Summary
Intestinal absorption of levothyroxine (LT4) tablets depends on its dissolution in gastric
acid secretion, which is reduced after bariatric interventions. Impaired LT4 absorption due
to low gastric dissolution has been reported in patients with atrophic or chronic gastritis.
The objective of this study is to evaluate the absorption of LT4 tablets in morbidly obese
patients before and after Roux-en-Y bariatric surgery.
