Exhaustion from everyday activities like climbing stairs or carrying groceries is often attributed to stress, aging, or poor fitness. However, cardiologists caution that persistent fatigue during such tasks may signal an underlying heart condition, particularly a heart valve disorder. The heart’s valves ensure blood flows in the right direction, and when they become narrow, stiff, or leaky, the heart must work harder, potentially reducing oxygen supply to muscles and leading to constant tiredness.
Common valve-related issues include aortic stenosis and mitral regurgitation, where blood flow is restricted or leaks backward, compromising the heart’s efficiency. Unlike fatigue from stress or lack of sleep, which typically improves with rest, heart-related fatigue persists after activity and can gradually disrupt daily life. This type of fatigue may also be accompanied by symptoms such as shortness of breath, chest discomfort, dizziness, irregular heartbeat, swelling, or fainting.
Experts note that heart valve problems can initially go unnoticed as the heart compensates by working harder, with symptoms often surfacing only during physical exertion. This leads many to mistakenly attribute them to normal aging or poor stamina. The risk of valve disorders is higher in older adults, particularly those with high blood pressure, diabetes, or a history of heart infections or rheumatic fever. However, younger individuals are not immune, as congenital defects or infections can also cause valve issues.
Doctors emphasize the importance of regular health check-ups for early detection of heart valve problems. These issues can sometimes be identified by a heart murmur during an examination and further assessed with tests like echocardiograms, ECGs, stress tests, or CT scans. Treatment varies with severity; mild cases might only need monitoring and lifestyle adjustments, while more severe cases could require valve repair or replacement, including minimally invasive procedures.
