Verified step by step guidance1
Understand that peptic ulcers are sores that develop on the lining of the stomach, small intestine, or esophagus.
Recognize that while high levels of stomach acid can contribute to the development of ulcers, they are not the primary cause.
Identify Helicobacter pylori (H. pylori) as a type of bacteria that can infect the stomach lining and is the primary cause of most peptic ulcers.
Consider that frequent use of antacids is typically a treatment rather than a cause of ulcers, as they help neutralize stomach acid.
Acknowledge that excessive consumption of spicy foods may irritate the stomach lining but is not a primary cause of peptic ulcers.
