How to reduce leg swelling

Swelling happens when extra fluid collects in the tissues, often around the ankles and lower legs. Heat, long periods of sitting or standing, salty meals, pregnancy, some medicines, and reduced movement can contribute. Swelling may also be associated with Varicose Veins, Obesity, Heart Failure, or Chronic Kidney Disease. The pattern matters: swelling in both legs can have a different cause from swelling that appears suddenly on one side.

Notice when it began, whether it changes during the day, and whether the skin feels tight or leaves a temporary dent after gentle pressure. These details can help a clinician decide whether you need an examination, blood tests, or other checks.

When resting, support your legs on cushions so they are raised comfortably. Take short walks, flex and point your feet, and change position regularly, especially during travel or desk work. Wear comfortable footwear, keep the skin clean and moisturised, and avoid tight socks or clothing that leaves deep marks. Reducing salty processed foods may help limit fluid retention.

Do not start water tablets, compression stockings, or supplements without advice. Compression may be unsuitable when circulation to the legs is reduced, and water tablets can affect fluid balance and kidney function. A pharmacist or clinician can check what is safe with your medicines and health conditions.

Seek urgent medical help if swelling comes with shortness of breath, chest pain, faintness, coughing blood, or a fast or irregular heartbeat. Get prompt assessment for sudden swelling in one leg, especially with calf pain, warmth, redness, or tenderness. These symptoms can signal a clot or another problem needing immediate treatment.

Arrange a routine appointment if swelling persists, keeps returning, worsens, affects daily activities, or comes with reduced urine, unusual tiredness, or rapid weight change. A clinician can review medicines and check for problems affecting the heart, kidneys, veins, or circulation.

Ask: What could be causing my swelling? Should I change any medicine or activity? Are compression stockings appropriate for me? What warning signs should make me seek urgent help? Bring a list of medicines and note when the swelling appears, whether it affects one or both legs, and what makes it better or worse.
