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.
Salt. One of the main causes of water retention is eating too much salty food. The main component of salt is sodium, which the body dilutes with water if too much of it is present. Salt makes you thirsty, and your body will hold on to this water.Reducing the amount of salt in your diet will help you to release a little water retention but not usually more than about 2 lbs in weight.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.
