'''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.

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[edit]

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[edit]

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

Diagnosis[edit]

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[edit]

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.
