'Great tan but I feel awful'. Diagnosis: Autoimmune primary hypoadrenalism.

'Everyone says I look great but I feel awful. I've lost weight, I feel sick all the time, I don't have any energy and I struggle just to get through the day'. Andrew is lean and tanned, but he has lost 8 kg since his last visit 3 months ago. He seems a bit flat in mood and listless in manner. He doesn't have a temperature, his blood pressure (BP) is 105/65, and examination of his chest and abdomen is normal. When the results of Andrew's tests come back the following day you are surprised to see abnormalities in his electrolytes.
