What effects could removal of lymph nodes have on the body?

Removal of lymph nodes can lead to lymphedema, which is a condition characterized by the accumulation of lymphatic fluid in the tissues, commonly occurring in the extremities. Lymph nodes play a critical role in the lymphatic system, which is essential for draining excess fluid from tissues, maintaining fluid balance, and facilitating immune responses. When lymph nodes are removed, this drainage system can become impaired, resulting in swelling due to the inability to properly transport lymph fluid away from the area. This can lead to complications like discomfort and skin changes.

In contrast, while the immune system's effectiveness may be reduced due to fewer lymph nodes available for filtering antigens and producing immune responses, lymphedema is a more immediate and noticeable consequence of their removal. Additionally, although there is an increased risk of infections due to disrupted lymphatic drainage, lymphedema is a more specific and direct effect resulting from this surgical procedure. Dehydration is not a direct consequence linked to the removal of lymph nodes. Overall, the presence of lymphedema highlights the crucial function that lymph nodes serve in maintaining fluid homeostasis and managing the body’s immune functions.
