Leg Swelling Can Signal Heart Failure, Making Medical Checks Important

Changes in the legs, particularly persistent swelling, can be a warning sign of heart failure and should prompt medical assessment. The condition occurs when the heart cannot pump blood effectively enough to meet the body’s needs.

Heart failure may develop suddenly after a heart attack or an infection that affects the heart. It can also emerge gradually as ongoing strain weakens the heart or reduces its ability to fill and pump properly.

When the heart struggles to circulate blood, fluid can build up in the tissues, causing swelling in the feet, ankles and legs. However, swelling alone does not confirm heart failure, as it can have several other causes.

New, persistent or worsening swelling should be checked by a healthcare professional, especially when accompanied by breathlessness or unusual fatigue. Severe breathlessness or chest pain requires urgent medical attention.
