Water and Fluid retention in legs, also known as edema, is a medical condition caused by abnormal accumulation of water or fluids in the bodyâs tissues. Though excess water can be accumulated anywhere in the body, the most common areas are the ankles and legs.
When sitting or standing in one position for a long time, stretch your legs and move around every couple of hours. Support hose, which you can buy at drugstores, also promote good circulation. And consider cutting your salt intake to a teaspoon or less daily, which helps reduce water retention. If none of these remedies seems to help, a medical issue such as heart failure, kidney failure, or side effects of prescription medications may be to blame. Work with your doctor to rule out these more serious causes.
