紅血球數 RBC
Red Blood Cells (RBC)
*Red blood cells (RBC) are the primary cells in blood, responsible for transporting oxygen from the lungs to tissues throughout the body and carrying carbon dioxide back to the lungs for exhalation. The quantity and functionality of RBC are crucial for maintaining normal bodily functions, and abnormalities may indicate blood or systemic health issues.
*Normal Range
Men: 4.5–6 × 10⁶/μL
Women: 4–5.5 × 10⁶/μL
RBC counts can vary based on age, gender, and physiological conditions. For example, RBC levels may decrease during pregnancy.
*Causes of Increased RBC (Polycythemia)
-Hypoxic Environments:
Living at high altitudes or suffering from chronic lung diseases (e.g., chronic obstructive pulmonary disease, COPD).
-Dehydration:
Blood concentration increases RBC levels relative to plasma volume.
-Diseases:
Polycythemia vera or certain heart conditions.
*Effects: Elevated RBC levels increase blood viscosity, heightening the risk of blood clots.
*Causes of Decreased RBC (Anemia)
-Nutritional Deficiencies:
Iron deficiency anemia, or insufficient vitamin B12 or folate.
-Blood Loss:
Acute hemorrhage or chronic bleeding (e.g., gastrointestinal ulcers).
-Bone Marrow Suppression:
Due to chemotherapy, radiation therapy, or blood disorders (e.g., aplastic anemia).
*Effects: Reduced RBC levels result in inadequate oxygen delivery to tissues, leading to fatigue, dizziness, and pale skin.
*How to Maintain Healthy RBC Levels
-Balanced Diet:
Consume iron-rich foods (e.g., red meat, leafy greens), vitamin B12 (e.g., fish, eggs, dairy), and folate (e.g., citrus fruits, legumes).
-Prevent Hypoxia:
Avoid long-term exposure to low-oxygen environments, such as smoking or excessive high-altitude activities.
-Routine Health Monitoring:
Individuals with anemia or chronic conditions should regularly check RBC counts and related metrics (e.g., hemoglobin, hematocrit).
-Moderate Exercise:
Engage in regular physical activity to support circulation and bone marrow function, but avoid excessive exertion that could lead to hypoxia.
*Conclusion
RBCs are vital for oxygen transportation and maintaining bodily functions. Abnormal RBC levels may signal anemia, hypoxia, or other health issues. A balanced diet, healthy lifestyle, and routine checkups help sustain normal RBC levels. If abnormalities are detected, consult a healthcare professional promptly to determine the underlying cause and appropriate treatment.
