Exercise daily. Move the muscles and joints in the area affected by edema, especially your legs, to assist in pumping the excess fluid back towards your heart. Elevating the swollen body parts while you sleep may be helpful. Reduce salt intake. Salt can increase fluid retention and worsen edema. It is best to avoid eating raw or uncooked foods like salad and sushi; greasy or fried foods like chips, fries, and cheese; and pungent or heavily seasoned foods like kimchi, curries, and barbeque. No chocolate. No smoking, alcohol, coffee and cold beverages.
