What Are Lymph Nodes?
Lymph nodes are small, bean-shaped organs that play a vital role in our immune system. They are part of the lymphatic system, which helps to defend our body against infection and disease. There are hundreds of lymph nodes located throughout our body, with clusters found in the neck, armpits, groin, and behind the ears.
Lymph nodes act as filters, trapping foreign substances like bacteria, viruses, and other toxins that enter our body. They contain immune cells called lymphocytes, which help to fight off infections and diseases. When lymph nodes detect the presence of foreign substances, they can become swollen as they work to remove the infection from our body.
Functions of Lymph Nodes
Lymph nodes perform several important functions, including:
- Filtration: Lymph nodes filter the lymph fluid, removing waste products, bacteria, and other foreign substances.
- Activation of immune response: Lymph nodes activate the immune response by recognizing and responding to the presence of foreign substances.
- Production of immune cells: Lymph nodes produce immune cells called lymphocytes, which help to fight off infections and diseases.
What Causes Swollen Lymph Nodes?
Swollen lymph nodes, also known as lymphadenopathy, occur when the lymph nodes become enlarged due to an infection, inflammation, or other conditions. There are many possible causes of swollen lymph nodes, including:
Infections
Infections are the most common cause of swollen lymph nodes. These can include:
- Bacterial infections: Such as strep throat, tuberculosis, and cat-scratch disease.
- Viral infections: Such as the common cold, flu, and mononucleosis.
- Fungal infections: Such as histoplasmosis and coccidioidomycosis.
Other Causes
In addition to infections, swollen lymph nodes can be caused by:
- Cancer: Such as lymphoma, leukemia, and breast cancer.
- Autoimmune disorders: Such as rheumatoid arthritis and lupus.
- Inflammatory conditions: Such as sarcoidosis and Kawasaki disease.
- Medications: Certain medications, such as phenytoin and sulfonamides, can cause swollen lymph nodes as a side effect.
