What is a High White Blood Cell Count (Leukocytosis)?

A high white blood cell count, also known as leukocytosis, signifies an increase in the number of white blood cells in your blood. White blood cells are crucial components of your immune system, fighting off infections and foreign invaders. During pregnancy, a slightly elevated white blood cell count is fairly common due to the body's natural physiological changes. However, a significantly high count may indicate an underlying health issue requiring medical attention. Understanding the difference is key to ensuring both your health and the health of your baby.

Common Causes of Elevated White Blood Cell Count During Pregnancy

Several factors can contribute to a high white blood cell count during pregnancy. These range from normal physiological changes to more serious infections.

1. Normal Pregnancy Changes:

Physiological Leukocytosis: Pregnancy itself often leads to a moderate increase in white blood cells. Your body is working harder, and this is a natural response to support the growing fetus and protect against potential infections. This is usually not cause for concern.

2. Infections:

Viral Infections: Common viral illnesses like the flu, colds, or even a urinary tract infection (UTI) can significantly raise your white blood cell count.
Bacterial Infections: Bacterial infections, such as pneumonia, strep throat, or other severe bacterial infections, also trigger a substantial increase in WBCs.
Other Infections: Less common infections like toxoplasmosis, cytomegalovirus (CMV), or listeriosis can also cause an elevated white blood cell count. These infections can pose significant risks to the developing fetus.

3. Other Potential Causes:

Stress: High levels of stress can impact your immune system, potentially leading to an elevated white blood cell count.
Dehydration: Severe dehydration can affect blood cell counts.
Certain Medications: Some medications can influence white blood cell production.
Underlying Medical Conditions: In rare cases, an elevated white blood cell count may indicate an underlying medical condition like leukemia, although this is less common during pregnancy.

How is a High White Blood Cell Count Diagnosed During Pregnancy?

A high white blood cell count is typically detected through a routine complete blood count (CBC) test. This is a standard blood test performed during prenatal care. Your doctor might order additional tests if the results are significantly abnormal or if they suspect a specific underlying infection or condition. These may include blood cultures to identify the type of infection, urine tests to check for UTIs, or imaging studies such as X-rays or ultrasounds.

What are the Treatment Options for a High White Blood Cell Count During Pregnancy?

Treatment for a high white blood cell count during pregnancy depends entirely on the underlying cause. If the elevation is due to normal physiological changes, no treatment is usually necessary. If an infection is the culprit, your healthcare provider will prescribe appropriate antibiotics or antiviral medications. The choice of medication will take into account the safety of both mother and baby. In rarer cases, where underlying conditions are involved, treatment will be tailored to the specific diagnosis.

When Should I Seek Medical Attention?

While a mildly elevated white blood cell count during pregnancy is often normal, you should contact your doctor or midwife immediately if you experience any of the following symptoms alongside a high WBC count:

Fever
Chills
Severe fatigue
Persistent cough or shortness of breath
Pain or burning during urination
Vaginal discharge or bleeding
Swollen lymph nodes

Always consult your doctor or healthcare provider for any concerns about your health during pregnancy. They can provide accurate diagnosis and personalized treatment plans. Prompt medical attention is crucial to address any potential health complications promptly and effectively.
