The NHS says it may be more noticeable as the day goes on
Heart failure, despite affecting over a million people in the UK, is notoriously unpredictable. The condition arises when the heart can’t pump blood effectively, leading to insufficient oxygen circulation, often due to the heart becoming weak or stiff.
Contrary to common belief, this doesn’t mean the heart has “stopped working”. It could stem from a heart attack, cardiomyopathy, or even high blood pressure, which increases risk.
The British Heart Foundation highlights that 80% of heart failure cases in England are diagnosed in hospitals, with almost half (40%) presenting symptoms that should have prompted earlier assessment. One symptom, less obvious in the morning but more apparent as the day progresses, might surprise you – it’s in your feet.

The NHS states that swollen ankles and legs, due to fluid build-up known as oedema, are among the most common indicators of heart failure. “It may be better in the morning and get worse later in the day,” notes the health service.
If you notice that one or both of your ankles, feet, or legs are swollen and the swelling doesn’t subside after a few days or worsens, you should contact your GP. While oedema isn’t exclusively a sign of heart disease – it could be something less severe like a sprain or insect bite – it could also indicate a blood clot or infection, as previously reported.
So, it’s important to keep an eye on the situation and seek medical help if it continues. Oedema can also result from standing or sitting for too long, being overweight or pregnant, or taking certain medications such as steroids or antidepressants.
Hence, the NHS suggests trying ‘gentle exercises’ and elevating the swollen area when possible before consulting a doctor. The symptoms of heart failure can differ from person to person and may start suddenly or ‘develop gradually’ over weeks or even months.
Other warning signs to look out for include:
- Breathlessness. This may occur after activity or whilst you’re resting. It will probably be worse whilst lying down.
- Fatigue
- Feeling light headed
- Fainting
Less common symptoms such as depression, anxiety, wheezing, and loss of appetite may also be experienced. Again, if you’re experiencing worsening or persistent symptoms – contact your GP.
