Unusual fatigue during everyday tasks such as climbing stairs, walking short distances, or carrying groceries might be more than just a sign of stress, ageing, or poor sleep. Cardiologists caution that persistent tiredness could indicate an underlying heart issue, particularly if it worsens over time. One potential culprit is a heart valve disorder, where a valve becomes narrow, stiff, or leaky, forcing the heart to exert more effort to circulate blood efficiently. This increased workload can result in reduced oxygen supply to muscles and organs, leading to constant fatigue even after minimal physical activity.
Heart valve conditions like aortic stenosis and mitral regurgitation exemplify these issues. In such cases, blood flow may be restricted or leak backward, impairing the heart’s function. Health experts differentiate heart valve-related fatigue from typical tiredness due to stress or lack of sleep. While normal fatigue often improves with rest, fatigue stemming from heart issues may persist after exertion and progressively disrupt daily routines. Alongside fatigue, individuals should be alert to symptoms such as shortness of breath during light activities or while lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the lower extremities, and fainting episodes.
Heart valve disorders frequently go unnoticed initially, as the heart compensates by working harder until symptoms emerge, often during physical exertion. This can lead many to misattribute symptoms to ageing or poor fitness. Older adults, particularly those with high blood pressure, diabetes, previous heart infections, or a history of rheumatic fever, face higher risks of valve problems. Nevertheless, younger individuals can also develop these issues due to congenital defects or infections. Regular health check-ups are crucial for early detection, and heart valve problems can sometimes be identified through a heart murmur during routine examinations.
If a heart valve disorder is suspected, doctors may conduct tests such as echocardiograms, ECGs, stress tests, or CT scans. Treatment strategies vary based on the condition’s severity. While mild cases might only require monitoring and lifestyle modifications, more significant issues may necessitate valve repair or replacement. Advances in medical technology have introduced minimally invasive procedures, providing patients with less traumatic treatment options.
