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.
High levels of certain hormones can also make your body hold on to water. These include insulin, which is needed to process sugar; cortisone, which is produced when you are under stress; and the female hormones oestrogen (estrogen) and progesterone.ost cases of water retention are due to âidiopathic oedema (edema)â which simply means that the water retention is not being caused by a specific disease. In most cases the cause is reversible by changing what you eat and how you exercise. Read the sections below to see what kind of water retention you have.
