Reasons for low average hemoglobin concentration

Hemoglobin concentration is an item in routine blood tests. It refers to the hemoglobin content of red blood cells in the whole blood. Low hemoglobin is an important basis for diagnosing whether a person has iron deficiency anemia. If you often experience dizziness, fatigue, poor spirits, pale complexion, etc., you need to go to the hospital for a routine blood test to see if the average hemoglobin concentration is low.

1. Iron deficiency anemia: Inadequate iron intake directly affects hemoglobin production, thus leading to major malfunctions in the production of hemoglobin molecules. This will undoubtedly cause low hemoglobin levels.

2. Excessive bleeding: such as hemorrhoids, heavy bleeding during childbirth, dysfunctional uterine bleeding, menorrhagia, etc.

3. Hormone imbalance: Hormone imbalance can also lead to low hemoglobin levels. Sometimes hypothyroidism can cause the body's metabolic rate to slow down, causing the patient to feel tired and drowsy, which is also an important factor.

4. Pernicious anemia: Patients with spleen or pernicious anemia may experience a decrease in hemoglobin levels due to the destruction of too many red blood cells.

5. Renal failure: Renal failure caused by long-term infection, cancer, Crohn's disease and other chronic diseases can also cause a decrease in hemoglobin levels. Other similar causes include intestinal infections and autoimmune diseases (such as systemic lupus erythematosus).

6. Hepatitis B virus infection: The reason for low hemoglobin may also be that hepatitis B virus infection has a certain inhibitory effect on bone marrow hematopoietic function, resulting in obstruction of red blood cell differentiation and maturation. In addition, chronic hepatitis, splenomegaly, and hypersplenism will also have a certain impact on the destruction of red blood cells, resulting in low hemoglobin. At this time, the patient needs to eliminate the hepatitis B virus fundamentally.

6. Drug effects: Some drugs may have side effects on red blood cells, such as chemotherapy drugs or radiotherapy.
