Certain conditions, such adrenal insufficiency (called Addison’s disease), can prevent your adrenal glands from making enough hormones. Addison’s disease is a rare but serious disease. The symptoms of Addison’s disease include fatigue, body aches, unexplained weight loss, low blood pressure, lightheadedness, loss of body hair and skin discolouration. Addison’s disease is recognised by doctors and can be detected through blood tests that show insufficient hormone levels. On the other hand, these tests are often normal in people who are told they have adrenal fatigue.
