Evaluation of Leaky Gut Results

The leaky gut breath test utilizes sucrose (table sugar) for detection of gut function. Sucrose is normally broken down by an enzyme called sucrase located in the brush border of the intestines. The brush border normally absorbs all food components. Breakdown of sucrose results in formation of simpler sugars glucose and fructose. These sugars are ultimately processed by the liver to carbon dioxide. Sucrase activity can be assessed by measuring the appearance of carbon dioxide in breath over 90 minutes. If sucrase activity is diminished, the lining of the intestine are damaged. This intestinal damage is described as leaky gut syndrome.

A score between 0 and 50 units indicates normal sucrose absorption. A result greater than 50 suggests leaky gut syndrome. Shown below are examples of normal and leaky gut tests:
