Peptic ulcers include gastric ulcers, duodenal bulb ulcers, complex ulcers, and more. The primary cause is usually Helicobacter pylori infection, particularly in patients with duodenal bulb ulcers. Generally, eradicating Helicobacter pylori can cure the ulcer. However, a small number of patients, due to underlying diseases or irregular medication use, often develop resistance to Helicobacter pylori. In such cases, peptic ulcers are prone to recurrent flares. Additionally, peptic ulcers caused by other factors, such as smoking and alcohol stimulation, poor dietary habits, medication, emotional issues, etc., can generally be cured by removing the triggers. However, it's essential to develop good dietary and living habits and strictly follow medical advice regarding medications.
