- Lipids
- Lipids refer to different type of lipoprotein, which are cholesterol-carrying molecules in the blood. They include low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is commonly known as the ‘bad cholesterol’ because too much can cause the artery walls to harden and narrow. HDL is commonly called the ‘good cholesterol, because high levels are thought to protect against heart disease. Triglycerides, which are fats found in the bloodstream, are measured at the same time. High levels of triglycerides increase the risk of heart disease.
- Lipid profile
- Lipid profile is a set of numbers that describes levels of lipids (fats) in your blood. It includes total cholesterol, HDL, LDL and triglycerides levels.
- Lipoprotein
- Lipoprotein is a type of molecule that transports lipids (fats) like cholesterol through the blood stream. HDL and LDL are examples of lipoproteins and a good ratio between them is essential for a healthy heart.
- High-density lipoprotein (HDL)
- HDL or high-density lipoprotein is a cholesterol-carrying molecule that circulates in the blood. It’s commonly called the ‘good cholesterol’ because high levels are thought to protect against heart disease.
- Low-density lipoprotein (LDL)
- LDL or low-density lipoprotein is a cholesterol-carrying molecule in the blood. It’s commonly known as the ‘bad cholesterol’ because too much LDL is associated with atherosclerosis, where cholesterol deposits harden and narrow the artery walls. This makes it more difficult for blood to pass through.
- Lower esophageal sphincter (LES)
- Lower esophageal sphincter (LES) is a circular band of muscle that separates the esophagus and the stomach. If the LES doesn't stay taut, stomach acid can leak back into the esophagus, causing heartburn or acid reflux.
