Anemia: Symptoms, Treatment and Causes
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Iron is a mineral our bodies need. Iron deficiency is a condition resulting from not enough iron in the body. It is the most common nutritional deficiency and the leading cause in the US. Iron deficiency is caused due to increased iron deficiency from diseases, nutritional deficiency, or blood loss and the body's inability to intake or absorb iron. Children, teen girls, pregnant women, and babies are at most risk for developing iron deficiency. Symptoms of iron deficiency include feeling weak and tired, decreased work or school performance, slow social development, difficulty maintaining body temperature, decreased immune function, and an inflamed tongue. Blood tests can confirm an iron deficiency in an individual. Treatment depends on the cause of the deficiency. Proper diet that includes recommended daily allowances of iron may prevent some cases of iron deficiency.
