If we feel tired, very fast heart rate and irregular, and breathing the hunt but short, maybe it’s a sign we’re suffering from anemia. Anemia often arise due to various factors.
Anemia is a lack of blood disease, which is characterized by levels of hemoglobin (Hb) and red blood cells (erythrocytes) is lower than normal. If the hemoglobin level is less than 14 g / dl and erythrocyte less than 41% in men, then a man is said to be anemic. Similarly in women, women with hemoglobin levels less than 12 g / dl and erythrocyte less than 37%, then the woman was said to be anemic.
Anemia is generally caused by chronic bleeding. Poor nutrition or impaired absorption of nutrients by the intestine can also cause a person to experience a shortage of blood. Similarly, in pregnant or lactating women, if iron intake is reduced, it is likely to happen anemia. Bleeding in the digestive tract, leakage in the kidneys filter blood, excessive menstruation, as well as blood donors are not balanced with good nutrition can have a risk of anemia.
Acute bleeding also can cause lack of blood. In the event of severe bleeding, anemia symptoms may not appear. Blood transfusion is a major response actions in the event of acute hemorrhage. Bleeding is usually not aware of. Extravasation usually proceeds gradually and in a long time.
Minerals iron, vitamin B12, and folic acid is an essential nutrient in the formation of blood cells. Three elements deficiency can cause anemia. Anemia due to iron deficiency is characterized by a change in the skin. The skin looks pale and dull. In addition, the gland damage occurs continuously, like a smooth tongue, lips and the corners of the mouth are cracked and appear reddish.
Iron (Fe) is a very important mineral for the body, although it is required in very small amounts (trace minerals). Hemoglobin, which transports oxygen to function throughout the body, containing 60-70% iron. Iron deficiency showed that our body hemoglobin and oxygen deficiency. Iron can be obtained from green vegetables and meat, but the iron contained in vegetables is more easily absorbed than the iron in meat. However, that does not mean we have to eat a lot of meat to meet the need of iron, except in cases of iron deficiency element. Every day our bodies need about 20 mg of iron from food. But from that number, only about 2 mg are absorbed by the body and the rest will be disposed of with feces. Iron in our body ranges from 2-4 g, or about 50 mg per kilogram of body weight in the adult male. Whereas in women only 35 mg per kilogram in weight. Generally accompanied by iron deficiency folic acid deficiency.
The body needs vitamin B12 as important as the mineral iron. Vitamin B12 with iron will serve as a precursor of red blood cells. Even vitamin B12 deficiency anemia not only trigger, but can interfere with the nervous system.
Nutrition is associated with less blood disease. Poor food consumption in folic acid, iron, and vitamin B12 are likely to cause a person to be less blood (anemia). Folic acid can be obtained from meat, green vegetables, and milk. Nutrients including folic acid is easily absorbed by the gut and goes along the digestive tract. But why there are still many cases of anemia due to folic acid deficiency. The problem is at the level of nutrients in the food consumed. Poor nutrition or malnutrition is the main cause.
