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 infection and destroy harmful substances. When lymph nodes detect the presence of an invader, they can become swollen as they work to eliminate the threat.
In a healthy individual, lymph nodes are usually small and not easily felt. However, when they become enlarged or swollen, it can be a sign that our body is fighting an infection or reacting to an allergen or irritant.
What Causes Swollen Lymph Nodes?
Swollen lymph nodes, also known as lymphadenopathy, can occur for a variety of reasons. In most cases, swollen lymph nodes are a sign that our body is fighting an infection or reacting to an allergen or irritant. Here are some common causes of swollen lymph nodes:
Infections
Bacterial infections, such as strep throat or a skin infection, can cause swollen lymph nodes in the neck or armpits. Viral infections, like the common cold or flu, can also lead to swollen lymph nodes in the neck or groin.
Immune System Disorders
Autoimmune disorders, such as rheumatoid arthritis or lupus, can cause swollen lymph nodes as the immune system mistakenly attacks healthy tissues.
Cancer
In rare cases, swollen lymph nodes can be a sign of cancer, such as lymphoma or leukemia. This is why it’s essential to consult a healthcare professional if you experience persistent or severe swollen lymph nodes.
Allergies and Irritants
Allergies to substances like pollen, dust, or certain foods can cause swollen lymph nodes. Exposure to irritants, such as chemicals or heavy metals, can also lead to swollen lymph nodes.
If you’re experiencing swollen lymph nodes, it’s essential to consult a healthcare professional to determine the underlying cause. In the meantime, you can use online resources like Yesil Health AI to find evidence-based health answers and learn more about swollen lymph nodes. 🤕
