血色素(血紅素) Hb
Hemoglobin (Hb)
*Hemoglobin is the primary protein in red blood cells responsible for transporting oxygen throughout the body and returning carbon dioxide to the lungs. Hemoglobin levels are a critical indicator for diagnosing anemia and assessing overall blood health, with abnormalities often reflecting systemic diseases or nutritional deficiencies.
*Normal Range
Men: 13–18 g/dL
Women: 12–16 g/dL
Note: Hemoglobin levels vary by gender, age, and physiological conditions such as pregnancy.
*Elevated Hemoglobin Levels
Causes:
-Hypoxia:
Living at high altitudes or chronic lung diseases (e.g., COPD).
-Dehydration:
Concentrated blood volume due to reduced plasma levels.
-Polycythemia Vera:
Overproduction of red blood cells by the bone marrow.
-Heart Disease:
Certain congenital heart defects.
*Effects:
Increased blood viscosity, which may raise the risk of blood clots.
*Decreased Hemoglobin Levels
Causes:
-Anemia:
Iron deficiency, vitamin B12 deficiency, or folic acid deficiency.
-Chronic Diseases:
Conditions like chronic kidney disease, cancer, or infectious diseases.
-Blood Loss:
Acute hemorrhage or chronic losses (e.g., ulcers, heavy menstruation).
-Bone Marrow Disorders:
Conditions like aplastic anemia or chemotherapy-induced bone marrow suppression.
*Effects:
Insufficient oxygen delivery to tissues, causing symptoms like fatigue, dizziness, palpitations, and pallor.
*Maintaining Healthy Hemoglobin Levels
-Balanced Diet:
Include iron-rich foods (e.g., lean meats, leafy green vegetables), vitamin B12 (e.g., eggs, dairy), and folic acid (e.g., beans, citrus fruits).
-Prevent Hypoxia:
Avoid prolonged exposure to low-oxygen environments, such as high altitudes or smoking.
-Treat Underlying Conditions:
Address chronic illnesses, blood loss, or nutritional deficiencies that may affect hemoglobin levels.
-Regular Monitoring:
Particularly important for individuals with a history of anemia or during pregnancy.
*Conclusion
Hemoglobin is vital for oxygen transport and overall health. Maintaining normal levels through a healthy diet, lifestyle, and regular checkups ensures optimal body function. If abnormalities are detected, seek medical evaluation promptly to identify and address underlying causes.
