Low Leukocytes: Causes, Symptoms, and Treatments
Leukocytes are fundamental cells of the immune system, responsible for protecting us against infections and diseases.
When the levels of leukocytes in the body decrease, we are faced with a condition known as low leukocytes or leukopenia.
Join us on this journey to understand more about this important condition and how to deal with it!
What Are Leukocytes?
Leukocytes, also known as white blood cells, are blood cells that are part of the immune system.
Their main function is to defend the body against infections and diseases, as they have the ability to recognize and destroy pathogens, such as viruses, bacteria, and other foreign organisms.
Types of Leukocytes
There are different types of leukocytes, each with specific functions in the immune response.
The main ones are: neutrophils, lymphocytes, monocytes, eosinophils and basophils.
Each type of leukocyte has unique characteristics and functions that contribute to the protection and defense of the body.
What does it mean to have low white blood cells?
When white blood cell levels in the blood are below normal, a person is considered to have low white blood cells or leukopenia.
This can be an indicator of a weakened immune system, which can increase the risk of infections and other diseases.
Definition of Leukopenia
Leukopenia is defined as a decrease in the number of leukocytes in the blood.
A person is generally considered to have leukopenia when white blood cell levels are less than 4,000 cells per microliter of blood.
Importantly, leukopenia can be a symptom of a more serious underlying condition.
Normal Leukocyte Ranges
Normal leukocyte ranges range from 4,000 to 11,000 cells per microliter of blood.
These values are usually different in children and adults.
Alert Levels
If leukocyte levels are below 3,000 cells per microliter of blood, it is considered a critical situation that requires immediate medical intervention.
Causes of Low Leukocytes
Infections
Viral and bacterial infections often cause a decrease in white blood cell levels.
These pathogens can affect the production of leukocytes in the bone marrow or cause accelerated destruction of white blood cells.
Diseases of the Immune System
Lupus and rheumatoid arthritis are autoimmune diseases that negatively affect leukocyte levels.
In these conditions, the immune system mistakenly attacks healthy cells, including leukocytes.
Nutritional deficiencies
A lack of essential vitamins and minerals, such as iron, copper, and vitamins B12 and folic, can interfere with the normal production of white blood cells in the bone marrow.
Bone Marrow Disorders
Leukemia and aplastic anemia are disorders of the bone marrow that usually cause a decrease in white blood cell levels.
Symptoms of Low Leukocytes
The symptoms of low white blood cells can vary depending on the underlying cause.
However, some of the most common include: persistent fatigue, weakness, recurrent fever, frequent infections, and difficulty fighting infections
Diagnosis of Leukopenia
Diagnosing leukopenia involves a thorough evaluation that involves blood tests, a detailed medical evaluation, a review of medical history, and a thorough physical examination.
These tests will help your doctor determine the cause of low white blood cells and establish an appropriate treatment plan.
Medical Treatments
The treatment approach for low white blood cells depends directly on the underlying cause.
In some cases, it may simply be necessary to treat the infection or illness.
In more complex situations, bone marrow-stimulating medications may be given to increase the production of white blood cells.
Additionally, your doctor may recommend dietary changes and nutritional supplements to address specific nutritional deficiencies.
