10 Lousy Reasons not to give blood

The red blood cells in our blood are carriers of oxygen and carbon dioxide to and from the different organs of our body. The hemoglobin in the cell is the agent that carries Oxygen. When red blood cells in our blood decrease, our blood can’t carry enough oxygen to various parts of our body. That would make us feel weak and tired, our heart beat to quicken, and our breathing to become fast and shallow. Our blood contains anywhere between five to nine million white blood cells. Each white blood cell has a nucleus and is capable of changing its shape.

The white blood cells in our blood increase greatly in number during an infection, when cancerous cells are formed in our body, or when we’re injured or stressed. The white blood cell count could be caused by weakening of the bone marrow, serious infections, malnutrition, or some immunity–related problem. We need approximately 12 mg of hemoglobin for every 100cc of blood for a man, and about 11 mg of it for a woman. People who have less than that level are considered anemic. Abnormal bleeding, malnutrition, genetically inherited conditions, illnesses, malfunctioning of blood–forming organs or side–effects of medication are all possible causes of anemia. Iron is an important mineral, especially for women. It helps us feel energized besides giving us a “Rosy” complexion. It also affects our growth and boosts our immune system.

Our body needs iron to make hemoglobin and red blood cells. It also needs it to carry oxygen and burn up energy. Anybody could suffer from anemia when they bleed excessively, have indigestion problems, suffer from external injuries and as a result of major surgery. One of the most common causes of iron–deficiency related anemia is lack of hemoglobin. This is, in turn, caused by diet. Common symptoms include dizziness and headaches.
