I know for sure I have pretty bad iron deficiency anemia but now I’m starting to wonder if I need to worry about my B-12s, vitamin D and folate levels. I have severe fatigue, stiff joints and back pains, I get build up in my legs, my memory is pretty bad, I get lightheaded, I’m pale, no appetite and I’m losing weight, depressed. I’m only 20 years old, 100 pounds. So I don’t know what type of anemia it could be. Do you have any suggestions for me?
