Can a thyroid function test detect adrenal problems?

A thyroid function test (TFT) does not directly diagnose adrenal problems like adrenal insufficiency or Cushing’s syndrome. However, thyroid and adrenal glands work closely together, and symptoms of thyroid dysfunction can overlap with adrenal issues. If thyroid function appears normal but symptoms like fatigue or weight changes persist, your doctor may order additional tests to assess adrenal function, such as a cortisol test or an ACTH stimulation test. These tests can help evaluate whether the adrenal glands are producing adequate levels of cortisol, a hormone essential for stress response and metabolism.
