When obtaining the history of patients with Helicobacter pylori infection, one should pay particular attention to anorexia and weight loss, pallor or laboratory findings of anemia, vomiting, abdominal pain associated with meals or nighttime, and any description of GI bleeding. A history of such findings raises the concern of peptic ulcer disease (PUD).

In the child in whom H pylori infection is suspected, the history should include the following:

  • Character, location, frequency, duration, severity, and exacerbating and alleviating factors of abdominal pain

  • Bowel habits and description of stool

  • Appetite, diet, and weight changes

  • Halitosis, vomiting, and description of gastric material

  • Family history of ulcer disease or GI conditions (eg, Crohn disease)

  • Medications (prescribed and over the counter)

  • Previous diagnostic testing and specific therapy in the GI tract
