Impaired accuracy of the dexamethasone suppression test after bariatric surgery: implications for post-surgical cortisol interpretation
Post-BS subjects showed higher post-DST cortisol levels and reached lower plasma dexamethasone concentration compared to non-operated individuals, which may lead to false-positive results. These findings highlight the need to consider dexamethasone measurements to enhance DST interpretation in post-BS patients. Further studies are necessary to validate these findings in broader populations. The underlying mechanisms need to be explored.
