Experiencing fatigue during simple tasks such as climbing stairs, walking short distances, or carrying groceries is commonly attributed to factors like stress, aging, lack of sleep, or low fitness. However, cardiologists are cautioning that persistent fatigue during everyday activities could sometimes indicate an underlying heart issue. This is especially concerning if the exhaustion persists or intensifies over time.
One potential cause, according to doctors, could be a heart valve disorder. The heart has four valves that ensure blood flows smoothly in the right direction. If a valve becomes narrow, stiff, or leaky, the heart must exert more effort to circulate blood throughout the body. This additional strain can decrease the oxygen supply to muscles and organs, resulting in constant tiredness even with minimal exertion. Conditions like aortic stenosis and mitral regurgitation exemplify valve-related problems, where blood flow might be restricted or leak backward, impeding the heart’s efficiency.
Health specialists emphasize that fatigue associated with heart valve issues differs from the usual tiredness caused by stress or insufficient sleep. While normal fatigue may improve with rest, heart-related exhaustion typically continues after physical activity and may gradually disrupt daily life. Warning signs accompanying such fatigue include shortness of breath during light activity or when lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the feet or abdomen, and episodes of fainting or near-fainting.
Experts note that heart valve problems often go unnoticed initially, as the heart compensates by working harder. Symptoms may only become apparent during physical exertion, leading many to dismiss them as signs of aging or poor stamina. Older adults, particularly those with high blood pressure, diabetes, past heart infections, or a history of rheumatic fever, are at increased risk for valve disorders. Nonetheless, younger individuals can also develop valve issues due to congenital defects or infections.
Regular health check-ups are crucial for early detection, doctors advise. Heart valve problems might be discovered through a heart murmur during an examination, followed by diagnostic tests like echocardiograms, ECGs, stress tests, or CT scans if necessary. Treatment varies based on the condition’s severity. Mild cases may only require monitoring and lifestyle adjustments, whereas more severe instances may necessitate valve repair or replacement, including advanced minimally invasive procedures.
