Heart Failure: Less Common Symptoms - Topic Overview

While there are certain symptoms that people with heart failure experience more commonly, there are many other symptoms that heart failure can cause. These symptoms are typically less common because they often result from more severe heart failure, when the body can no longer compensate properly for the failing heart.

The first table summarizes congestive symptoms that result from fluid leaking into the lungs and the rest of the body. The second table summarizes symptoms that occur because the heart can no longer pump enough blood to meet the body's needs, which causes poor blood circulation. After the tables is a more detailed explanation of each symptom.

Tell your doctor if you experience any of these less common symptoms.
