Causes of anemia:
1. Decreased erythropoiesis: abnormal hematopoietic stem and progenitor cells such as leukemia, abnormal hematopoietic regulation of bone marrow such as aplastic anemia, and insufficient hematopoietic substances such as iron deficiency anemia and megaloblastic anemia. If you don't get enough nutrition in your daily life, it may also lead to anemia, which usually happens to people who control their diet too much or are picky eaters.
2. Increased destruction of red blood cells: such as hemolytic anemia.
3. Hemorrhagic anemia: Excessive blood loss may also cause hemorrhagic anemia, usually due to trauma or blood vessel rupture during the onset, thus causing massive bleeding and leading to anemia.
4. Other anemia:
Some anemia diseases that are difficult to treat in life may also cause anemia. More common, such as thalassemia, this type of anemia is generally difficult to treat and generally requires professional treatment to improve the condition.
Preventive measures for anemia:
1. Pay attention to find out the cause of anemia and treat it according to the cause.
2. To supplement iron, eat more iron-rich foods at ordinary times.
3. Eat some foods that help nourish blood, promote blood circulation, benefit qi and strengthen spleen.
