Frequent Foot Swelling? Could Be Heart Failure, Experts Warn of Critical Symptoms

• Heart failure occurs when the heart fails to pump blood effectively, leading to sluggish blood flow and increased pressure.
• Frequent swelling in ankles or feet (medically 'edema') is a key symptom, caused by fluid leaking into surrounding tissues.
• Edema symptoms include swollen, stretched/shiny skin, and a pit forming when pressure is applied; however, not all swelling indicates heart failure.
• Other concerning heart failure symptoms: shortness of breath, constant fatigue, irregular heartbeats, persistent cough, and reduced exercise capacity.
• Risk factors include age over 65, smoking, low physical activity, high salt/fat diet, high blood pressure, coronary artery disease, and family history.
