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.
Although everyone is susceptible to edema, fluid retention does seem to be more of a problem in women. There are a couple of reasons for this tendency. For one, because of their naturally occurring, higher level of body fat, women have less water reserves, making it easier for them to become dehydrated. Additionally, some women have a problem with excess estrogen, which also causes the body to retain water.
