The NHS has said that swollen legs, feet or ankles can be a warning sign of heart failure. The condition, known as oedema, may cause puffy or shiny skin, discomfort and indentations when pressure is applied. Swelling can worsen later in the day and may make walking difficult.
Other causes of oedema
Oedema can also have other causes, including sitting or standing for long periods, pregnancy, some medicines, varicose veins and kidney or liver problems.
Heart failure symptoms and advice
The NHS warns that "heart failure is a long-term condition that tends to get gradually worse over time" and that it "cannot usually be cured, but the symptoms can often be controlled for many years." Other symptoms include breathlessness, fatigue, dizziness and fainting.
The NHS advises seeing your GP if you experience persistent or worsening symptoms, and to call 999 or go to A&E for sudden or very severe symptoms.
