What should you know about both feet and ankles swollen?

This type of swelling is called oedema. It may be more noticeable after standing or sitting for a long time and may leave a temporary indentation when pressed. The pattern, speed of onset, and other symptoms help a clinician work out the cause.

When both sides are affected, contributors can include prolonged inactivity, pregnancy, excess body weight, vein problems, and some medicines. Heart failure can present with swelling in both feet and ankles, sometimes alongside breathlessness, tiredness, or a need to sleep more upright. Chronic kidney disease can present with swelling when the kidneys do not regulate salt and fluid normally. Varicose veins can present with ankle swelling that is worse later in the day, especially with aching or heavy legs.

Swelling alone does not identify its cause. A clinician may ask when it began, whether it changes overnight, what medicines you take, and whether you have breathlessness, chest discomfort, reduced urine, or rapid change in weight. An examination and, when appropriate, blood or urine tests can help guide the next step.

If the swelling is mild and you otherwise feel well, avoid sitting or standing in one position for long periods. Take gentle walks, move your ankles regularly, and raise your legs when resting. Wear comfortable footwear and avoid tight socks around the ankles. Keep a simple record of when the swelling appears and whether it improves after sleep.

Do not stop prescribed medicines or start water tablets without medical advice. Arrange a routine appointment if the swelling persists, returns, or is gradually increasing. Bring a list of medicines and any home readings you already monitor, such as blood pressure.

Seek urgent medical help if swelling comes with severe or new breathlessness, chest pain, fainting, confusion, or coughing blood. Get prompt assessment for rapidly worsening swelling, a very painful or hot area, fever, or swelling that is markedly greater on one side. Reduced urine or feeling suddenly very unwell also needs prompt attention.

If you are pregnant and develop sudden swelling with a severe headache, vision changes, pain beneath the ribs, or feeling unwell, contact urgent maternity care. These warning signs need assessment even when the swelling itself seems mild.

Ask what causes are most relevant given the timing and whether your medicines could contribute. You can also ask whether you need tests for heart, kidney, or vein problems, which symptoms should prompt urgent review, and whether compression garments or changes to activity are suitable for you.
