Injury or Surgery: After injury or surgery, especially those that involve lymph node removal, the lymph rushes to that area to aid healing. However, due to damage or removal of lymph nodes, fluid retention and tissue swelling in the area can occur instead. Without proper drainage, the lymph becomes toxic and harms the body. Pregnancy & Maternity: As the body retains more fluids during pregnancy, water retention arises and swelling in the ankles or arms and hands commonly occurs. These excess fluids can be expelled through lymphatic drainage massages. Unhealthy Diets: Food that is high in fat, oils and cholesterol can create congestion in blood cells. This congestion and blockages produce additional bodily waste that needs to be cleared by lymph and processed by tissues and organs. Lack of Exercise: Active and regular muscle movement keeps lymph circulating around the body and improves blood circulation. It is important to use the body’s muscles to improve lymph flow and processing.
