What are triglycerides?
Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals. If you regularly eat more calories than you burn, particularly “easy” calories like carbohydrates and fats, you may have high triglycerides (hypertriglyceridemia).
What’s considered normal?
A simple blood test can reveal whether your triglycerides fall into a healthy range.
- Normal — Less than 150 milligrams per deciliter (mg/dL), or less than 1.7 millimoles per liter (mmol/L)
- Borderline high — 150 to 199 mg/dL (1.8 to 2.2 mmol/L)
- High — 200 to 499 mg/dL (2.3 to 5.6 mmol/L)
- Very high — 500 mg/dL or above (5.7 mmol/L or above)
What’s the difference between triglycerides and cholesterol?
Triglycerides and cholesterol are separate types of lipids that circulate in your blood. Triglycerides store unused calories and provide your body with energy, and cholesterol is used to build cells and certain hormones. Because triglycerides and cholesterol can’t dissolve in blood, they circulate throughout your body with the help of proteins that transport the lipids (lipoproteins).
