What is a common symptom of congestive heart failure?

A common symptom of congestive heart failure is shortness of breath or swelling in the legs. In this condition, the heart struggles to pump blood effectively, which can lead to fluid buildup in the lungs (causing shortness of breath) and in the extremities, particularly the legs (resulting in swelling). This fluid accumulation can occur because the heart's decreased efficiency affects the body's ability to manage blood flow and fluid balance.

Shortness of breath can manifest as difficulty breathing during physical activity or even at rest, especially when lying down. Swelling in the legs, often referred to as peripheral edema, is a result of the body retaining fluid due to the heart's poor pumping ability. These symptoms highlight the body's response to the heart's inability to maintain adequate circulation, making them key indicators of congestive heart failure.
