Swollen lymph nodes are often a sign that your immune system is actively working. In the event of an infection, they swell up to fight pathogens. They can usually be felt as bumps around 1 cm in size, especially in the armpits, neck, groin and back of the knees. There is no set standard value for the size of lymph nodes, but if the diameter is more than 1.5 cm, you should pay attention. Causes of swollen lymph nodes Lymph nodes swell for various reasons, one of the most common causes is infections. The lymph nodes filter and fight pathogens and other harmful substances from the lymph fluid. When they encounter dangerous pathogens, defense cells multiply in the lymph nodes, causing them to grow larger. A typical viral infection that can lead to swollen lymph nodes is glandular fever, also known as the "kissing disease". In addition to viral infections such as measles and rubella, bacterial infections, autoimmune diseases such as lupus or rheumatoid arthritis, and cancer can also lead to swollen lymph nodes. Malignant or harmless - when do I need to see a doctor? The most important question with swollen lymph nodes is: when should I see a doctor? If the lymph nodes have been swollen for more than three weeks without any noticeable infection, you should definitely consult a doctor. This is especially true if the swelling is painless, the lymph nodes cannot be moved, or are firmly attached to the surrounding tissue. The size is also crucial: a diameter of more than 2 cm is a warning sign. Additional symptoms such as night sweats, fever, and unintentional weight loss could indicate a serious illness. Diagnosis and treatment options To make a diagnosis, the doctor will perform a thorough medical history and physical examination. Depending on the findings, a full blood count or biopsy may be necessary to rule out serious illnesses. For bacterial infections, an antibiotic may be prescribed. It is important to take antibiotics as prescribed to avoid the development of resistance. ▬ About this channel ▬▬▬▬▬▬▬▬▬▬▬▬▬ With “Video Visit Dr. Weigl” you have found the current and medical-scientific channel that describes topics related to pain, #medicine and #health in an understandable way but based on facts, guidelines and studies. ▬ Even more videos ▬▬▬▬▬▬▬▬▬▬▬▬▬ Lymphedema: https://bit.ly/Lymphoedem_Video Our liver - structure, function and important diseases: https://bit.ly/Leber_Video Our kidneys - tasks & functions: https://bit.ly/Nieren_Video Stroke: First aid & saving lives in the event of a stroke: http://bit.ly/Schlaganfall_Video Our heart & blood circulation explained simply: https://bit.ly/Herz_Video ▬ Social Media ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ►Facebook: https://bit.ly/facebook_DrWeigl ►Website: https://doktorweigl.de ►TikTok: / doktorweigl ►Instagram: / doktorweigl ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Legal notice / disclaimer: The videos are for your information only and never replace personal advice, examination or diagnosis by a licensed, qualified specialist.
