Anemia is characterized by a decrease in hemoglobin concentration or the capacity to carry oxygen in the blood. Hemoglobin is the molecule that transports oxygen from the lungs to all body cells.

Hemoglobin deficiency may be due to a decreased number of red blood cells, also called red blood cell, blood volume or a reduction of hemoglobin content within them.

Red blood cells live approximately 100 days and is in the bone marrow where they are constantly producing new ones. To this end, the bone needs certain nutrients like iron, folic acid, vitamin B12 and protein among others.

Different types of anemias are classified according to their etiologic basis, ie the cause that provokes it.

The anemia caused by inadequate intake of nutrients involved in erythropoiesis are often called nutritional, although its appearance can also be related to a suboptimal use of these nutrients.

The symptoms coincide in most cases of anemia: fatigue, fatigue, weakness, irritability, pallor, anorexia or loss of appetite, nausea, diarrhea, mouth sores and hair loss, etc. The onset is usually insidious.

The skin, mucous membranes and nails are pale by the decrease of circulating hemoglobin. If anemia is long standing can be found atrophy of the taste buds of the tongue and other changes more pronounced.
