What’s causing my swollen lymph nodes?
In general, there are several reasons why someone might have swollen lymph nodes. One reason could be due to a viral infection such as Epstein Barr Virus (EBV). Another possible reason could be due to other types of infections such as HPV or HIV. A third possibility is due to certain medications taken by patients for medical purposes. Finally, some people may develop enlarged lymph nodes because they have a genetic predisposition to having them.
A person’s immune system can become overactive when it detects something foreign in the body. When this happens, the immune system attacks healthy cells and tissues. These abnormal cell changes can lead to swelling of lymph glands which then results in symptoms such as fatigue, weight gain, feverishness and chills. Other symptoms include pain behind your eyes or in your back or legs.
The first step in treating swollen lymph nodes is to identify what is causing them. There are many causes for swollen lymph nodes, but the most common ones include:
Viral Infections – EBV (Epstein Barr Virus) and Human Papillomavirus (HPV) are two viruses that can cause these kinds of symptoms. Both viruses can affect different parts of the body, but they tend to attack the immune system.
Infections – Bacterial and fungal infections can also cause swollen or tender lymph nodes. These types of infections are more serious and can spread if not treated right away.
Diseases – Diseases that can cause swollen lymph nodes include HIV, Lyme disease and mononucleosis.
Cancer – Certain types of cancers, like Hodgkin’s disease and non-Hodgkin’s lymphoma can cause swollen lymph nodes due to abnormal cell growth in the body.
Medical Treatments – Anytime you have some type of medical procedure or undergo chemotherapy, the treatment can cause swollen lymph nodes.
Most of the time swollen lymph nodes are not a serious medical condition. If you do not have any other symptoms besides swollen lymph nodes, then rest, increase your fluid intake and eat nutritious foods until the fluid reduces naturally. Lymph nodes can become enlarged due to stress, so if this is the case for you, try some stress management techniques to see if this helps reduce the size of the swollen lymph nodes.
If your swollen lymph nodes are accompanied by other symptoms such as a fever, night sweats, or weight loss, see your doctor immediately. These are possible signs of an infection and you should get checked out right away. Most of the time swollen lymph nodes are harmless and can be treated at home, but it is best to see your doctor before starting any type of treatment on your own.
