ANEMIA may be secondary or primary. A secondary anemia is one in which the blood disorder is the result of a known disease, such as cancer, tuberculosis, rheumatism; or it may result from a serious bleeding, direct loss of blood from haemorrhoids, uterine haemorrhage, and the like. A primary anemia is one in which no cause for the morbid condition of the blood can be defined. There is good reason, however, to believe that the majority of cases of primary anemia are the result of a toxaemia, or an infection having its origin in the gastro-intestinal tract, and in these conditions the diet is a most important factor in treatment. The dietetic treatment of the various forms of secondary anemia calls for little comment here; when the cause has been removed, the blood condition rapidly improves under the influence of rest, fresh air, attention to the bowels, administration of iron and arsenic, with as full and generous a diet as the patient can assimilate. The treatment of the different forms of primary anemia calls for detailed consideration. These may be considered under the following sections: - 380
