Bacterial overgrowth syndrome is a malabsorption disorder. Under normal conditions, the proximal small bowel contains < 105 bacteria/mL, mainly gram-positive aerobic bacteria. This low bacterial count is maintained by normal peristalsis, normal gastric acid secretion, mucus, secretory IgA, and an intact ileocecal valve.
In some patients with short bowel syndrome, bacterial overgrowth can, to some extent, paradoxically exert a favourable effect on the macro-organism. Bacteria may partly metabolise saccharides and thus form some further energy substrates more easily utilisable by a diseased human.
