Heart failure reduces your heart’s pumping ability so less blood reaches your muscles. This lack of oxygen and nourishment causes your muscles to get tired much more quickly.
In addition, the reduced pumping ability results in congestion in the lungs which in turn causes shortness of breath. Some patients find it difficult to distinguish between tiredness/fatigue and shortness of breath. Increasing tiredness on effort or during activity is more likely related to heart failure.
You may be able to reduce how tired you get by exercising. Moderate exercise and exercise training may help improve your symptoms. In contrast to what many people believe, exercise is considered beneficial in patients with heart failure. Exercise also reduces stress and boosts your energy levels.
