As a result, if you have a low lymphocyte count of any type, you may be more vulnerable and susceptible to disease and infection. You should go for a test to see if you have HIV/AIDS, as a low lymphocyte count can be indicative of these things, especially if you have been feeling very low and run-down recently, or have been prone to things like colds or minor infections.
If your tests for HIV/AIDS come back as negative, you should still persevere to find out the cause of your low lymphocyte count. A low number of lymphocytes can be caused by very serious conditions, such as the failure of the right ventricle of the heart, leukemia, Hodgkin's disease, lymphatic cancer, malnutrition, stress and trauma. However, low lymphocyte counts can also be caused by some prescription medicines. For your own health and safety, please consult your doctor before deciding to stop taking any prescription medication.
Treatment of lymphocyte deficiencies will involve you working with a doctor or a team of doctors in order to identify the exact cause of your lymphocyte deficiency - only when the root is identified can the problem be treated. If your low lymphocyte count is due to medication, it should return to normal within a few days of your intake of the drug ceasing. However, if the cause for your low lymphocyte count is due to something else, treatment can take years.
