Hydrogen Breath Test
The Hydrogen Breath Test is a medical procedure used to diagnose several conditions related to the digestive system. It measures the amount of hydrogen in a person's breath, which can indicate problems such as lactose intolerance, fructose intolerance, and bacterial overgrowth in the small intestine.
Procedure[edit]
The Hydrogen Breath Test begins with the patient fasting for at least 12 hours. The patient then blows into a bag to provide a baseline breath sample. After this, the patient consumes a solution containing a known amount of lactose, fructose, or glucose. Breath samples are then collected at regular intervals, typically every 15 to 30 minutes, for a few hours.
Interpretation[edit]
The breath samples are analyzed for hydrogen content. A significant increase in breath hydrogen may indicate that the patient is unable to properly digest the sugar in the solution, suggesting a diagnosis of lactose or fructose intolerance. Alternatively, an early increase in breath hydrogen may suggest bacterial overgrowth in the small intestine.
Risks and Complications[edit]
The Hydrogen Breath Test is generally safe, with few risks or complications. Some patients may experience bloating, diarrhea, or other symptoms of indigestion during the test.
