How Atherosclerosis Develops: The Decades-Long Process Behind Heart Attacks and Strokes
Plaque starts in childhood and is present in most adults by midlife, even many at "low risk". Why LDL exposure adds up over decades, and why the earlier you act, the better.

Blood Pressure Explained: What the Numbers Mean and How to Measure It Properly
Heart and stroke risk rise steadily from 115/75, with no safe threshold. What the numbers and new categories mean, why nearly half of Sri Lankans with high blood pressure don't know it, and how to measure it right.

LDL, ApoB and Lipoprotein(a): Understanding Cholesterol Beyond the Basic Test

Insulin and the Metabolic Hormones: How Your Body Manages Energy
Insulin, glucagon, ghrelin, leptin and GLP-1 balance blood sugar and appetite. Two short nights cut leptin 18% and raise ghrelin 28%. How these hormones work, and how sleep, muscle and stress shift them.

Insulin Resistance: The Hidden Driver of Metabolic Ageing
Insulin resistance builds silently for years before blood sugar rises. In Sri Lanka, 23% of adults have diabetes and 30% prediabetes, but lifestyle change cut diabetes risk by 58% in a landmark trial.

Cardiovascular Risk Scores and Heart Age: What Your Numbers Add Up To
How risk scores turn blood pressure, cholesterol, smoking and diabetes into a 10-year risk, why the same numbers mean different things in different places, and what heart age tells you.

Hypertension and Longevity: Why High Blood Pressure Matters and What Lowering It Achieves
High blood pressure affects 1.28 billion adults and is often undiagnosed. What it does to the body, and why each 10 mmHg lower cuts strokes by more than a quarter.

Diabetes and Heart Disease: Why They're Linked and How to Break the Connection
Diabetes roughly doubles the risk of heart attack and stroke, but keeping five risk factors on target can remove most of that excess risk and add years of life.
