HYDROGEN BREATH TEST Meaning and
Definition
-
The hydrogen breath test is a diagnostic medical procedure designed to measure the production of hydrogen gas in the digestive system. It is a non-invasive test that helps to identify certain conditions that may be affecting the gastrointestinal tract, particularly those related to the malabsorption of carbohydrates.
During the test, the patient is given a controlled amount of a carbohydrate substance usually in the form of lactose, fructose, or sorbitol. These substances are not completely absorbed by the small intestine in some individuals, leading to their fermentation by bacteria in the large intestine. This fermentation process generates hydrogen gas as a byproduct.
The patient's breath is collected and analyzed at regular intervals for the presence of hydrogen gas using a specialized machine. Elevated levels of hydrogen gas in the breath indicate that the carbohydrate ingested was not fully absorbed and reached the large intestine, where it was fermented.
The hydrogen breath test is commonly used to diagnose conditions such as lactose intolerance, fructose malabsorption, and small intestinal bacterial overgrowth (SIBO). Based on the test results, healthcare professionals can determine if specific dietary modifications or further medical interventions are necessary to alleviate symptoms and enhance digestive health.
Overall, the hydrogen breath test provides valuable insights into the digestive processes and helps guide appropriate management strategies for individuals with carbohydrate malabsorption disorders.
