What Causes Swollen Lymph Nodes?


If you are concerned about the size of your lymph nodes, you must see a doctor. Your doctor will ask you about your medical history and perform a physical examination to determine the cause of the swelling. Sometimes, a doctor will use high-frequency sound waves to examine your organs to determine where they are swollen.

The average size of a lymph node

There are a few different causes of swollen lymph nodes, and it is essential to find out the reason for them so that you can treat them appropriately. The most common is a viral throat infection. A viral throat infection can enlarge the lymph nodes in the neck. Usually, a lymph node is less than half an inch (12 millimetres) in size.

The size of a lymph node can help determine whether or not it is cancerous. It is considered abnormal if the node is one or more centimetres in diameter. The same is true for lymph nodes that are 1.5 centimetres in diameter. The node is considered malignant if it is more than two centimetres in diameter. However, this test is not always reliable.

Lymph nodes are small glands found throughout the body and are essential to the immune system. They function as filters and store immune cells. If they become enlarged, the lymph nodes work too hard and are overloaded. In most cases, swollen lymph nodes are a sign of an infection, but sometimes they are signs of more severe disease such as autoimmune disease.


Swollen lymph nodes can be caused by various things, including an infection or a virus. Other causes include inflammatory diseases or some cancers. A physician will examine the nodes and check for other signs of infection. They may also check for lumps or lesions elsewhere in the body.

A swollen lymph node indicates that your body is fighting an infection. They contain white blood cells, which help the immune system fight off bacteria and viruses. When these cells are swollen, the immune system works overtime to eliminate the infection. In most cases, this condition will clear up within two weeks. However, swelling is a chronic condition that can indicate cancer.

While the causes of swollen lymph nodes are varied, the common cause of swollen lymph nodes is infection. If left untreated, the infection can lead to an abscess, a localised pus collection. This pus contains white blood cells, bacteria, and dead tissue. An abscess will need antibiotic treatment and drainage.


Swollen lymph nodes are often a symptom of a more serious underlying medical condition. A doctor can diagnose the underlying cause of the swollen lymph nodes by checking for fever and examining the lymph nodes for signs of infection or lumps. They can also check for lumps in other parts of the body. Depending on the location of the lumps, a doctor may decide to recommend specific tests and perform MRI to rule out any possible diseases.

In addition to infection, swollen lymph nodes can also be caused by autoimmune disorders and specific types of cancer. Certain medications can also cause swelling of the lymph nodes. Antimalarial drugs and antiseizure drugs are common culprits. If you have swollen lymph nodes, consult your doctor right away.

Some causes of swollen lymph nodes include bacterial and viral infections. Treatment for these conditions may involve antibiotics, antivirals, or antifungals. If autoimmune diseases or cancer are suspected, treatment may include immunosuppressants or biologics. Supportive therapies may also be used to manage symptoms. Diagnosing the underlying cause is not always easy. However, proper diagnosis is critical to prevent further damage to health.


Swollen lymph nodes can be a symptom of underlying cancer or a complex infection. Your doctor may recommend a biopsy or treatment to determine the cause. Your doctor may also order blood tests to check for viral or bacterial infections. They may also perform x-rays and CT (computerized tomography) to determine the exact location of the affected lymph nodes. Your doctor may also suggest medications to help reduce the swelling.

Lymph nodes are bean-shaped structures that are an integral part of the immune system. They are located throughout the body but are more prominent in specific areas such as the neck, groin, armpits, and behind the ears. Swollen lymph nodes can be painful and require medical treatment.

Besides medications, natural treatments such as herbs and supplements can help treat swollen lymph nodes. For example, turmeric is a potent anti-inflammatory, which means it can help reduce swelling. Turmeric is also a natural analgesic, which can help relieve pain. In addition, turmeric paste can be applied to the swollen area twice daily for a week to help alleviate the swelling. Turmeric milk is also an effective herbal treatment for swollen lymph nodes.
