Fluid Retention (Edema)
Fluid retention, medically known as edema, occurs when excess fluid builds up in the body's tissues, causing swelling and puffiness. While mild fluid retention is common and often harmless—such as swollen ankles after standing all day—it can also signal serious underlying conditions affecting the heart, kidneys, or liver. The location, severity, and accompanying symptoms provide important clues about the cause. Fluid retention can affect any part of the body but is most noticeable in the feet, ankles, legs, hands, and face. Understanding when fluid retention is a minor inconvenience versus a medical emergency helps ensure appropriate treatment and prevents complications.
