Red Light Therapy for Lymphedema

Lymphedema is a condition characterized by chronic swelling in one or both arms or legs. It occurs due to a blockage in the lymphatic system, which is a crucial part of the immune system. When lymph nodes are unable to drain properly, fluid accumulates in tissues, resulting in uncomfortable and painful swelling, along with other complications.

There are two main types of lymphedema: primary and secondary. Primary lymphedema is an extremely rare inherited condition. On the other hand, secondary lymphedema, which is far more common, is caused by another underlying disease or condition, such as injury to lymph nodes, removal of lymph nodes during cancer surgery, radiation treatment for cancer, or cancer itself.


Lymphedema swelling can vary from barely noticeable to extremely severe. Severe swelling can limit the range of motion, cause recurring infections, and even harden or thicken the skin.


Lymphedema is a condition that can debilitate both physically and psychologically and currently has no known cure. The standard treatment for lymphedema is complete decongestive therapy (CDT), which incorporates techniques such as manual lymphatic drainage, multilayer bandaging, compression bandages, limb elevation, and physical therapy. It may also include oral medications and massage. Healthcare practitioners usually recommend incorporating regular exercise into the treatment plan to help bodily fluids move naturally.


Although there are methods that can effectively manage lymphedema symptoms, they do not deal with the root cause of the problem or restore normal lymphatic flow. As a result, the condition may persist for years or even a lifetime, requiring continuous treatment.


Red light therapy, also known as low-level light therapy (LLLT) or photobiomodulation, can help the body's natural mechanisms combat the underlying causes of lymphedema. It is a safe, gentle, and non-invasive therapy that stimulates the natural functioning of lymph nodes, including proper drainage and reduces swelling. By using red light therapy, one can promote the body's natural healing process.


Low-Level Laser Therapy (LLLT) that uses red and/or near-infrared (NIR) waves can help reduce swelling by promoting cellular activity and restoring normal lymphatic function. LLLT can be used for both primary and secondary lymphedema. However, secondary lymphedema can be more challenging to treat because it may not become noticeable until months or even years after cancer treatment or injury.


Red light therapy is known to stimulate energy production in cells, which can lead to increased functionality of the cells. Similar to how you feel when you are full of energy, energized cells can use their resources for their functions, resulting in better performance in their jobs, self-repair, and successful replication. This, in turn, enables the body to work towards repairing and rebuilding larger systems such as the lymphatic system.


Low-level laser therapy (LLLT) is believed to have several benefits, including stimulating lymph fluid movement, lymphangiogenesis, and macrophage activity. It can also help soften fibrotic tissues and improve tissue contractility, which in turn helps with lymph transport through the lymphatic vessels. These mechanisms work together to increase the movement of fluid from extracellular spaces into the lymphatic system for transportation.


By increasing lymph flow, LLLT can prevent the buildup of lymph in the body's tissues. It reduces inflammation, improves circulation, and assists the body in flushing out excess fluid, resulting in a reduction in the volume and circumference of the affected limb(s). This reduction in swelling helps relieve pressure, and as the skin softens, it can help reduce pain and increase the range of motion. To achieve better and faster results, using LLLT as a complementary therapy with CDT can provide immediate relief from edema and promote normal lymph vessel functioning.



For long-term maintenance, a combination of regular exercise and LLLT can help keep your lymphatic system functioning normally.
