Symptom 4: Unwanted Retention – Swelling (Edema) in Legs, Ankles, and Feet
Swelling or edema, particularly in the legs, ankles, and feet, can often be an indication of systolic heart failure. This swelling is essentially fluid accumulation, a result of the heart’s inability to pump blood efficiently.
The human body is a well-balanced system, with a precise equilibrium of fluid entering and leaving the cells and tissues. In the face of systolic heart failure, this balance is disrupted. The heart’s diminished pumping capacity leads to a backflow of blood into the venous system, which increases pressure within the veins. This increased pressure forces fluid out of the blood vessels and into surrounding tissues, leading to swelling.
Individuals might first notice the swelling in their feet, ankles, or legs. The puffiness might be accompanied by a feeling of heaviness or stiffness. Moreover, the swelling can worsen throughout the day, particularly after prolonged periods of standing or sitting.
Swelling isn’t merely a physical inconvenience; it’s an indication of the body’s inability to maintain fluid balance. The presence of edema suggests that the heart is struggling with its pumping action, causing systemic implications. (4)
