I have been experiencing a lot debilitating symptoms but have recieved a diagnosis as of yet. My symptoms are extreme fatigue, lightheaded, difficulty breathing, poor sleep, tingling and poor peripheral circulation, cracks at corners of mouth. I have read about all kinds of nutrient deficiencies and it seems like iron most resembles my symptoms. However my blood count came back "normal". I have not had my serum iron or ferritin checked yet but my B vitamins came out normal. I did go on a near starvationdiet for 3 months, used ephedrine, and lost 60 pounds so I am thinking I depleted some nutrient/s but I am not sure which. I have read that low blood volume can mask anemia since the blood cells would be more concentrated in a sample. Any help is greatly appreciated.
