6+ Causes of High Lymphocytes

Windowofworld.com – High lymphocytes can be known from the results of blood tests. This condition is often temporary and not dangerous. Even so in certain conditions, high lymphocytes can also be a sign of serious health problems suffered.

High lymphocyte levels are usually a sign of infection, including those caused by viruses or bacteria. But some other conditions, such as inflammation and consumption of certain drugs, can also cause lymphocyte levels to increase.

Lymphocyte Types and Functions

Lymphocytes are part of white blood cells produced by the bone marrow. Lymphocytes along with other white blood cells play a role in maintaining the body’s immune system by fighting bacteria, viruses, and toxins that enter the body so that you avoid pain.

Some lymphocytes circulate throughout the body through the bloodstream. However, there are also those who dwell in the body’s lymphatic system, such as lymph nodes, spleen, thymus gland, and tonsils.

Lymphocytes are divided into 2 types, namely B lymphocytes and T lymphocytes. B lymphocytes function to produce antibodies to attack bacteria, viruses, and poisons. While T cells work by attacking body cells that have been exposed to viruses or cancer cells.

Each lymphocyte has a different role in the immune system. There are lymphocytes that are as effector cells and some are as memory cells. Effector cells will be active if there is a cause of infection and fight the infection directly.

Meanwhile, the memory cell has a role to remember the cause of the infection that has existed before, so that if the next cause of the infection comes back, the body can respond more quickly.

Causes of High Lymphocytes

In adults, lymphocyte levels are declared high if the number is more than 4,000 per microliter. In children, normal levels vary, depending on their age. But usually, the normal limit for child lymphocytes is 9,000 per microliter and if more than this amount, lymphocyte levels can already be declared high.

As for some conditions that can affect lymphocyte levels in the body are:

  • Had had an infection some time before conducting the examination.
  • Having a heavy / stressful mind.
  • Is pregnant.
  • Just had surgery.
  • Taking certain medications, such as anticonvulsants, sulfa groups, allopurinol, or vancomycin.
  • Have undergone radiation therapy, corticosteroid therapy, or chemotherapy.

While conditions that can cause high lymphocytes include:

  • Suffer from diseases caused by viral infections, such as measles, mumps, human immunodeficiency virus (HIV), cytomegalovirus (CMV), and hepatitis.
  • Suffers from diseases caused by bacteria, such as tuberculosis and pertussis.
  • Has undergone a surgical removal of the spleen.
  • Suffers from blood cancer, such as lymphoma or leukemia.

High or low levels of lymphocytes can be determined by conducting a blood test. If you experience certain conditions that can affect the number of lymphocytes such as being pregnant or taking certain drugs, it is better to talk about this with your doctor before a blood test is done.

High lymphocytes generally do not display typical symptoms. However, some symptoms such as fever, bruising or rash on the skin, weight loss or fatigue can be a sign of high lymphocytes. So, if you experience these symptoms, consult your doctor to find out the exact cause.
