What is a common symptom of congestive heart failure?

Shortness of breath is a hallmark symptom of congestive heart failure (CHF) due to the heart's inability to pump blood effectively. This inefficiency causes fluid to back up in the lungs, leading to a condition known as pulmonary congestion. As fluid accumulates, individuals may experience difficulty breathing, especially during physical activity or while lying flat, which can lead to a feeling of breathlessness or "air hunger." CHF can also cause a range of other symptoms due to the body's inadequate circulation, making shortness of breath a crucial indicator for healthcare professionals to monitor in patients suspected of having this condition.
