This systematic review shows thyroid hormone changes after bariatric surgery, suggesting a need for optimized patient care.
Bariatric surgery leads to significant reductions in TSH and FT3 levels at 6-month and 1-year follow-ups, with no significant change in FT4 level. Further studies are needed to explore the mechanisms of thyroid changes after bariatric surgery and develop strategies to optimize thyroid health in these patients.
