Causes & Risk Factors
Causes
Blood consists of plasma and cells. There are three types of blood cells:
• White blood cells (leukocytes). These blood cells are useful for fighting infections.
• Platelets / platelets. These blood cells help blood coagulate when injured.
• White blood cells (erythrocytes). These red blood cells carry oxygen from the lungs through the bloodstream to the brain and other tissues and organs. The body requires a supply of oxygen to function. Red blood cells contain hemoglobin which is a protein with iron kayak that gives the red color.
• Platelets / platelets. These blood cells help blood coagulate when injured.
• White blood cells (erythrocytes). These red blood cells carry oxygen from the lungs through the bloodstream to the brain and other tissues and organs. The body requires a supply of oxygen to function. Red blood cells contain hemoglobin which is a protein with iron kayak that gives the red color.
Lots of blood cells produced by the bone marrow. In order to produce red blood cells and hemoglobin, your body needs iron, minerals, protein and other vitamins from the foods you eat.
Common causes of anemia
Anemia occurs when the body produces too few red blood cells, loses too many red blood cells or red blood cells more lethal than replace it. Some types of anemia and their causes are:
• Iron deficiency anemia. The cause of this type of anemia is iron deficiency in the body. The bone marrow needs iron to make hemoglobin. Without enough iron, your body will not produce enough hemoglobin for red blood cells.
• Vitamin deficiency anemia. In addition to iron, the body also requires folate and vitamin B-12 to produce enough red blood cells. Low intake of these substances and other essential nutrients can cause a decrease in red blood cell production. In addition, some people can not effectively absorb vitamin B-12.
• Anemia of chronic disease. Certain chronic diseases, such as cancer and HIV / AIDS. Can affect the production of red blood cells, resulting in chronic anemia. Kidney failure can also cause anemia.
• Aplastic anemia. This species is very rare and is a life-threatening condition. This is caused by the reduced ability of the bone marrow to produce all three types of blood cells. The cause is not known.
• Anemia associated with bone marrow disease. Conditions such as leukemia and myelodysplasia can lead to anemia which causes the production of blood in the spinal cord is reduced.
• Hemolytic anemias. It occurs when the red blood cells were destroyed more rapidly and the spinal cord are not able to compensate by producing red blood cell substitute. Certain diseases such as blood disorders may be the cause. As well as the body's autoimmune disorders can cause the body to produce antibodies to red blood cells that destroy red blood cells.
• Sickle cell anemia. This type of anemia is caused by a defect form of hemoglobin that makes red blood cells are formed like a crescent. These red blood cells die prematurely and cause chronic conditions lack of red blood cells.
• Anemia others. This type of anemia is different from the others, such as thalassemia and anemia caused by defects of hemoglobin.
Risk factors
Some factors that may increase the chances of anemia include:
• Low intake of nutrients in food.
• Health problems of the small intestine or operations related to the small intestine.
• Menstruation.
• Pregnancy.
• Chronic conditions such as cancer, kidney failure or liver failure.
• Heredity.
• Health problems of the small intestine or operations related to the small intestine.
• Menstruation.
• Pregnancy.
• Chronic conditions such as cancer, kidney failure or liver failure.
• Heredity.
Certain infections such as blood disorders and autoimmune exposed to toxic chemicals, and using some drugs that affect the production of red blood cells and cause anemia.
Another risk is diabetes, alcohol and the person who is the strict vegetarian and less intake of iron or vitamin B-12 in food.
Prevention
Many types of anemia can not be prevented. But you can help prevent iron deficiency anemia and vitamin deficiency anemia with healthy foods that contain:
• Iron. Can be found in meat. Another type is nuts, colored dark green vegetables, dried fruit, and others.
• Folate. Can be found in oranges, bananas, dark green vegetables, nuts, cereal and pasta.
• Vitamin B-12. This vitamin is abundant in meat and dairy.
• Vitamin C. Vitamin C helps the absorption of iron. Foods that contain vitamin C include oranges, melons and berries.
Foods that contain iron is important for those who need such high iron in children, menstruating women and pregnant women. Adequate iron intake is also important for babies, vegetarians and athletes.
