Cardiologists are cautioning that persistent fatigue during routine activities such as climbing stairs or carrying groceries might be a sign of an underlying heart condition rather than just stress or ageing. This type of tiredness, especially when it worsens over time, could be linked to heart valve disorders. The heart relies on four valves to maintain proper blood flow direction; when these valves narrow, stiffen, or leak, the heart must exert extra effort to circulate blood effectively. Such conditions can limit oxygen delivery to muscles and organs, resulting in constant fatigue even with minimal exertion.
Common heart valve-related ailments include aortic stenosis and mitral regurgitation, where blood flow can become restricted or leak backward, hindering the heart’s efficiency. Unlike regular fatigue from stress or poor sleep, fatigue stemming from heart valve issues might persist after physical activity and start to disrupt daily life. Accompanying signs such as shortness of breath, chest discomfort, dizziness, irregular heartbeat, or swelling in the feet and abdomen should not be overlooked.
Specialists emphasize that heart valve conditions often go undetected initially because the heart compensates by working harder, with symptoms only emerging during physical exertion. This can lead many to dismiss these warning signs as natural ageing or lack of fitness. Older adults face a higher risk, particularly if they have high blood pressure, diabetes, a history of heart infections, or rheumatic fever, though congenital defects or infections can also affect younger individuals.
Routine health examinations play a crucial role in the early identification of heart valve issues. A heart murmur detected during a check-up might prompt further tests such as echocardiograms, ECGs, stress tests, or CT scans to confirm the condition. Treatment varies with the severity of the disorder; while mild cases might only necessitate monitoring and lifestyle adjustments, more severe cases could require valve repair or replacement, including advanced minimally invasive procedures.
