What causes low hemoglobin concentration?

In general, low hemoglobin concentration may be caused by factors such as blood loss, malnutrition, iron deficiency anemia, megaloblastic anemia, or aplastic anemia. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Blood Loss

Excessive blood loss due to trauma, heavy menstrual bleeding in women, or significant hemorrhage during childbirth can lead to insufficient raw materials for red blood cell regeneration, potentially resulting in low hemoglobin concentration. Maintain a balanced diet, ensure adequate nutrition, and balance work with rest.

2. Malnutrition

Long-term deficiencies in nutrients such as vitamin B12, folic acid, and iron can lead to malnutrition, impairing red blood cell production and hemoglobin synthesis, which may result in reduced hemoglobin levels. Increase intake of foods rich in high-quality protein, such as eggs, fish, and lean meat.

3. Iron Deficiency Anemia

Iron deficiency anemia occurs when the body lacks sufficient iron, directly affecting hemoglobin production and leading to decreased hemoglobin concentration. Common symptoms include pale skin, weakness, and fatigue. Follow your doctor's instructions to take medications such as compound ferrous sulfate granules, iron dextran tablets, or ferrous fumarate tablets.

4. Megaloblastic Anemia

Megaloblastic anemia is caused by impaired DNA synthesis. A deficiency in vitamin B12 or folic acid disrupts red blood cell production, leading to reduced hemoglobin concentration. Symptoms may also include mouth ulcers, poor appetite, and diarrhea. Patients may take medications such as ferrous succinate tablets, ferrous gluconate tablets, or adenosylcobalamin tablets under a doctor’s guidance.

5. Aplastic Anemia

Aplastic anemia results from reduced bone marrow hematopoietic tissue and bone marrow failure, leading to decreased blood cell production, including lower hemoglobin levels. It may also present with infections, fever, and bleeding. Under medical supervision, medications such as compound glycyrrhizin tablets, polyene phosphatidylcholine capsules, or mannanopeptide tablets may be used for treatment.

Maintaining a balanced diet, avoiding excessive blood loss, and using medications appropriately can also help prevent low hemoglobin concentration.
