Several everyday factors can cause fluid retention. Eating too much salt, remaining inactive for long periods, or spending time in extreme heat can make feet and ankles swell. Minor injuries may also trigger temporary inflammation. However, swelling that appears without an obvious reason or doesn’t improve with rest may require medical attention.
More serious causes include heart failure, kidney disease, liver problems, and circulation disorders. Warning signs include swelling in only one leg, redness, warmth, pain, or skin that remains indented after being pressed. Swelling accompanied by chest pain or shortness of breath requires immediate emergency medical care, as it may indicate a dangerous condition.
For mild swelling, elevating the legs, walking regularly, reducing excessive salt intake, and avoiding prolonged sitting may help. Compression stockings can also improve circulation when recommended by a healthcare professional. However, unexplained or persistent swelling should be evaluated by a doctor. Recognizing these warning signs early can help identify potentially serious health problems before they worsen.
