Water retention is a common problem that most people face at some point in their lives. A combination of diet, lifestyle changes, supplements, and diuretics can work together to relieve edema and stop it from returning. The biggest thing to remember is that edema is caused by a combination of too much sodium in the body and poor circulation. By reducing salt intake and encouraging the excess water to leave with diuretics, edema will quickly fade. Combining these lifestyle changes with an increased exercise regimen will also make a difference in reducing edema .
