What should you know about causes of swollen ankles and feet in the elderly?

Gravity can cause fluid to collect around the ankles after sitting or standing for a long time. Reduced walking and weak calf-muscle pumping can add to this effect. Varicose veins may allow blood to pool in the legs, often with aching or visible twisted veins. Some medicines can cause ankle swelling. Obesity can increase pressure on the veins and make movement harder. Heart failure may cause swelling with breathlessness, reduced exercise tolerance, or a rapid change in weight. Chronic kidney disease can disturb the body’s handling of salt and fluid, sometimes causing swelling in the legs or elsewhere.

Swelling in one leg, swelling that starts suddenly, skin warmth, redness, or pain needs a different assessment from gradual swelling in both ankles. A clinician will consider the pattern, medicines, circulation, heart, kidneys, and liver.

Keep gently moving your ankles and legs, avoid sitting still for long periods, and raise your legs when resting if comfortable. Wear supportive footwear and protect stretched skin from cracks or injury. Do not reduce prescribed medicines or use compression socks without checking that they are suitable for your circulation and diagnosis. Record when swelling is worst, whether it affects one or both sides, and any breathlessness or change in urination.

Get urgent help for sudden one-sided swelling with pain, warmth, or redness; new breathlessness; chest pain; coughing blood; fainting; or rapidly worsening swelling. Arrange a medical review for persistent swelling, skin ulcers, increasing tiredness, reduced urine, or breathlessness when lying down. Older adults with new swelling should have medicines and underlying conditions reviewed even when discomfort is mild.

Ask what is causing the swelling, whether your medicines contribute, and whether blood tests, urine checks, or heart and circulation assessment are needed. Discuss safe activity, leg elevation, skin care, and whether compression is appropriate for you.
