Unusual fatigue during everyday activities like climbing stairs or carrying groceries may sometimes be a sign of an underlying heart issue, cardiologists caution. While such tiredness is often attributed to stress, aging, or lack of sleep, persistent or worsening fatigue could point to a heart valve disorder. The heart’s four valves ensure blood flows smoothly in the right direction, but if one becomes narrow, stiff, or leaky, the heart must work harder to circulate blood, potentially reducing oxygen supply to muscles and organs. This extra effort can result in constant tiredness even after minimal exertion.
Conditions such as aortic stenosis and mitral regurgitation epitomize valve-related problems where blood flow can become restricted or leak backward, impairing the heart’s efficiency. Health experts distinguish fatigue linked to heart valve issues from usual tiredness caused by stress or poor sleep. Unlike regular fatigue that typically improves with rest, heart-related fatigue may persist after physical activity and gradually disrupt daily life. Other warning signs accompanying fatigue may include shortness of breath during light activity or while lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the extremities, and fainting episodes.
Specialists note that heart valve problems often remain unnoticed in their early stages as the heart compensates by working harder. Symptoms usually emerge during physical exertion, leading many to mistake them for signs of aging or poor stamina. While older adults with high blood pressure, diabetes, past heart infections, or a history of rheumatic fever are at higher risk, younger individuals can also be affected due to congenital defects or infections.
Regular health check-ups are crucial for early detection, doctors advise. Sometimes heart valve issues are identified through a heart murmur during an examination, prompting further tests such as echocardiograms, ECGs, stress tests, or CT scans if necessary. Treatment varies with the severity of the condition; mild cases might only require monitoring and lifestyle adjustments, whereas more serious cases could necessitate valve repair or replacement procedures, including newer minimally invasive options.
