Leukocytosis

Leukocytosis is a condition characterized by an increase in the number of white blood cells (leukocytes) in the blood. This condition is often a response to an infection, as white blood cells play a crucial role in the body's immune response. However, leukocytosis can also be caused by a number of other factors, including certain medications, stress, and certain diseases and conditions.

Causes

Leukocytosis can be caused by a number of factors. These include:

• Infection: This is the most common cause of leukocytosis. The body produces more white blood cells to fight off the infection.
• Inflammation: This can also cause an increase in white blood cells.
• Certain medications: Some medications can cause leukocytosis as a side effect.
• Stress: Both physical and emotional stress can cause an increase in white blood cells.
• Certain diseases and conditions: These include certain types of cancer, such as leukemia, and certain immune system disorders.

Symptoms

The symptoms of leukocytosis can vary depending on the underlying cause. However, some common symptoms include:

• Fever
• Fatigue
• Bleeding or bruising easily
• Weight loss
• Night sweats
• Frequent infections

Diagnosis

Leukocytosis is typically diagnosed through a complete blood count (CBC) test. This test measures the number of white blood cells in the blood. If the number is higher than normal, it may indicate leukocytosis.

Treatment

The treatment for leukocytosis depends on the underlying cause. If the cause is an infection, treatment may involve antibiotics. If the cause is a certain medication, the medication may need to be changed. In some cases, treatment may involve addressing the underlying disease or condition causing the leukocytosis.
