Final answer:
Long-term ulcers can be caused by NSAIDs, alcohol, smoking, or stress, which damage the stomach lining and allow acid to cause ulcers.
Step-by-step explanation:
Physical or chemical trauma can lead to the development of long-term ulcers in the stomach lining. Factors such as excessive alcohol consumption, smoking, and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) can damage the stomach's mucosal barrier.
This disruption can cause the acidic gastric juice to erode the stomach tissue, leading to ulcers. Stress is another factor that can increase stomach acid production, potentially contributing to ulcer formation. However, the most common cause of peptic ulcers is an infection with Helicobacter pylori.
A bacterium able to survive in the stomach's harsh acidic environment. It is important to address these ulcers with appropriate medical intervention, including antibiotics to eradicate H. pylori and medications that inhibit acid production, which facilitate the healing of the ulcer.
