NHS Warning: Leg Swelling at Night Could Signal Heart Failure

The NHS has issued a warning that swelling in the legs, feet, or ankles—known as oedema—could be a sign of heart failure. The condition may be more noticeable in the morning and worsen as the day progresses, making walking uncomfortable.

Heart failure occurs when the heart becomes too weak or stiff to pump blood effectively around the body. This leads to increased pressure in blood vessels, forcing fluid into surrounding tissues and causing swelling.

The NHS describes heart failure as a long-term condition that gradually worsens over time. While it cannot usually be cured, symptoms can often be managed for many years with appropriate treatment.

Experts from Medical News Today explain that the elevated blood pressure from heart failure forces fluid out of blood vessels, resulting in oedema. Some patients may also experience depression or anxiety alongside physical symptoms.

The NHS advises seeing a GP if swelling persists or worsens. In cases of sudden or severe symptoms, patients should call 999 or visit A&E immediately.
