Diagnosis and Treatment

Your doctor may have you take a breath test to determine if you have an H. pylori infection. You will be given a substance to swallow, and then you will wait a few minutes. Your doctor will then measure your breath for the bacteria by having you blow up a balloon. If the test is positive for H. pylori, your doctor may choose to treat you with antibiotics for 2-3 weeks.
