Final answer:
A high level of H2 in the breath after consuming lactose can indicate lactose intolerance. The hydrogen breath test, intestinal biopsy, and stool acidity test for infants are available diagnostics. Lactose-free products and supplements containing lactase aid in lactose digestion.
Step-by-step explanation:
The level of H2 (hydrogen) in a breath test that suggests lactose intolerance is higher than that found in lactose-tolerant individuals. During a hydrogen breath test, if lactose is not properly digested, it is fermented by bacteria in the colon, leading to the production of hydrogen. This hydrogen is then absorbed into the bloodstream and exhaled in the breath. Elevated levels of hydrogen in the breath after consuming lactose can confirm lactose intolerance.
There are diagnostic methods available to identify this condition, including the hydrogen breath test, intestinal biopsy, and stool acidity test for infants. In the case of adults, a level of hydrogen exceeding 20 parts per million over the baseline in multiple breath samples taken after ingestion of lactose can indicate lactose intolerance. However, it's important to consult with a healthcare provider for an accurate diagnosis and management of the condition.
For those diagnosed with lactose intolerance, there are lactose-free dairy products and dietary supplements containing lactase available, which can aid in the digestion of lactose when taken with food.
