Can abnormal blood routine lead to physical fatigue?

Abnormal blood routine may lead to physical fatigue, which is related to the type and severity of abnormal indicators.

Blood routine includes multiple indicators such as red blood cells, white blood cells, platelets, etc. When the red blood cell count or hemoglobin concentration decreases (such as anemia), the oxygen carrying capacity of the blood decreases, and the oxygen supply to the body tissues is insufficient, which can easily lead to fatigue and weakness. This fatigue is often manifested as worsening after activities, accompanied by symptoms such as pale complexion and dizziness. Mild anemia can be improved by increasing foods rich in iron and folate (such as red meat and dark green leafy vegetables), while moderate to severe anemia requires intervention after identifying the cause. Abnormal increase in white blood cells may be related to infection, and fatigue is often accompanied by fever and local inflammatory reactions; And a decrease in white blood cells may affect immunity, increase the risk of infection, and indirectly lead to fatigue. Platelet abnormalities usually do not directly cause fatigue, but when severely reduced, they may lead to a tendency to bleed, resulting in fatigue symptoms after secondary anemia. Besides blood system diseases, compensatory changes in blood routine caused by other diseases may also be related to fatigue, such as renal anemia caused by chronic kidney disease, anemia caused by tumor depletion, or white blood cell abnormalities. Partial population physical examinations have found slight fluctuations in individual indicators (such as slightly high or low platelets), which usually have no clear pathological significance. Fatigue symptoms are more likely to be related to non blood factors such as sleep deprivation and mental stress.

It is recommended that patients with persistent fatigue and abnormal blood routine seek medical attention to investigate the cause, especially focusing on special examinations such as anemia, iron metabolism, and vitamin B12. In daily life, a balanced diet can be maintained, with moderate intake of hematopoietic materials such as animal liver, lean meat, egg yolks, etc., to avoid excessive dieting. At the same time, pay attention to regulating your daily routine, ensuring 7-8 hours of sleep, moderate exercise to enhance physical fitness, but avoid aggravating hypoxia symptoms with vigorous exercise.
