In blood routine tests, an increase in red blood cells (RBCs) along with a decrease in mean corpuscular volume (MCV) is generally not a normal phenomenon. This situation can be caused by physiological or pathological factors. Physiological factors, such as vigorous exercise, may lead to a temporary increase in RBCs without accompanying other discomforting symptoms. Appropriate rest usually allows for normalization. Pathological factors may include iron deficiency anemia and myeloproliferative disorders, among others.
1. Physiological Factors: After vigorous exercise, the body requires more oxygen supply, leading to accelerated blood circulation and a temporary increase in the number of RBCs. In this case, the increase in RBCs may be short-lived and generally does not cause health issues. Simply resting allows the body to adjust on its own.
2. Pathological Factors:
- Iron Deficiency Anemia: Insufficient iron in the body affects hemoglobin synthesis, resulting in smaller RBC volume. In this situation, although the number of RBCs increases, their functionality may be limited. Treatment methods include supplementing iron as prescribed, such as ferrous succinate tablets or compound ferrous sulfate and folic acid tablets.
- Myeloproliferative Disorders: These are diseases caused by abnormal proliferation of hematopoietic stem cells, which may lead to an increase in RBCs and a decrease in their volume. This condition requires professional medical intervention, which may include surgery or other treatment methods.
Apart from the aforementioned causes, other health issues such as chronic renal failure may also lead to similar blood test results. When such symptoms appear, it is recommended to seek medical attention promptly for detailed diagnosis and treatment. The situation of increased RBCs and decreased MCV should not be ignored. Early identification of potential health issues and timely adoption of appropriate measures help prevent more severe health consequences. Maintaining a healthy lifestyle and undergoing regular health checkups are important means of preserving physical health.
