ingestion of test‐carbohydrates is used for different diagnostic purposes. There is a lack of …

The concept of small intestinal bacterial overgrowth (SIBO) arose in the context of
maldigestion and malabsorption among patients with obvious risk factors that permitted the …

Most humans, like other mammals, gradually lose the intestinal enzyme lactase after infancy
