Nutrition Deficiency
Nutrition deficiency is one of the most common causes of anemia. A lack of essential vitamins and minerals, such as iron, folate, and vitamin B12, can lead to anemia. Iron deficiency is the most common type of anemia. It occurs when your body is not getting enough iron from your diet or is unable to absorb the iron it gets. Iron is needed to make hemoglobin, a protein in red blood cells that carries oxygen to all parts of your body.
Blood Loss
Blood loss is another potential cause of anemia. This can occur due to acute traumatic events, such as surgery or an injury. In women, menorrhagia, or heavy menstrual bleeding, can cause anemia. Blood loss can also be caused by slow, chronic health conditions, such as gastrointestinal bleeding or a bleeding ulcer.
Destruction of Red Blood Cells
The destruction of red blood cells can also lead to anemia. This can occur due to a variety of conditions, including autoimmune disorders, certain medications, and infections. In some cases, red blood cells may be destroyed by the body's own immune system. In other cases, red blood cells may be destroyed by a virus or bacteria.
