Anemia in gastric cancer appears as a consequence of vitamin B12 deficiency, since this element plays a huge role in the formation of body cells and the epithelial layer of the gastrointestinal tract. Today, the incidence of this disease has increased, so taking care of your own health does not hurt.
Anemia with a disease such as stomach cancer is characterized by an insufficient amount of iron in the human body. There is a decrease in the level of iron and iron-containing proteins in the blood plasma, as a result of which the concentration of erythrocytes in the blood decreases. In addition, their shape and magnitude undergo changes, the color index worsens, which says that red blood cells have a deficiency of hemoglobin.
