It’s usually a sign that the body is fighting off infection by activating theimmune system.

This article covers what lymph nodes are, why they swell, and how to treat them.

What Are Lymph Nodes?

Common causes of enlarged lymph nodes in children

Verywell / Brianna Gilmartin

Lymph fluid includeswhite blood cellsand proteins to help fight infections.

Lymphadenopathy may be localized or generalized (widespread).

Generalized lymphadenopathy may be related to a viral infection,autoimmune disorder, ordisseminated diseases.

What Causes Swelling?

Verywell / Brianna Gilmartin

Viral infections are the most common cause of lymphadenopathy in children.

Common Causes

Many young children temporarily develop swollen glands when they have an infection.

Lymphadenopathy can be especially prominent in the nodes closest to the site of infection.

Common causes of lymphadenopathy in children include:

The lymph nodes may also enlarge due to an allergic response.

This is when the body’s immune system overreacts to a harmless substance, such as pollen orpet dander.

Your child’s lymph glands may become swollen after an insect bite or a severe case of hay fever.

Lymphadenopathy might not be as noticeable as the othereffects of an allergy.

Serious Causes

Severe infections and cancer can cause fluctuating, yet persistent lymphadenopathy.

Sometimes the body is not able to effectively fight an infection, or the immune system is impaired.

Cancer cells can spread to the lymph nodes, and the immune system may be unable to destroy them.

Symptoms

Swollen lymph nodes often do not cause symptoms.

But they can be tender or painful.

Lymphadenopathy may cause symptoms due to pressure on nearby structures.

For example, it may be hard to swallow if your paratracheal lymph nodes are swollen.

What Causes Glands to Swell?

Lymph glands can swell when they produce more immune cells than usual.

This most commonly happens when your body is fighting an infection.

It can also occur due to an allergic reaction, autoimmune disease, or cancer.

The cervical, axillary, and inguinal nodes are the ones most readily felt during a physical exam.

This would be considered a red flag to healthcare providers that further investigations are needed.

For mild cases, it is best for your child to get some rest and to be comfortable.

Viral infections are generally not treated with medications and they resolve on their own.

How Can I Treat Swollen Glands in My Neck?

you might use ice and anti-inflammatory medication as directed by your healthcare provider.

Summary

Swollen lymph nodes in children indicate that your child is fighting off infection.

This happens to children often because they are frequently exposed to new infections.

Typically, a virus can cause swollen lymph nodes, but more serious conditions can also cause it.

Treatment varies depending on the cause.
