A hydrogen breath test is a simple noninvasive test that evaluates for bacterial overgrowth in the small intestine. Small intestine bacterial overgrowth can cause symptoms such as bloating, flatulence, abdominal discomfort, and nausea.

This test will require you to drink a solution with sugar. You will then at regular intervals breathe into a machine that will measure hydrogen and methane levels. The physician will interpret the readings. Small intestine bacterial overgrowth can be treated with antibiotics.
