Lipid is another word for fat. Cholesterol and triglycerides are types of lipid. When the concentration of lipids in your blood is too high, it is called hyperlipidaemia. Lipids are made naturally in our bodies and are also absorbed from the food we eat. If the levels of lipids are too high, the excess fat is deposited on to the walls of our blood vessels. This can lead to patches like small fatty lumps developing within the lining of some blood vessels. These patches can reduce the flow of blood, and lead to heart disease, stroke, and blood circulation problems.
