The presence of high erythrocytes in routine blood tests does not mean that you have a disease, because high erythrocytes are divided into the following conditions:
1. Physiological increase, mostly seen in people with slightly high erythrocyte values and normal other indicators and no other symptoms, is considered a physiological increase, such as drinking too little water, doing strenuous exercise or a lot of physical labor, too much emotion The physiological increase in erythrocytes, which is caused by too little water in the blood and the concentration of blood, can be improved by drinking more water.
2. Relative increase is caused by dehydration due to various reasons, such as diarrhea, vomiting, polyuria, burns, excessive sweating, etc. This occurs for reasons similar to the physiological increase and is caused by lack of physical water, and only requires symptomatic treatment.
3. The secondary increase is due to a disease that causes tissue hypoxia, resulting in increased erythropoiesis, such as pulmonary heart disease, emphysema, chronic carbon monoxide poisoning, etc. In addition, some tumor diseases can lead to abnormal increases in erythropoietin, such as stomach cancer, liver cancer, and nephroblastoma.
