Experiencing fatigue from everyday tasks like climbing stairs, walking short distances, or carrying groceries is often attributed to stress, ageing, or inadequate sleep. However, cardiologists caution that persistent exhaustion during such activities might indicate a heart issue, particularly if it worsens over time. They point to heart valve disorders as a potential cause, where the heart’s valves, which ensure proper blood flow, may become narrowed, stiff, or leaky. This condition forces the heart to exert more effort to circulate blood, potentially leading to reduced oxygen delivery to muscles and organs, causing ongoing tiredness even with minimal physical activity.
Common conditions linked to valve issues include aortic stenosis and mitral regurgitation. In these cases, blood flow may be impeded or may leak backward, impairing the heart’s efficiency. Experts note that fatigue caused by heart valve problems is distinguishable from common fatigue due to stress or sleep deprivation, as it does not improve with rest and can progressively impact daily life. They advise being vigilant for accompanying symptoms such as shortness of breath during light activities or while lying down, chest discomfort, dizziness, irregular heartbeat, swelling in the extremities, and fainting episodes.
Specialists explain that heart valve disorders often remain undetected in their early stages because the heart compensates by working harder. Symptoms often surface during physical exertion, leading many to mistake them for signs of ageing or poor fitness. Although older adults with high blood pressure, diabetes, past heart infections, or a history of rheumatic fever are at increased risk for valve disorders, younger individuals can also be affected by congenital defects or infections.
Doctors emphasize the importance of regular health check-ups for early detection of heart valve issues. These problems might first be noticed during a physical exam if a heart murmur is detected, prompting further tests such as echocardiograms, ECGs, stress tests, or CT scans if necessary. Treatment varies depending on the condition’s severity. While mild cases might require only monitoring and lifestyle adjustments, more severe conditions could necessitate valve repair or replacement, with options including newer, less invasive procedures.
