Understanding Cholesterol and Heart Health

Cholesterol is not a poison — it is essential for building cells and hormones. The problem arises when certain cholesterol particles circulate in excess for years, depositing in artery walls and narrowing them. This process, called atherosclerosis, begins silently in our 20s and 30s and is the root cause of most heart attacks and strokes.

Reading your lipid report

• LDL ('bad' cholesterol): the main driver of artery blockage — lower is better
• HDL ('good' cholesterol): protective — higher is better
• Triglycerides: blood fats that rise with sugar intake, alcohol and excess weight
• Total cholesterol: a summary number — less important on its own than the parts

Why one number is not the whole story

Whether your cholesterol needs treatment depends on your overall cardiovascular risk — your age, blood pressure, sugar status, smoking, and family history of early heart disease. The same LDL value may be acceptable in a healthy 25-year-old but need active treatment in someone with diabetes. This is why lipid reports are best interpreted by a physician, not in isolation.

What genuinely helps

• Replacing fried and processed food with whole grains, pulses, vegetables and nuts
• At least 30 minutes of brisk walking or equivalent activity most days
• Maintaining a healthy waist size and body weight
• Avoiding tobacco completely and limiting alcohol
• Managing blood sugar and blood pressure alongside

Do I need medicines?

For many people with moderately high cholesterol and low overall risk, structured lifestyle change is the first step, with a repeat test after a few months. When cholesterol is very high, or overall risk is significant (for example in diabetes or after a heart event), medicines such as statins are recommended — they are among the most well-studied and effective preventive treatments in modern medicine.

If your last lipid profile is more than a year or two old — or you have never had one — consider getting tested and reviewed.
