudden abdominal distress may indicate a bleeding or perforated ulcer and require immediate attention. That’s why even mild or recurring symptoms should never be ignored.
Ultimately, understanding the root causes of peptic ulcers empowers individuals to make informed health choices. Whether it’s recognizing the role of H. pylori, being cautious with NSAIDs, or improving lifestyle habits, awareness is key to both treatment and prevention. If you or a loved one is experiencing symptoms, don’t hesitate to consult a gastroenterologist. With the right diagnosis and a personalized care plan, ulcers can be effectively treated, and long-term digestive health can be restored.
