Endoscopy provides direct visualization of the stomach lining and confirms the diagnosis of peptic ulcer.Dietary history may yield information suggestive of a peptic ulcer.Blood in the stool indicates a gastrointestinal abnormality,but it does not conclusively confirm a diagnosis of peptic ulcer.An abdominal ultrasound is used to rule out other gastrointestinal alterations such as gallstones,tumor,or mechanical obstruction.
