What are the causes of a decreased white blood cell count?

When the body is exposed to radiation or medication, or when the body is overly fatigued, it may lead to a decrease in white blood cells. In addition, after a small number of patients' bodies are infected with viruses, they will also consume white blood cells in the body, which can cause a decrease in white blood cells. After the white blood cell count drops, it may lead to a decrease in the body's immunity, and there may also be problems with severe infections or even organ disorders.

Reasons for Leukopenia

1. Radiation or Drug Effects: Long-term exposure to electronic radiation or taking drugs with mild toxicity may lead to decreased hematopoiesis in the bone marrow, which will subsequently reduce the production of white blood cells. Generally, this condition can be alleviated after staying away from the radiation area or discontinuing medication.

2. Physical Overexertion: People who are physically overworked may also experience decreased white blood cell counts. Additionally, unhealthy lifestyle habits can also lead to abnormal hematopoiesis and decreased white blood cell counts. Therefore, it is important to strike a balance between work and rest and maintain a healthy daily routine.

3. Viral Infections: Being infected with viruses can consume a large number of white blood cells in the body because white blood cells are primarily used to kill pathogens. When the pathogens are powerful, white blood cells will die in large numbers, leading to a decrease in their concentration. In such cases, antiviral drugs must be administered.

Hazards

1. Decreased Immunity: The body's immunity is primarily supported by white blood cells. When the white blood cell count decreases, the body's immunity will rapidly decline, making it vulnerable to various diseases caused by external infections.

2. Severe Infections: When a patient already has infection symptoms and their white blood cell count decreases, mild infections can easily develop into severe infections. This is because when white blood cells decrease, the body's self-healing ability is significantly weakened, and inflammation cannot be effectively controlled, leading to worsening infections.

3. Organ Disorders: Decreased white blood cell counts may lead to blood infections, which can easily cause various severe diseases in the body, such as sepsis or septicemia. These diseases may lead to organ disorders and even organ failure.
