A little copy and paste ----- Why prednisone causes fatigue
Prednisone is more powerful than your body’s own cortisol. This means that prednisone will outcompete your own cortisol for receptor sites in tissue.
When you take prednisone over the long term, your body goes through a phenomenon known as feedback inhibition. The extra cortisol from the prednisone tells your body to stop making its own cortisol.
If this continues for many years, the part of your adrenal gland known as the zone fasciculata will shrink. If this occurs, not only will you be profoundly fatigued, you will need glucocorticoid drugs to keep your cortisol levels up. Your body can no longer create its own cortisol.
