At the beginning of the nineteenth century, anemia referred to the pallor of the skin and mucous membranes. After medical science advanced, blood cell counts could be done. Anemia became the disease we know today. Symptoms of Anemia Mild anemia may have no outer symptoms. Weakness, fatigue, and pallor are very common symptom.

Laboratory tests can test both the numbers of red blood cells as well as look at their appearance. Treatments of Anemia Because there are so many different types of anemia as well as causes, treatments vary widely. If the type of anemia results from a vitamin deficiency and there is no underlying cause, treatment is simple. Vitamin supplements can be taken or a change in diet can be made.
