Confirming a diagnosis

In most cases, the doctor may suspect a stomach ulcer just based on the presenting symptoms. However, the symptoms may be related to other digestive issues, which is why the doctor may order additional testing, like an endoscopy, to rule them out. 

Because H. pylori is one of the main causes of of stomach ulcers, the doctor may order a urea breath test, blood work or urine testing to determine whether an active infection is present. If confirmed, it will likely be treated with antibiotics. Read more about how H. pylori is treated and the natural options available.

Risk factors

Stomach ulcers are most commonly noted in people with an active H. pylori infection, as well as in people who chronically take anti-inflammatories. Ulcers can also appear in people who are under stress, who consume high amounts of fatty foods, and who drink or smoke excessively. 

Some patients may hae a genetic mutation that favors the appearance of gastritis and ulcers, however. These patients will usually have a positive family history of stomach ulcers.
