Water retention in the legs (edema) can often be managed with lifestyle changes such as elevating your legs, staying active, wearing compression stockings, reducing salt intake, staying hydrated, and avoiding prolonged sitting or standing. However, persistent or severe swelling may indicate underlying conditions like heart, kidney, or liver problems, or blood clots, and should be evaluated by a doctor. If accompanied by red flag symptoms like pain, redness, or shortness of breath, seek immediate medical attention. Treatments may include diuretics (water tablets) or addressing the root cause.
