12. Fatigue and Weakness
Fatigue and weakness are among the most disabling symptoms of heart failure. Because the heart cannot pump enough blood, less oxygen and nutrients reach the body’s muscles and organs. This makes even simple tasks — like brushing teeth, dressing, or cooking — feel exhausting.
Unlike normal tiredness, this fatigue does not improve much with rest. Patients often say they feel like their “body battery is always low.” This symptom can be frustrating, as it limits independence and affects quality of life.
For instance, Mrs. Christi, a 70-year-old homemaker, noticed that she became unusually tired after doing basic chores like cutting vegetables or sweeping the floor. At first, her family assumed it was normal aging. But when she began feeling breathless along with fatigue, they took her to a doctor. Tests confirmed she had heart failure. With treatment and light activity plans, her energy levels improved, although she still had to pace herself.
Fatigue also affects emotional health. Patients may feel guilty about depending on family or may withdraw from social activities. For caregivers, it is important to understand that this tiredness is not laziness — it is a real and serious medical symptom. With proper care, patients can find ways to conserve energy and still enjoy meaningful activities.
