Dexamethasone Suppression Test

The Dexamethasone Suppression Test helps doctors evaluate how your body produces certain hormones, especially cortisol. You take a small dose of dexamethasone, a synthetic steroid, which should tell your brain to reduce cortisol production if your system is functioning normally. By measuring cortisol levels before and after taking dexamethasone, doctors can determine if your body is overproducing cortisol, which may indicate conditions like Cushing's syndrome. This test helps identify hormonal imbalances and guides appropriate treatment.
