Heart failure. Sounds terrifying, right? The truth is, it affects over 64 million people globally—but many don’t even know they have it until things get serious.
Now, don’t let the term fool you—it doesn’t mean your heart has stopped working altogether. It simply means the heart isn’t pumping blood as efficiently as it should. And when that happens, your body starts giving you little clues. The earlier you notice them, the better your chances of staying ahead of it.
Let’s break down some of the early warning signs your heart might be quietly sending—and what to do if you start to notice them.
You might experience:
Pay attention to:
Have a nagging, persistent cough that won’t go away? If it’s producing frothy white or pink mucus, it could be more than allergies or a cold.
This tends to get worse:
You slip on your shoes and—wait—they don’t fit? Or do your socks leave deep impressions in your ankles? This could be fluid retention, also known as 'oedema'.
Look out for swelling in:
When the heart can’t circulate blood properly, fluid seeps into surrounding tissues, leading to puffiness and discomfort.
Have you ever felt your heart racing, fluttering, or thumping like it’s doing its own thing? That’s not normal, especially if it happens often.
These are signs of an irregular heartbeat:
Your heart may be trying to compensate for its reduced efficiency, but irregular beats can increase your risk of complications.
Can't remember where you put your keys? Struggling to stay focused at work or during conversations?
Reduced blood flow from a weakened heart can affect your brain, too. Watch for:
While it might seem like stress or ageing, recurring brain fog deserves a deeper look—especially alongside other heart-related symptoms.
If you used to walk to the store or clean the house without trouble, but now it wipes you out, that’s a red flag.
You may be experiencing:
A drop in exercise tolerance is often overlooked, especially by people who chalk it up to being “just tired” or “getting older”.

Steps to take:
To sum everything up, heart failure doesn’t just hit out of nowhere—it sends signs. The trick is to tune in early.
If you're constantly tired, struggling to breathe, or noticing swelling or odd heartbeats—don’t brush it off. Your heart is the engine of your body, and like any engine, it needs maintenance and care.
You know your body best. When something feels “off”, trust that feeling. Taking one step today—whether it’s scheduling a doctor’s visit or adjusting your lifestyle—can make all the difference tomorrow.

Let’s break down some of the early warning signs your heart might be quietly sending—and what to do if you start to notice them.
1. You Can’t Catch Your Breath Like You Used To
Have you noticed you’re gasping for air after walking up a flight of stairs? Or maybe lying flat in bed makes it harder to breathe? This isn't just “getting older”—it could be dyspnoea, one of the first signs of heart failure.You might experience:
- Shortness of breath during light activity
- Difficulty breathing while lying down
- Waking up in the middle of the night, gasping for air: That tight, breathless feeling comes from fluid buildup in your lungs—a sign your heart isn't keeping up.
2. You're Always Tired—Even After Resting
Not just “I stayed up too late” tired—we’re talking about bone-deep exhaustion that hits you even after a good night’s sleep.Pay attention to:
- You feel drained after simple tasks like making your bed
- You need naps just to get through the day
- Your focus is off and your body feels heavy
- When your heart isn’t pumping efficiently, your muscles and organs don’t get the oxygen they need—and you feel it.
3. A Cough That Just Won’t Quit
This tends to get worse:
- When you lie down at night
- After physical exertion
4. Swelling That Seems to Come from Nowhere
You slip on your shoes and—wait—they don’t fit? Or do your socks leave deep impressions in your ankles? This could be fluid retention, also known as 'oedema'.
Look out for swelling in:
- Feet and ankles
- Legs
- Your belly (which may feel tight or bloated)
When the heart can’t circulate blood properly, fluid seeps into surrounding tissues, leading to puffiness and discomfort.

5. That Scary Flutter in Your Chest
These are signs of an irregular heartbeat:
- Feeling like your heart is skipping beats
- A fluttery or pounding sensation in your chest
- Racing heart for no reason
Your heart may be trying to compensate for its reduced efficiency, but irregular beats can increase your risk of complications.
6. You Feel Mentally Foggy or Off
Reduced blood flow from a weakened heart can affect your brain, too. Watch for:
- Confusion or brain fog
- Trouble concentrating
- Forgetfulness that feels unusual
While it might seem like stress or ageing, recurring brain fog deserves a deeper look—especially alongside other heart-related symptoms.
7. Your Energy for Exercise Is Gone
You may be experiencing:
- Unusual breathlessness during light activities
- Avoidance of chores or exercise you once did with ease
- Needing frequent breaks while moving around
A drop in exercise tolerance is often overlooked, especially by people who chalk it up to being “just tired” or “getting older”.
8. Bathroom Breaks All Night Long
Waking up multiple times to pee? That could be more than a hydration issue—it might point to nocturia, a sneaky sign of heart trouble.Here’s what’s happening:
- When you lie down, fluid in your legs gets reabsorbed
- Your kidneys filter it out, leading to nighttime urination
- Poor sleep adds to your fatigue and affects recovery

- Start tracking your symptoms in a notebook or app
- Book a check-up and mention what you’ve noticed
- Ask about tests like an ECG, echocardiogram, or blood work
To sum everything up, heart failure doesn’t just hit out of nowhere—it sends signs. The trick is to tune in early.
If you're constantly tired, struggling to breathe, or noticing swelling or odd heartbeats—don’t brush it off. Your heart is the engine of your body, and like any engine, it needs maintenance and care.
