Swelling
When heart failure occurs, blood cannot be pumped forward by the heart. As a result, it would back up in your systemic veins and leak out into other tissues. This leads to the buildup of excess fluids in the body tissues, a condition also known as edema. You might easily notice swelling in different parts of the body, such as the legs, ankles, feet, or abdomen. In many cases, the weight of your body might also increase unexpectedly as a result. [2]
