What diseases can cause anemia?

Many people have symptoms of anemia, but what disease can cause anemia? We need to understand this in detail. The problem of anemia can seriously affect our normal life, especially children with anemia will suffer from anorexia. There are many different groups of people in life, and if they suffer from anemia, it will have a certain impact on the body. Some diseases can also cause anemia. We need to treat these diseases in time to avoid the occurrence of anemia, and we also need to pay attention to preventing the occurrence of some diseases.

1. Hematopoietic anemia (decreased red blood cell production)

(I) Hemoglobin synthesis disorder

1. Iron deficiency anemia: insufficient iron intake, relatively increased iron requirements (pregnancy, children's growth and development period), iron absorption disorders (chronic gastrointestinal diseases, after subtotal gastrectomy), and chronic blood loss.

2. Sideroblastic anemia.

3. Vitamin B6 reactive anemia.

4. Posferrin deficiency anemia.

2. Nuclear maturation disorder

1. Pernicious anemia.

2. Other reasons cause folic acid and/or vitamin Bl2. Megaloblastic anemia caused by deficiency and utilization disorders: malnutrition (food deficiency, improper infant feeding, long-term alcoholism, intractable anorexia), increased requirements (pregnancy, lactation, children's growth and development period, infection with Diphyllobothrium latum, hemolysis, infection, hyperthyroidism, etc.), malabsorption (after total or subtotal gastrectomy, chronic atrophic gastritis, gastric cancer, chronic liver disease, chronic enteritis, malabsorption syndrome, after intestinal resection, bacterial infection of intestinal diverticula), and the effects of drugs on nucleic acid metabolism (such as antifolates, anticonvulsants, antituberculosis drugs, oral contraceptives, neomycin, nitrites, etc.).

(III) Decreased bone marrow hematopoietic function

1. Stem cell defects

(1) Aplastic anemia.

(2) Congenital aplastic anemia.

(3) Pure red cell aplasia.

(4) Myelodysproliferative syndrome.

2. The bone marrow hematopoietic tissue is squeezed out by other cells, causing leukemia, malignant lymphoma, multiple myeloma, bone marrow metastatic cancer, myelofibrosis, systemic mastocytosis, marble bone disease, etc.

3. Erythropoiesis regulatory factor deficiency, renal anemia, endocrine gland (such as pituitary, thyroid) dysfunction, infectious anemia, etc.

The above content is about some situations that may cause anemia. We need to pay attention to our eating habits in our daily lives. Good living habits are very important and can prevent the occurrence of many other adverse diseases. Therefore, we cannot underestimate the consequences of anemia and must prevent the occurrence of anemia in time. If there are friends with anemia around us, they must also be treated in time.
