According to function, lymphocytes are divided into three main categories:
1. T-lymphocytes (T cells): These cells play a central role in the adaptive part of the immune response. They help regulate the activity of other immune cells and are directly involved in the destruction of infected cells or cancer cells. T-lymphocytes are divided into several subpopulations, including helper T-lymphocytes (CD4+), cytotoxic T-lymphocytes (CD8+), and regulatory T-lymphocytes.
2. B-lymphocytes (B cells): B cells are responsible for producing antibodies. Antibodies are special protein molecules that specifically recognize foreign bodies, such as parts of viruses or bacteria, and help eliminate them from the body.
3. NK cells (natural killer cells): These cells can recognize and destroy damaged or infected cells without prior specific recognition. NK cells are an important first-line defense against some viruses and cancer cells.
Because of their important function in the immune system, the number and function of lymphocytes are often used in laboratory tests to detect certain diseases or to monitor the immune response during treatment.
An increase in lymphocytes in the blood, medically called lymphocytosis, is a phenomenon in which the number of lymphocytes in the blood exceeds normal values. It can be a temporary condition or long-term, depending on the cause. There are many different factors that can cause an increase in lymphocytes:
Regardless of the specific cause, an increase in lymphocytes indicates that the body is reacting to some kind of threat or change. Therefore, it is important to carry out detailed investigations to determine the exact cause and, if necessary, start treatment.
An increase in lymphocytes in the blood (lymphocytosis) can often be asymptomatic, i.e. occurs without any obvious symptoms. Often this phenomenon is detected by chance during routine blood tests for other reasons. However, depending on the cause of lymphocytosis, other symptoms may occur.
One of the more obvious symptoms of an increase in lymphocytes is swollen, painful or painless lymph nodes in the neck, armpits, upper thigh, or other areas of the body.
When an increase in lymphocytes is associated with an infection or blood disease, fever and night sweats may occur.
Enlarged lymph nodes in the abdominal cavity can cause abdominal pain or discomfort.
An increase in lymphocytes can cause general weakness and lack of energy as the body fights infection or disease.
Depending on the cause, symptoms of infection may occur: These may include a cough, runny nose, pain when drinking, a skin rash, or other symptoms.
In some cases, weight loss, pale skin, easy bruising or bleeding may occur.
Some patients may experience shortness of breath or difficulty breathing if the lymph nodes in the chest cavity are enlarged.
While some symptoms may be related to a temporary condition, such as a viral infection, others may indicate a more serious illness. If you experience one or more of the above symptoms, it is important to see your doctor immediately for further examinations and consultations.

Prevention of lymphocyte elevation depends on specific risk factors and potential triggers. Although it is not always possible to prevent this condition, there are some recommendations that can help reduce the risk:
While it's not always possible to completely prevent lymphocyte enlargement, these preventative measures can help reduce the risk and keep your body functioning optimally. If you think you have symptoms of an increase in lymphocytes, see your doctor as soon as possible.
Lymphocytes are an important part of the immune system responsible for protecting the body against infections and other pathogens. An increase in lymphocytes, medically known as lymphocytosis, can indicate a variety of health conditions, from simple viral infections to more serious disorders such as lymphoma or leukemia.
There are various reasons why an increase in lymphocytes can occur. It can be a reaction to an infection, blood disorders, autoimmune diseases, or other medical conditions. Typical symptoms can vary depending on the cause and may include fatigue, fever, enlarged lymph nodes, and more. It is important to determine the exact cause so that the appropriate treatment can be applied.
Taken together, an increase in lymphocytes is an important medical signal that should be taken seriously. Early diagnosis and appropriate treatment are vital to prevent more serious consequences and ensure the best health status for the patient.
