Water retention is a symptom of an imbalance in body function, causing fluid buildup in body tissues. Water retention is also called bloating or edema and can be localized or general, transient or chronic. Water retention is usually a symptom of cardiovascular disease, kidney impairment or hormone imbalance. Swollen ankles and legs after airline travel can indicate sensitivity to pressurized chambers and reduced activity on the plane. Water retention can be treated and should be checked by a medical professional to rule out an underlying condition or disease.
Water retention is the accumulation of excess fluid in body tissues or bloating. Water retention is observable in extremities, most notably in the face, ankles, legs and wrists and can cause discomfort.
Symptoms of water retention include general feelings of tenderness or tightness in the ankles, legs or feet which appear more swollen than usual (edema). When bloated areas are pressed with fingertips, temporary indentations are noticeable that don't immediately spring back.
An imbalance in hormones, excess sodium and certain medications can affect circulation and increase water retention in body tissues. Impaired kidney function can cause less fluid to be processed and excreted.
Medications, shifting hormone levels (such as around menopause or menstruation), frequent airline travel and cardiovascular disease are common causes for water retention. Changes in blood or environmental pressure can affect water retained in tissues and cleared by circulating blood.
Depending on the cause for water retention, excess fluid buildup in tissues can be treated with diuretics and reducing the amount of dietary sodium. Exercise, compression stockings and positioning to improve circulation can also alleviate water retention.
