Foot and ankle swelling isn’t just “a bit of puffiness” — it’s your body holding onto fluid. This quick-read guide answers the most common questions about oedema — short, sharp, and helpful.
Common Questions About Oedema in the Feet
Q: What is oedema?
A: Oedema is swelling caused by excess fluid building up in the tissues under your skin.
Q: What causes oedema in the feet and ankles?
A: Standing or sitting too long, heat, pregnancy, injury, certain medications, or medical issues like heart, kidney, or liver problems.
Q: Is oedema the same as water retention?
A: Yes — it’s the visible swelling that happens when your body retains too much fluid in one area.
Q: What are the symptoms of oedema?
A: Swelling, puffiness, shiny or tight skin, heaviness, and sometimes a dent (“pitting”) when you press the skin.
Q: What is pitting oedema?
A: Pressing on the swollen area leaves a dent that takes time to disappear — often linked to circulation or organ issues.
Q: Can oedema be harmless?
A: Yes — mild swelling from heat, long flights, or standing is usually temporary and not dangerous.
Q: When is oedema a sign of something serious?
A: Sudden, severe, or painful swelling, or swelling with shortness of breath, chest pain, or skin colour changes needs urgent medical help.
Q: Can injury cause oedema?
A: Yes — sprains, fractures, and minor knocks can cause local swelling as part of healing.
Q: Which medical conditions cause chronic oedema?
A: Heart failure, kidney disease, liver disease, chronic venous insufficiency, and lymphatic disorders.
Q: Can medications cause oedema?
A: Yes — some blood pressure tablets, steroids, hormones, and anti‑inflammatories can cause fluid retention.
Q: How is oedema diagnosed?
A: Physical exam and history, with tests (blood, urine, ultrasound, ECG/echo) to assess heart, liver, kidneys, and veins.
Q: How is oedema treated?
A: Treat the cause + lifestyle steps: elevate legs, wear compression socks, move regularly, reduce salt, and manage weight.
Q: Do compression socks help oedema?
A: Yes — they reduce pooling by improving venous return in the lower legs and feet.
Q: Can exercise help reduce oedema?
A: Definitely — gentle walking, ankle pumps, and calf raises boost circulation and lymph flow.
Q: Does diet affect oedema?
A: Yes — high salt worsens fluid retention; a balanced diet with adequate protein and potassium‑rich foods can help.
Q: Can dehydration cause oedema?
A: Paradoxically, yes — dehydration can prompt the body to hold onto water, causing swelling.
Q: Is oedema common in pregnancy?
A: Yes — hormonal changes, more blood volume, and pressure on pelvic veins often cause third‑trimester swelling (seek help for sudden severe swelling).
Q: Can shoes make oedema worse?
A: Yes — tight shoes or socks restrict circulation and aggravate swelling. Choose soft, wide, adjustable styles.
Q: How long does oedema last?
A: Temporary oedema can resolve in hours or days; chronic oedema persists until the underlying cause is treated.
Q: Can untreated oedema cause complications?
A: Yes — long‑term swelling can lead to skin changes, ulcers, infection (cellulitis), or reduced mobility.
