Water retention, also known as edema is an abnormal buildup of fluid in body tissues. Feet, hands, and ankles are most commonly affected, but swelling can occur throughout the body. Causes of water retention include too much salt in the diet, poor nutrition, pregnancy, premenstrual syndrome, the use of hormonal birth control, arthritis, circulatory problems, burns, certain medications, and liver, kidney, heart, and lung diseases. Treatment options may include a low salt diet, diuretics, medication changes, support stockings, dietary adjustments, or hormone replacements.
