What Do Lymph Nodes Do?
Reviewed: Dr. Gromatzky
8. Lymphadenopathy and Disease
Lymphadenopathy is actually a relatively common condition and is usually caused by disease. Quite simply, when there are viruses or bacteria in the body, the lymph nodes have a lot of work to do to deal with the problem. With more work to be done, more lymphocytes are needed, and the glands swell as a result.
Lymphadenopathy can occur even in relatively benign conditions like the common cold, while the flu is also a potential cause. If there are a lot of bacteria present because of something like an ear infection, this can also cause the glands to become swollen.
