Intestinal Permeability Assessment is a powerful noninvasive gastrointestinal test assessment of small intestinal absorption and barrier function in the bowel. The small intestine uniquely functions as a digestive/absorptive organ for nutrients as well as a powerful immune and mechanical barrier against excessive absorption of bacteria, food antigens, and other macromolecules. Both malabsorption and increased intestinal permeability ("leaky gut") are associated with chronic gastrointestinal imbalances as well as many systemic disorders.

Increased intestinal permeability (leaky gut) of the small intestine can:

Increase the number of foreign compounds entering the bloodstream
Allow bacterial antigens capable of cross-reacting with host tissue to enter the bloodstream, leading to auto-immune processes
Enhance the uptake of toxic compounds that can overwhelm the hepatic detoxification system and lead to an overly sensitized immune system

Leaky gut has been observed in a range of disorders such as:

Inflammatory Bowel Disease (IBD)
Food allergy
Inflammatory joint disease
Chronic dermatologic conditions

Studies have demonstrated that increased intestinal permeability can contribute symptoms in patients with ankylosing spondylitis, fibromyalgia, chronic fatigue, chemical sensitivities, food allergies, yeast overgrowth, chronic pain, food allergies, and rheumatoid arthritis.

Decreased permeability can cause malabsorption, subsequent malnutrition, and failure to thrive. In certain disease states of the small intestine, such as gluten-sensitive enteropathy, permeability to large molecules may increase while permeability to small molecules decreases - a result of damage to the microvilli. As a result, nutrients become even less available to assist in the detoxification of antigens flooding the system.

Possible causes of increased intestinal permeability (leaky gut) include:

Intestinal infection
Ingestion of allergenic foods or toxic chemicals
Deficient secretory IgA
Trauma and endotoxemia
NSAIDs
Yeast overgrowth

The Intestinal Permeability Assessment gastrointestinal test directly measures the ability of two non-metabolized sugar molecules to permeate the intestinal mucosa. The patient drinks a premeasured amount of lactulose and mannitol. The degree of intestinal permeability or malabsorption is reflected in the levels of the two sugars recovered in a urine sample collected over the next 6 hours.
