Description: The Lactose Intolerance Breath Test is a gastrointestinal test that detects lactose intolerance, a condition affecting more than 50 million Americans. Proper detection enables effective treatment of lactose maldigestion and malabsorption, to help alleviate chronic symptoms of bloating, gas, diarrhea, and abdominal pain. This gastrointestinal test uses a simple, non-invasive breath hydrogen/methane test.

Lactose intolerance is one of the most common gastrointestinal disorders, affecting hundreds of millions of people worldwide. This condition arises from an enzyme (lactase) deficiency in the gut, either a result of genetics or a temporary irritation of the small intestine. Without adequate amounts of lactase, the digestive system is unable to properly break down and absorb lactose, the main sugar in milk and dairy products. When this happens, unabsorbed lactose is fermented by bacteria in the colon, causing the release of hydrogen and methane gases.
