Abstract
Gut dysbiotic symptoms with a characteristic clinical pattern have been known for many years. In the 1970s Truss advanced the theory that the syndrome is caused by Candida albicans. This has generated much medical controversy. In some centres the attribution has caused rejection of the syndrome itself. A number of studies have demonstrated organic changes in sufferers of what the author prefers to call fungal‐type dysbiosis; however, over the past twenty years convincing data have not been published identifying causal yeasts. There is a further problem with a name involving Candida in that it may cause confusion with established syndromes known to be associated with that organism. This paper will review the literature and advance an alternative hypothesis that the syndrome could have a bacterial rather than a yeast cause.
