When it comes to looking after your heart and reducing your risk of heart disease, it's helpful to know your numbers. These markers—like blood pressure, cholesterol, HbA1c, and waist measurement—offer a helpful snapshot of how well your heart and blood vessels are doing. Knowing your numbers puts you in a stronger position to make informed choices and take positive steps towards better health, one small change at a time. Let’s explore what these numbers mean, why they matter, and how you can begin to manage them.
1. Blood Pressure: The Silent Indicator
📍 What it is: The force of your blood pressing against the walls of your arteries.
📊 Ideal number: Around 120/80 mmHg
📉 Why it matters: High blood pressure (also known as hypertension) can quietly cause damage over time. It’s a major risk factor for heart disease, stroke, and kidney issues—often without any warning signs.
💡 How to manage it:
- Use less salt in cooking
- Stay active in a way that feels good to you
- Find simple ways to reduce stress- Aim for a healthy weight
- Follow medical advice if medication is needed
2. Cholesterol: Finding the Right Balance
📍 What it is: A waxy, fat-like substance in your blood. Your body needs some cholesterol, but too much of the wrong kind can be harmful.
🩺 Key markers to know:
- Total cholesterol: ideally under 5 mmol/L
- LDL (bad) cholesterol: ideally under 3 mmol/L
- HDL (good) cholesterol: above 1.2 mmol/L (women) / 1.0 mmol/L (men)
- Triglycerides: ideally under 1.7 mmol/L
📉 Why it matters: If there’s too much LDL cholesterol in your blood, it can build up in your arteries and make them narrower—raising your risk of heart attacks or strokes.
💡 How to manage it:
- Choose heart-friendly fats (like olive oil, avocado, nuts, and seeds)- Eat more fibre-rich foods such as oats, lentils, fruit, and veg- Reduce processed and fried foods- Get moving in ways you enjoy—walking, dancing, gardening all count
3. HbA1c: Your Blood Sugar Snapshot
📍 What it is: A blood test that shows your average blood sugar levels over the past two to three months.
📊 Healthy range:
- Under 42 mmol/mol (for those without diabetes)
- 42–47 mmol/mol may suggest prediabetes
- 48 mmol/mol or above indicates diabetes
📉 Why it matters: Raised blood sugar over time can damage blood vessels and increase the risk of heart disease, stroke, and circulation issues.
💡 How to manage it:
- Choose wholegrain options over refined carbs
- Be mindful of portions and sugary snacks
- Find regular movement that fits into your day
- Work on steady, realistic eating habits—nothing extreme
4. Waist Measurement: A Simple but Powerful Indicator
📍 What it is: A measure of abdominal fat, taken around your waist (just above your hip bones).
📏 Healthy range:
- Women: Less than 80 cm (about 31.5 inches)
- Men: Less than 94 cm (about 37 inches)
📉 Why it matters: Carrying more weight around your middle—especially if it’s deep, visceral fat—can raise your risk of heart disease, type 2 diabetes, and stroke. Even if your weight seems “normal,” a higher waist measurement may still signal increased risk.
💡 How to manage it:
- Aim for balanced meals with plenty of fibre and lean protein
- Limit sugary drinks and snacks
- Build more movement into your day, even in short bursts
- Prioritise good sleep and stress management—both can influence belly fat
