Adenitis is a medical term that refers to the inflammation of the lymph nodes, which are small bean-shaped glands that form part of the lymphatic system. The lymph nodes are responsible for filtering out harmful substances and producing immune cells to fight infection.
When the lymph nodes become swollen and tender due to inflammation, it is known as adenitis. This condition can occur in any part of the body where lymph nodes are present, such as the neck, armpits, groin, and abdomen.
Adenitis often occurs as a result of an infection, most commonly a bacterial infection, although it can also be caused by a viral or fungal infection. Common infections associated with adenitis include strep throat, tuberculosis, mononucleosis, and cat scratch disease. Other causes of adenitis can include an autoimmune disease, such as rheumatoid arthritis or lupus, and certain types of cancer.
The symptoms of adenitis can vary depending on the underlying cause but typically include swelling, tenderness, and pain in the affected area. The affected lymph nodes may also feel hard and be accompanied by redness and warmth.
Treatment for adenitis aims to address the underlying cause and relieve symptoms. This may involve the use of antibiotics for bacterial infections, antiviral medication for viral infections, or other specific treatment depending on the individual case. Over-the-counter pain relievers and warm compresses may also help alleviate the discomfort associated with adenitis.
In conclusion, adenitis is the inflammation of lymph nodes often due to infection, which results in swelling and tenderness in the affected area.
