Gastric ulcer vs duodenal ulcer?

how do you differentiate peptic ulcer disease on whether the location of the lesion is gastric or duodenal in terms of patient history and physical exam findings, which one is aggravated by meals and which one is relieved by meals?

Symptoms of peptic ulcers may vary greatly from person to person. Children and the elderly tend to have symptoms that do not follow the usual patterns or no symptoms at all. Patients who are very ill or taking corticosteroids may have less intense symptoms. When symptoms are absent, peptic ulcers may only be discovered when complications, which can be potentially life-threatening, arise. However, most peptic ulcers are cured without the development of complications.

The most common symptom of peptic ulcers is pain just below the breastbone. It is usually a steady, burning or gnawing sore pain or dull pain. It generally only lasts for minutes but may wake the patient up at night. The pain often occurs once or a few times daily, typically two to three hours after eating and usually lasts for one to several weeks. In some cases, pain may disappear and recur. Drinking or eating generally relieves the pain briefly because it helps buffer the stomach acid. However, it may actually make the pain worse over time.

Gastric ulcers, if I remember correctly are aggravated by intake of food within 30 min to 1 hour of ingestion. Gosh, that is the most I can give you. But I am 99% positive on that.
