Blood lipids, including total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides, are essential for our bodies. However, an imbalance of these lipids can lead to health problems such as atherosclerosis, which can cause heart attacks, strokes, and other cardiovascular diseases. To understand blood lipids and their impact on our health, it is crucial to know how to interpret blood lipid test results and take appropriate measures to maintain a healthy balance of these lipids. A healthy diet, regular exercise, and, if necessary, medication can help control blood lipids and reduce the risk of cardiovascular diseases.
