Lactose Intolerance Breath Test
SKU:IBTL
Bloating, abdominal pain, diarrhoea, and excessive gas after consuming milk or dairy products may signal lactose intolerance. The Lactose Intolerance Breath Test measures hydrogen and methane levels in the breath after lactose ingestion, helping to identify whether the body struggles to digest milk sugar effectively.
Why Lactose Intolerance Breath Test Matters?
Lactose intolerance is one of the most common digestive conditions, caused by reduced levels of the enzyme lactase. Undiagnosed intolerance can lead to ongoing discomfort, poor nutrient absorption, and unnecessary dietary restrictions. This test provides clear evidence, guiding you toward the right nutritional adjustments for better digestive health.
What Gets Assessed?
- Breath hydrogen and methane levels
- Digestive response to lactose ingestion
- Signs of lactose malabsorption and fermentation
