brief explanation
Allergies can sometimes cause swollen lymph nodes, although this is not a common symptom of allergies. Lymph nodes swell due to an immune reaction to an allergen, such as pollen, dust mites, mold, or animal dander. Although allergies may weaken the immune system, making the body more susceptible to viruses and bacteria, secondary infections such as sinus infections or upper respiratory infections may also occur. These infections can cause swollen lymph nodes as well. If your lymph nodes are swollen, it's most likely not due to your allergies, but due to something else, like some other infection in your body.
detailed explanation
what are lymph nodes?
Lymph nodes are small, bean-shaped structures that are a part of your lymphatic system, which is part of the immune system. The lymphatic system is responsible for regulates fluid levels throughout the body and removes waste after the cells filter them from the bloodstream. It also helps protect you from disease and illness by producing and releasing certain white blood cells to attack foreign substances, such as bacteria.
why do lymph nodes swell?
Lymph nodes fill with excess lymphatic fluid and swell any time the immune system needs to remove harmful substances. The most common reason for swelling is because the body is fighting a bacterial infection or viral infection, but swelling can also occur due to immune system disorders, allergies, stress, cancers, and other conditions.
can allergies cause swollen lymph nodes?
Yes, allergies can sometimes cause swollen lymph nodes. When we encounter allergens such as pollen, pet dander or certain foods, our immune system may react by releasing histamine and other chemicals. This immune response to allergens can cause swollen lymph nodes in our body. If you have a history of particularly strong reactions to allergens, it's more likely your lymph nodes may swell. The swelling is usually temporary and should resolve once the allergen is no longer present, or the allergic reaction is under control.
how to treat swollen lymph nodes from allergies
There are several ways to treat swollen lymph nodes from allergies, including taking allergy medication, applying a warm compress, getting adequate sleep, staying hydrated, and taking an over-the-counter pain reliever. Treatment for the underlying infection or inflammation will take care of the swollen or reactive nodes.
