If you’ve ever brushed off persistent fatigue as a byproduct of a busy life, you might want to think again. Cardiologist Dr James Wetherby has sounded the alarm on a hidden danger behind the common complaint of feeling ‘tired all the time’.
New research reveals that this seemingly harmless symptom could actually signal the onset of heart failure. This condition affects over 900,000 people in the UK alone and is often diagnosed too late.
Ignoring your exhaustion could be putting your health at serious risk. Here’s what you need to know to spot the warning signs early.
Silent danger of heart failure
Heart failure occurs when the heart struggles to pump blood effectively, leading to poor oxygenation and circulation in the body. Dr James Wetherby explains: “One of the earliest and most overlooked symptoms of heart failure is persistent fatigue.
“When your heart is under strain, it struggles to deliver oxygen-rich blood to the muscles and tissues, leaving you feeling utterly drained.” While symptoms like chest pain or shortness of breath are more obvious indicators of heart issues, fatigue often flies under the radar.
Research from the British Heart Foundation reveals that up to 40% of people with heart failure were initially diagnosed late, in part because they mistook their symptoms for everyday exhaustion.
Spotting the warning signs
More than 780,000 people in the UK are on their GP’s heart failure register
Fatigue is just one piece of the puzzle. Here are other subtle symptoms that could indicate heart failure:
- Shortness of breath – especially during routine activities or when lying down.
- Swelling in the legs, ankles or feet – caused by fluid retention due to the heart’s reduced pumping ability.
- Unexplained weight gain – another result of fluid buildup.
- Difficulty concentrating or confusion – a sign that your brain isn’t receiving enough oxygen.
If you notice a combination of these symptoms alongside ongoing fatigue, it’s time to consult your GP.
What can you do?
Taking proactive steps can significantly reduce your risk of developing or worsening heart failure.
- Get Active: Incorporate at least 30 minutes of moderate exercise into your day. Even activities like brisk walking can improve cardiovascular health.
- Eat Heart-Healthy Foods: Reduce your intake of saturated fats and processed sugars. Focus on a Mediterranean-style diet rich in fruits, vegetables, whole grains, and lean proteins.
- Prioritise Sleep: Poor sleep has been linked to higher rates of heart disease. Aim for 7–9 hours of quality rest each night.
- Know Your Numbers: Regularly monitor your blood pressure, cholesterol, and weight to catch potential issues early.
- Act on Symptoms: Don’t ignore unusual tiredness, swelling, or breathlessness. Seek medical advice promptly.
Why this matters now
Health and wellness specialists from Ski Famille note that rising awareness is critical, particularly as more people adopt desk-based jobs and less active lifestyles. “People often assume fatigue is normal because it’s so common,” a spokesperson said. “But understanding the root cause is key to addressing it—and potentially preventing life-threatening complications like heart failure.”
This information is especially relevant in the colder months when people tend to neglect physical activity and eat heavier comfort foods. These factors can exacerbate underlying heart issues without immediate symptoms, making it crucial to stay vigilant. For more information, visit the NHS website.
