Lipid metabolism disorder refers to a group of conditions characterized by abnormalities in the synthesis, transport, or degradation of lipids (fats) in the body. These disorders can lead to elevated or reduced levels of cholesterol, triglycerides, or lipoproteins, increasing the risk of cardiovascular diseases, pancreatitis, and other systemic complications. They can be primary (genetic) or secondary (due to lifestyle, diet, or other medical conditions).
