Causes of Anemia

The causes of anemia are diverse, mainly including the following aspects: 1. Nutritional deficiencies: Lack of essential nutrients for blood production, such as iron, vitamin B12, and folic acid. This is commonly seen in individuals with unbalanced diets or malnutrition. 2. Excessive blood loss: Blood loss caused by trauma, surgery, or gastrointestinal bleeding, leading to a decrease in red blood cell count. 3. Chronic diseases: Conditions such as kidney disease, rheumatic diseases, and cancer can lead to long-term depletion of red blood cells, resulting in anemia. 4. Bone marrow hematopoietic dysfunction: Disorders such as aplastic anemia and leukemia impair the bone marrow's normal ability to produce blood cells, leading to reduced red blood cell production. It is recommended to develop a targeted treatment plan based on individual circumstances to restore health.
