What Is Lymphedema in Lower Extremities?
The lymphatic system is a vital part of the body’s waste removal process. It collects excess fluid and proteins, handling up to 8 liters daily. This network of vessels and nodes ensures proper fluid balance, preventing buildup in tissues.
Understanding the Lymphatic System
The lymphatic system acts as the body’s drainage network. It transports protein-rich fluid through superficial and deep vessels. When functioning correctly, it maintains health by removing waste and supporting the immune system.
Damage to this system, often from surgery or trauma, can disrupt its function. This leads to fluid accumulation, increasing the risk of infections by 70%. Understanding how the lymphatic system works is crucial for preventing complications.
How Lymphedema Develops
Secondary cases of this condition are often linked to cancer treatments or surgical interventions. In fact, 90% of secondary cases result from such damage. Fluid buildup creates an ideal environment for bacterial growth, making infection prevention essential.
| Lymphatic System Function | Risk of Damage |
|---|---|
| Collects excess fluid and proteins | Surgery or trauma disrupts flow |
| Maintains fluid balance in the body | Cancer treatments often damage nodes |
| Supports immune system function | Fluid buildup increases infection risk |
Common Symptoms of Lymphedema in the Legs
Swelling in the legs often starts subtly but can progress without proper care. Recognizing the early signs is crucial for timely intervention. This section explores the symptoms and complications associated with this condition.
