In suspected peptic ulcer disease where H. pylori involvement is possible, the first step is to determine whether H. pylori infection is present. Identifying and then eradicating the infection directly targets a common cause of ulcers, improves healing, reduces recurrence, and lowers the risk of complications such as bleeding. Non-invasive tests—in most settings a urea breath test or a stool antigen test—allow you to confirm infection without immediately resorting to invasive procedures. If the test is positive, start eradication therapy tailored to local antibiotic resistance patterns (typically a PPI plus two antibiotics). If the test is negative, you can pursue alternative causes and reserve endoscopy for situations with alarm features or persistent symptoms.

Endoscopy for everyone is not needed as an initial step because it is invasive and not necessary in uncomplicated cases. Empiric PPI without testing may miss an H. pylori infection and can contribute to ongoing ulcers or recurrence if H. pylori is present. CT scanning isn’t used to diagnose peptic ulcers. Test-and-treat for H. pylori, when positive, is the most direct and effective initial approach.
