Triglycerides (TGs) are a type of fat in your body. They store energy and play many important roles in your body. TGs are one of the fats (or lipids) that are measured when you have a cholesterol test.
TGs are important, but too much of them in your body can be harmful. When TGs build up, they can lead to weight gain and obesity. TG can build-up in your organs, such as your heart. It can make it hard for the organs to work normally. This is why your doctor tests your blood lipid levels regularly. Talk to your doctor about how you can improve your lipid levels.
