Increase lymphocyte levels by treating the underlying cause of the disorder, says Right Diagnosis. It may be necessary to stop taking or reduce the dosage of prescription drugs responsible for the lower lymphocyte levels, and doctors may recommend agents that stimulate bone marrow may. Consuming foods high in Vitamin C, such as citrus fruits and red bell peppers, may help raise lymphocyte levels, as Vitamin C is said to increase white blood cell production, according to Healthline.
Lymphocytes are the body's main source of immune capability, according to Health Central. Having a low number of white blood cells or lymphocytes in the blood is called lymphopenia, explains Right Diagnosis. There are many illnesses that cause lymphopenia, including Graves' disease, tuberculosis, lupus erythematosus and Hodgkin lymphoma. Lymphopenia sometimes occurs after a person experiences trauma or burns, or after cortisone and acth are administered. It may also be seen in several states of congenital immunodeficiency.
Certain foods are believed to boost the body's immune system, including garlic, yogurt, almonds and green tea, notes Healthline. The high concentration of sulfur-containing compounds in garlic helps to improve immunity, while the active cultures in yogurt may stimulate the immune system. The high vitamin E content in almonds offers immunity-boosting benefits, while the amino acid L-theanine, found in green tea, may help to produce germ-fighting elements in T-cells.
