What Causes Lymphoedema?
Lymphoedema develops when the amount of fluid entering the tissues exceeds the lymphatic system’s ability to drain it effectively.
There are two main types:
Primary lymphoedema is caused by an intrinsic problem with the lymphatic system. It is often, but not always, genetic and may be present from birth or develop later in life.
Secondary lymphoedema develops when a previously functioning lymphatic system becomes impaired through damage, injury or physiological overload.
Causes and contributing factors can include:
• Surgery or removal of lymph nodes
• Radiotherapy and some cancer treatments
• Injury or trauma
• Recurrent infections, including cellulitis
• Chronic venous disease
• Heart failure and other conditions that increase fluid filtration
• Obesity
• Reduced mobility
Sometimes several factors are present together, increasing the load on the lymphatic system.
Lymphoedema can affect any area of the body, not just the arms and legs.
Persistent or unexplained swelling can have a number of causes, so appropriate assessment is important.
