Weight Gain
Another common sign of heart failure is unexpected weight gain. When your heart does not work properly, blood will build up and lead to the retention of fluids and salt around the body. Therefore, you might notice an increase of several pounds over the course of one or two days. Keep in mind that this is a bad symptom that indicates the worsening of your heart failure. Therefore, make sure to keep track of the body weight and seek medical support as soon as possible to prevent further complications. [5]
