Lymphedema: Factors contributing to its occurrence, causes identified, and demographics involved
Secondary lymphedema, a condition characterised by the swelling of certain body parts due to damaged lymphatic vessels, can affect individuals who have undergone certain medical procedures or have certain health conditions. Here's a closer look at the risk factors and treatment options for secondary lymphedema.
Risk Factors
Secondary lymphedema can be triggered by a variety of factors. One of the most common risk factors is lymph node damage from surgery or radiation therapy, particularly after cancer treatments such as breast cancer surgery. The risk increases with the extent of lymph node removal, with sentinel lymph node biopsy having a 5-17% risk, and axillary lymph node dissection a 20-53% risk.
Other risk factors include infections like cellulitis or parasitic infections (e.g., filariasis in tropical regions), obesity or being overweight, older age, chronic inflammatory conditions, multiple surgeries or trauma, and prolonged standing.
Treatment
Treatment for secondary lymphedema involves a combination of approaches aimed at reducing swelling and preventing complications. Limb elevation and exercises to promote lymph fluid drainage are essential, as is keeping the affected limb clean and dry to avoid infections.
Compression therapy, including special elastic stockings or pneumatic compression devices, is also commonly used. Manual lymph drainage massage, a specialized therapy to stimulate lymph flow, may also be recommended, although it is not advised if cancer is present in the limb.
Surgical options, such as lymph node transplantation, lymphovenous bypass, and liposuction, may be considered in some cases. Antibiotics are often used to treat or prevent infections, which people with lymphedema are more prone to.
Additional lifestyle advice includes avoiding tight clothing that can restrict lymph flow, minimizing prolonged standing, and maintaining a low-salt diet. People with mobility impairments may benefit from speaking with occupational therapists or physical therapists who specialize in lymphedema.
It's important to note that there is no cure for lymphedema, but with early diagnosis and treatment, doctors can manage the condition and reduce its physical and emotional impact. Exercise, medications, and skin care are all important components of effective lymphedema management.
