What Cause White Blood Count To Be Low – Dear MAYO CLINIC: My 16-year-old grandson was recently diagnosed with a low white blood cell count after two trips to the ER with migraine headaches, vomiting, and temporary vision loss. What could cause a low white blood cell count at his age? I’m worried it’s something serious and I’m wondering what other tests should be done.
Answer: Many diseases and conditions can cause a low white blood cell count. It’s hard to say what the specific cause might be in your grandson’s situation without more information. It is unlikely that the low count is related to her migraines and other symptoms. It would be wise to have another blood test to see if the problem persists. His doctor can then decide if he needs further evaluation.

What Cause White Blood Count To Be Low
Blood has several components. In addition to white blood cells that fight infection, red blood cells carry oxygen and platelets help blood clot. Bone marrow, the spongy tissue inside bones, makes blood cells.

There are several types of white blood cells. Neutrophils fight fungal and bacterial infections. Lymphocytes protect the body from viral infections. Monocytes help remove dead or damaged tissue and regulate the body’s immune response. Eosinophils are white blood cells that fight disease. Basophils play a role in wound healing, infection, and allergic reactions.
One of the most common causes of low white blood cell counts is a viral infection. These infections can sometimes temporarily stop the production of blood cells in the bone marrow, so the number of blood cells decreases. The stones usually return when the body recovers from the infection. For most people, this temporary drop in blood cells has no long-term effects.
Some medications can also cause low white blood cell counts because they can destroy white blood cells or damage the bone marrow. For example, taking antibiotics can sometimes cause an abnormal drop in neutrophils, a condition known as neutropenia. With this in mind, it may be helpful for your grandson’s doctor to review any medications he is taking to see if they may be causing changes in his blood cell count.
Many other conditions and disorders can also cause neutropenia. For an overview of this condition and more details on how it is diagnosed and treated, watch this video from the Mayo Clinic.
What Is Neutropenia?
The list of other possible causes of a low white blood cell count in a person is long. Autoimmune disorders, congenital disorders that affect bone marrow function, diseases of the spleen, some infectious diseases, cancer, and parasitic diseases, among others, can cause low white blood cell counts.
A good next step for your grandchild would be to have a complete blood count. This test measures components in the blood. The specific type of white blood cells that this test shows is low in your grandchild, as well as the results of measurements of other blood components, can help determine what may be causing the decrease.
The other symptoms you mention—headaches, vision loss, and vomiting—should also be addressed with a physical exam, a review of your grandson’s family and medical history, and any additional tests the doctor recommends. Even if these symptoms are not related to his low white blood cell count, it is important to investigate and identify the cause. – Carola Arndt, M.D., Pediatric Hematology/Oncology, Mayo Clinic, Rochester, Minn.

According to the American Academy of Pediatrics (AAP), the average American toddler spends two hours a day in front of a screen. low. White blood cells (also called leukocytes) are part of the immune system and are the cells that protect your body against infections by bacteria, viruses, fungi, and parasites. A low white blood cell count is also known as leukopenia.
White blood cells are very important for health. It is impossible to live without them. Microorganisms that cause disease are literally everywhere, but most people don’t get sick because they have a large number of white blood cells that provide protection. A low white blood cell count often means there is a problem in the body, so it is not considered normal.
There are several types of white blood cells. Each has its own specialized purposes and different lifespans. There are monocytes (morph into other white blood cells), lymphocytes (release antibodies, regulate immunity, and kill infected human cells), basophils (initiate inflammatory reactions), eosinophils (kill parasites and cause allergic reactions), and neutrophils (master killers). bacteria and fungi).
Rbc Blood Test: Normal Ranges And Diagnostic Uses
Our bodies continuously produce millions of different white blood cells to replace worn out or dead cells. Therefore, their number mostly remains relatively stable. The immune system skillfully regulates the amount of white blood cell activity, increasing or decreasing the number of a particular type as needed in the situation. Even at times when we put ourselves at risk, such as eating dirty or spoiled food, inhaling germ-laden dust, being in crowded places, or places like airplanes, gyms, or hospitals, we often don’t get sick because we have a good supply of white blood cells. which kills pathogens before they cause infection.
If we get sick, the immune system will initiate a series of actions to stop the growth of or kill invading pathogens, as well as destroy infected or dying cells in the body. Infection often causes a sharp increase in the number of white blood cells. Doctors can easily tell if you have an infection if they see that your white blood cell count is higher than normal. Increased white blood cells give the body a better chance of stopping infection.
Of course, there are cases when the number of leukocytes falls. In most cases, it requires a thorough examination, as it is often associated with health problems, some of which are serious. A low white blood cell count is not a diagnosis or a medical condition. This is only a conclusion after a routine blood test.
The correct term for a blood test or examination is a complete blood count or CBC. Doctors often order a CBC because it analyzes the number of cell components, including white blood cells. The normal threshold for the number of white blood cells can vary. The Mayo Clinic says the normal range is 3.5 billion to 10.5 billion cells per liter of blood. Meanwhile, MEDLINE Plus states that 4,500 to 11,000 white blood cells per microliter (μl) is normal.
Tuesday Q And A: Numerous Conditions Can Lead To Low White Blood Cell Count
A CBC is the only way to determine the number of white blood cells in the body. Your doctor may order several CBC tests to monitor your blood cell count.
The main purpose of white blood cells is to protect the body from infection by microorganisms. If their numbers are too low, you may become vulnerable to infections. Most people actually do not experience any symptoms if their white blood cell count is very low.
If you have a low white blood cell count for a period of time, you may have an increased frequency of illness or infections than usual.

All microorganisms, except HIV, cannot attack white blood cells. Meanwhile, killing microorganisms is the main purpose of white blood cells. The body also naturally produces more white blood cells in case of infection or inflammation. This explains why infections cause an increase in the white blood cell count.
As mentioned earlier, our body is constantly producing white blood cells. White blood cells are produced in the bone marrow, as are other blood components. A low blood cell count means that something is wrong with the production of white blood cells.
In most cases, a low white blood cell count is the result of disease. Some treatments can cause it as a side effect. Malnutrition and lack of nutrients can also cause a decrease in the number of white blood cells.
A low white blood cell count is often associated with disease. Among the most common causes is a serious infection that may use up white blood cells faster than they can be produced. A severe infection can develop if the disease is not treated or does not respond to treatment. It often occurs in infants, very young children, or the elderly.
Best Remedies To Increase White Blood Cell Count At Home
A low white blood cell count is often a symptom of immunodeficiency or a weakened immune system. As you learned in school, white blood cells are the powerhouse of the immune system. A low white blood cell count in a CBC can often reveal the cause of an immunodeficiency. Some of the most common conditions that cause immunodeficiency include systemic lupus erythematosus
