Objectives: Variations of gut microbiota composition have been described in patients with different thyroid disorders. The site of oral levothyroxine (T4) absorption is represented by the small intestine and it has been demonstrated that some bacterial strains possess enzymatic activity that may affect iodothyronine deconjugation, process probably involved in thyroid hormone enterohepatic recycling. The relationship between gut microflora composition and oral T4 requirement ha...
