What are lymph nodes?
lymph nodes are small bean structures found throughout the human body. They are part of the lymphatic system, which is responsible for defending the body against infections and diseases.
Lymph nodes Function
The main function of lymph nodes is to filter the lymph, a transparent liquid that circulates through the lymphatic system. The lymph contains defense cells, such as lymphocytes, which fight bacteria, viruses and other substances foreign to the body.
When an infection or inflammation occurs in a given region of the body, the lymph nodes near this region may increase in size and become sensitive to the touch. This is because they are working to combat the infection, producing more defense cells.
Location of lymph nodes
Lymph nodes are distributed throughout the body, but there are regions where they are more easily palpable, such as neck, armpits and groin. In addition, there are internal lymph nodes, which are not palpable, but perform the same function of filtering the lymph.
How to examine lymph nodes?
To examine lymph nodes, careful inspection and palpation of the regions where they are located. It is important to observe the size, consistency and sensitivity of lymph nodes, as changes in these characteristics may indicate some health problem.
- Begin the examination through the neck region, pressing gently with your fingers looking for increased or painful lymph nodes.
- Then examine the armpits, raising your arm and pressing the region with your fingers.
- Finally, check the groin region, pressing gently with your fingers.
If any altered lymph node is identified, it is important to seek medical attention for a more detailed assessment and investigation of the cause.
When to look for a doctor?
It is recommended to see a doctor if any altered lymph node is identified, especially if it is increased in size, painful or fixed on site. These can be signs of infection, inflammation or even more serious diseases such as cancer.
In addition, if lymph nodes are accompanied by other symptoms, such as fever, inexplicated weight loss, night sweats or intense fatigue, it is also important to seek medical attention.
In case of doubts or concerns, it is always recommended to consult a health professional for proper assessment.
Conclusion
lymph nodes play a key role in defending the body against infections and disease. They are present all over the body and can be palpable in some regions. It is important to be aware of changes in the lymph nodes and seek a doctor in case of doubts or worrying symptoms.
