Causes of severe anemia, what to eat

The causes of severe anemia are diverse, mainly including blood loss (such as heavy menstruation, gastrointestinal bleeding), rheumatic immune diseases (such as systemic lupus erythematosus), and hematologic disorders (such as aplastic anemia, leukemia). For severe anemia, dietary recommendations include consuming foods rich in iron, such as animal liver, lean meat, and spinach. Additionally, supplementation with folic acid and vitamin C is advised to enhance iron absorption. If dietary intake is insufficient to correct the anemia, medications such as iron supplements, folic acid, and vitamin B12 may be required under a doctor's guidance. Furthermore, treating the underlying cause of anemia is also crucial, such as controlling bleeding and managing the primary disease.
