Atherosclerosis — When the Highways of Life Start to Harden

How high sugar, lipids, and inflammation roughen artery walls and build plaques — slowly, silently, and fixably.

Your arteries aren’t just tubes; they’re dynamic highways lined with living cells that expand, contract, and repair themselves daily. But constant exposure to high sugar, fat, and inflammation slowly roughens their smooth walls, turning them from flexible asphalt to cracked concrete. That’s atherosclerosis — the slow, quiet sculptor of heart attacks and strokes.

The story begins when excess glucose and oxidised cholesterol damage the inner lining (the endothelium). Tiny cracks appear. The immune system rushes in to patch them, sending macrophages to gobble up debris. But instead of fixing the wound, the macrophages get stuck, stuffed with fat, forming foam cells — the first step in plaque formation. Calcium and fibrous tissue build over the site, narrowing the vessel. Blood flow slows, pressure rises, and oxygen delivery drops.

Over time, these plaques can rupture, spilling clot-triggering material into the bloodstream. A single clot can block a coronary artery, starving the heart — a heart attack. Or it can travel to the brain — a stroke. It’s not sudden; it’s years of silent corrosion reaching its breaking point.

Yet the disease is surprisingly reversible in early stages. Lowering sugar and LDL, increasing movement, and eating fibre-rich foods all calm inflammation and even shrink plaques. The arteries remember how to heal — they just need peace and better materials.

Why It Matters

Atherosclerosis isn’t just about cholesterol; it’s about chronic irritation. The chemistry of your blood literally sculpts your vessels — for better or worse.
