Cholesterol is a waxy substance similar to fat that circulates in the bloodstream. Your body requires cholesterol to build healthy cells and produce certain hormones. However, when cholesterol levels become too high, it can raise the risk of heart disease.There are two primary types of cholesterol. Low-density lipoprotein (LDL) is commonly known as “bad” cholesterol because high levels can lead to plaque buildup in the arteries. High-density lipoprotein (HDL) is often called “good” cholesterol because it helps remove excess cholesterol from the bloodstream. When LDL levels become elevated, fatty deposits can collect inside artery walls, narrowing them and increasing the chance of heart attacks or strokes.
Why High Cholesterol Is a Serious Health Concern

High cholesterol is one of the major contributors to cardiovascular disease, including heart atta:cks, coronary artery disease, and strokes. When LDL cholesterol builds up in the arteries, it forms plaque that gradually narrows the blood vessels and restricts blood flow.This condition, called atherosclerosis, can limit oxygen-rich bl00d reaching the heart and other organs. Over time, this restriction increases the risk of serious health complications. Elevated cholesterol levels are also often linked with other conditions such as high blood pressure and diabetes, which further raise the risk of heart problems.
