Your heart is one of the hardest-working organs in your body, tirelessly pumping blood to keep you alive and healthy. Let’s take a moment to understand how this vital organ functions, how to keep it healthy, and what signs to watch out for if something isn’t right.
Why Your Heart Matters
The heart is a muscular organ about the size of your fist, located slightly left of the centre of your chest. It beats around 100,000 times a day, pumping blood to supply oxygen and nutrients to every part of your body while removing waste products.
A healthy heart ensures:
Smooth circulation of blood
Proper oxygen supply to organs
Strong immunity and energy levels
Long-term well-being
When the heart isn’t functioning properly, it can lead to heart disease, which remains the leading cause of death worldwide. The good news? Many heart conditions are preventable with the right care.
Common Heart Conditions & Their Symptoms
Heart diseases can develop silently, so recognising early signs is crucial:
1. Coronary Artery Disease (CAD)
Cause: Blocked arteries due to cholesterol buildup.
Symptoms: Chest pain (angina), shortness of breath, fatigue.
2. Heart Attack (Myocardial Infarction)
Cause: Sudden blockage of blood flow to the heart.
Symptoms:
Severe chest pain (like pressure or squeezing)
Pain spreading to the arm, neck, or jaw
Cold sweat, nausea, dizziness
3. Heart Failure
Cause: Weakened heart unable to pump efficiently.
Symptoms:
Swelling in legs/ankles
Persistent fatigue
Rapid or irregular heartbeat
4. Arrhythmia (Irregular Heartbeat)
Cause: Electrical signals in the heart misfire.
Symptoms:
Palpitations (fluttering sensation)
Dizziness or fainting
Shortness of breath
If you experience any of these symptoms, consult a doctor immediately. Early detection can save lives.

Lack of Exercise – A Sedentary lifestyle weakens the heart.
Smoking & Alcohol – Damages blood vessels.

Obesity – Excess weight strains the heart.
Non-Modifiable (Cannot Be Changed)
Age – Risk increases after 45 (men) or 55 (women).
Family History – Genetic predisposition.

How to Keep Your Heart Healthy
Small changes can make a big difference!
