Simplified diagram of how<unk>  is diagnosed and treatment(s) determined A diagnosis for<unk>  is based on symptoms, with a possible need for more diagnostic tests. In younger patients (less than 60 years of age) without red flags (e.g., weight loss), it is recommended to test for H. pylori noninvasively, followed by treatment with antibiotics in those who test positively. A negative test warrants discussing additional treatments, like proton pump inhibitors, with your doctor. An upper GI endoscopy may also be recommended. In older patients (60 or older), an endoscopy is often the next step in finding out the cause of newly onset<unk>  regardless of the presence of alarm symptoms. However, for all patients regardless of age, an official diagnosis requires symptoms to have started at least 6 months ago with a frequency of at least once a week over the last 3 months.
