How Do High Blood Lipids and High Blood Sugar Harm Blood Vessels?

High blood lipids and high blood sugar can negatively impact blood vessels in different ways.

1) Blood lipids

which include cholesterol and triglycerides, circulate in the bloodstream. Imagine a water pipe representing blood vessels, with small particles sticking to its inner walls—these particles symbolize cholesterol and triglycerides. When their levels are too high, they are more likely to adhere to blood vessel walls, particularly in smaller vessels. Over time, as more lipids accumulate, the vessel narrows, restricting blood flow. If this occurs in the heart, it may lead to heart disease; if it happens in the brain, it could result in a stroke.

2) High blood sugar

on the other hand, can trigger inflammation in blood vessels, causing them to stiffen. Healthy blood vessels are flexible, similar to a rubber band, but inflammation can make them lose elasticity, much like an old rubber band that has become brittle. Stiffened blood vessels are more vulnerable to damage, particularly if blood pressure is also high.

When a vessel sustains damage, the body works to repair it, forming scar tissue. This scarring can contribute to blockages, and in severe cases, a rupture may lead to bleeding in the heart or brain.

Maintaining healthy blood lipid and blood sugar levels plays an essential role in supporting vascular health.
