The lymphatic system is responsible for eliminating the excess fluid and some toxic substances from the body's tissues and organs. Consisting of a network of vessels and lymphatic capillaries, this system drains this excess liquid, in the form of lymph, into the bloodstream. Any dysfunction to the lymphatic system leads to fluid retention in the tissues which, when filling up the spaces between the cells, will cause a swelling called oedema. A physiological drainage blockage of the lymph by the lymphatic system can result from a surgical intervention, venous insufficiency, pregnancy, menstrual cycle, presence of scars, burns, obesity, among others reasons.Manual lymphatic drainage is the technique that helps the lymphatic system to eliminate the accumulated fluids and toxins. By increasing the flow and speed of lymphatic circulation, drainage decreases fluid retention, activates blood circulation, reducing symptoms and thus generating a feeling of well-being, leading to body and mental relaxation. It must be performed by qualified and experienced professionals and involves painless, smooth, and superficial movements that obey the path of the superficial lymphatic system.
