Feeling unusually tired during everyday tasks such as climbing stairs, walking short distances, or carrying groceries might be more than just stress, ageing, or a lack of fitness. Cardiologists caution that persistent fatigue in these situations could indicate a heart problem, particularly if it worsens over time. One potential cause is a heart valve disorder, where the heart’s valves, which ensure blood flows correctly, become narrowed, stiff, or leaky. This forces the heart to work harder, causing reduced oxygen supply to muscles and organs, and resulting in a constant sense of exhaustion even after minimal exertion.
Heart valve issues, such as aortic stenosis and mitral regurgitation, are common examples where blood flow is either restricted or leaks backward, impairing the heart’s efficiency. Unlike normal tiredness from stress or lack of sleep, fatigue related to heart valve problems doesn’t improve with rest and can gradually impact daily life. Physicians advise looking out for accompanying warning signs like shortness of breath during light activity or when lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the extremities, and fainting episodes.
Heart valve problems are often subtle in the early stages because the heart compensates by working harder, leading many to dismiss symptoms as normal ageing or poor stamina. However, these issues tend to become noticeable during physical exertion. Risk factors include older age, high blood pressure, diabetes, past heart infections, or a history of rheumatic fever, though younger individuals may also be affected due to congenital defects or infections.
Early detection through regular health check-ups is crucial. Heart valve problems can sometimes be identified by a heart murmur during a physical examination, with further testing like echocardiograms, ECGs, stress tests, or CT scans used to confirm the diagnosis. Treatment varies with severity; mild cases might only need monitoring and lifestyle adjustments, while more serious conditions could require valve repair or replacement, with options available for minimally invasive procedures.
