question: Hello doctor, I am a 47-year-old male. I have chronic fatigue being on healthy diet. I am not on any medication. There is also low libido. In the blood test report, the levels of UIBC, DHEA, estradiol, vitamin D, progesterone, phosphorus, and platelets were low from the normal level and high B12 level. In the past, my blood test has shown low RBC. Can you tell me what is going on?
