Low lymphocytes can be treated with exercise, diet to boost the body’s immune system, or with medication. You should seek medical advice and treatment under the guidance of your doctor. If low lymphocytes are caused by a decline in autoimmunity you can try to increase the number of lymphocytes by exercising every day, eating a balanced diet of fresh vegetables and fruits, and eating more nutrient-rich foods to improve your immunity. If low lymphocytes are considered to be due to a viral infection, the lymphocyte count can be increased by using antiviral medications such as ribavirin and entecavir. For immunodeficiency diseases, etc. can be treated by direct transfusion of component blood, etc. If you have low lymphocytes, you should consult a doctor for a clear diagnosis and follow the doctor’s instructions. The use of drugs must follow the doctor’s instructions, not blindly use their own drugs, so as not to cause adverse consequences.
