If you have mild lymphocytopenia with no underlying cause, you may not need treatment. The disorder may improve on its own.
If an underlying condition is causing your lymphocytopenia, you'll need treatment for that condition. You'll also need treatment for infections if your body is unable to fight them because of lymphocytopenia.
The main risk of lymphocytopenia is getting unusual infections, repeat infections, and/or infections that won't go away. If you have the disorder, you may get treatments to prevent infections or to treat infections you already have.
You also can take other steps to prevent infections. For example:
Know the signs of an infection, such as a fever. Call your doctor right away if you think you have an infection.
If you have a disease or condition that’s causing lymphocytopenia, you’ll need treatment for that condition.
You'll likely have regular tests to show how the treatment is working. For example, you may have blood tests to check the number of lymphocytes in your blood.
If the treatments for the underlying condition are working, the number of lymphocytes in your blood may go up.
Talk with your doctor about what types and amounts of physical activity are safe for you. You may want to avoid activities that could result in injuries or increase your risk of infections.
