What can cause too many white blood cells?

When it comes to our body’s defense against illness and disease, we’ve got a whole army of soldiers fighting for us. These warriors are known as white blood cells (WBCs) and they come in a variety of shapes and sizes – each with their own unique set of skills. However, just like the rest of us, sometimes these guardians of health can get a little carried away. In this article, we’ll be exploring some potential causes behind what happens when there are too many white blood cells on patrol.

The basics

Before diving into the causes behind an overproduction or increase in WBCs (leukocytosis), let’s take a quick look at what exactly these agents do in our bodies. White blood cells are crucial components of our immune system – responsible for honing in on foreign invaders like viruses and bacteria and neutralizing them before they spread further throughout the body.

A normal range for WBC count is typically between 4,000-11,000 per microliter (/uL), although this may vary slightly depending on age group or underlying medical conditions.

When things go awry

If you find yourself with an elevated WBC count outside of that normal range, it could be indicative that something else going on within your body. Let’s explore some possible factors behind an abnormally high presence of these defenders:

Infections galore!

One common reason why someone might present with leukocytosis is due to infection; after all, if there are more bad guys floating around inside you than typical (cough COVID cough), it makes sense your immune system would respond accordingly by dispatching more troops to combat those intruders.

Some examples include:
– Pneumonia
– Urinary Tract Infections (UTIs)
– HIV/AIDS
– Malaria
– Bacterial meningitis

Inflammatory disorders

Another avenue to consider when pinpointing what causes too many white blood cells is the presence of inflammatory disorders. These types of conditions could trigger your body to need additional WBCs to fight off inflammation, resulting in increased counts.

  • Rheumatoid arthritis
  • Multiple sclerosis (MS)
  • Ulcerative colitis
  • Lupus
  • Crohn’s disease

Cancer or Leukaemia

Unfortunately, sometimes elevated WBC counts can signal something far more serious going on beneath the surface – cancer. Certain types of leukemias are characterized by an overproduction or abnormal appearance of white blood cells within the bone marrow itself.

Other considerations

In addition to these potential theories behind high WBC levels, there are several other factors that could impact general immunity and resultant production rates:

Pregnancy

During pregnancy, it’s common for women to experience an increase in their total quantity of neutrophils – a type of WBC dedicated primarily towards infection response. This doesn’t necessarily translate into full-blown leukocytosis but rather represents a natural physiological change during this period.

Allergic reactions

Our immune systems work around the clock even when they’re not fighting foreign invaders per se; certain irritants like pollen, pet dander or dust mites can activate our “defend!” mechanisms and result in heightened symtomts including too many white blood cells present.

Other miscellaneous factors include: stress/anxiety levels leading impacting hormonal balance and thyroid function negatively affecting overall immunity support/body processes

Bottom line

When considering how one might end up with too many white blood cells circulating around their bodies , there can be a variety complex elements at play ranging from simple allergies all the way up through serious illness concerns such as leukemia. While testing via samples may help diagnose root cause issues centering around high count readings periodically obtained during routine health screenings, never underestimate the significance of paying attention to your own body, particularly if you fird yourself presenting with unique or concerning symptoms.

Always consult professional healthcare providers for specific medical advice related to any diagnosis concerns/hypothesis mentioned herein.
