Experiencing fatigue during simple activities like climbing stairs or carrying groceries is commonly attributed to stress, aging, or lack of sleep. However, cardiologists caution that persistent tiredness during routine tasks might indicate an underlying heart issue, particularly if the fatigue worsens over time. One potential cause is a heart valve disorder, where the heart’s four valves, responsible for directing blood flow, become narrow, stiff, or leaky. This condition forces the heart to exert extra effort to circulate blood, resulting in reduced oxygen supply to muscles and organs, and consequently, constant tiredness even with minimal activity.
Heart valve issues such as aortic stenosis and mitral regurgitation exemplify how restricted or backward blood flow can impair heart function. Health experts emphasize that fatigue related to valve disorders differs from normal tiredness due to stress or insufficient sleep. Unlike regular fatigue, which improves with rest, heart-related fatigue persists after physical exertion and may gradually impact daily activities. Additional warning signs accompanying fatigue include shortness of breath during light activity or while lying down, chest discomfort, dizziness, irregular heartbeat, and swelling in the feet, ankles, or abdomen. Fainting or near-fainting episodes are also potential indicators.
Specialists note that heart valve problems often remain undetected in their early stages because the heart compensates by working harder. Symptoms typically emerge during physical exertion, leading many to mistakenly attribute them to aging or poor stamina. Older adults, particularly those with high blood pressure, diabetes, past heart infections, or a history of rheumatic fever, face an elevated risk of valve disorders. Nonetheless, younger individuals can also develop valve issues due to congenital defects or infections.
Doctors advocate for regular health check-ups to facilitate early detection of heart valve problems. These conditions might initially be identified through a heart murmur during an examination, followed by diagnostic tests such as echocardiograms, ECGs, stress tests, or CT scans if necessary. The treatment approach varies depending on the severity of the condition. While mild cases may only necessitate monitoring and lifestyle adjustments, more severe instances could require valve repair or replacement, including advanced minimally invasive procedures.
