Triglycerides are a type of fat in your blood. They come from food and are also made by your liver, especially from extra calories, sugar and alcohol. Your body stores them for energy. Triglycerides are part of a lipid profile (lipid panel in the US). Because they rise after eating, your doctor may sometimes ask you to fast before the test.
Why is this test done?
- As part of a cholesterol test
- To assess heart disease risk
- If you have diabetes or pancreatitis
- To monitor treatment
What does a high triglycerides mean?
High triglycerides are linked to a higher risk of heart disease, and very high levels can cause inflammation of the pancreas (pancreatitis).
Possible reasons include:
- Eating shortly before the test
- Alcohol
- Being overweight
- Type 2 diabetes, especially if not well controlled
- Diets high in sugar and refined carbohydrates
- An underactive thyroid, kidney disease and some medicines
- Inherited conditions
What does a low triglycerides mean?
Low triglycerides are not usually a concern.
Possible reasons include:
- A low-fat diet
- Some medicines
- Rarely, an overactive thyroid or malabsorption
Why we don't list a "normal range". Reference ranges differ between laboratories and can depend on your age, sex and whether you are pregnant. The range printed next to your result on your own report is the one that applies to you, so use that, and talk to your doctor about what your result means for you.
What can affect your triglycerides result?
- Eating or drinking alcohol before the test
- Recent illness
- Pregnancy
- Medicines, such as steroids, some contraceptives and some HIV medicines

Frequently asked questions
Do I need to fast for a triglycerides test?
Not always. Many tests are done without fasting, but if your triglycerides are high your doctor may ask for a repeat test after fasting overnight.
Does alcohol raise triglycerides?
Yes. Alcohol is a common cause of high triglycerides, and cutting down can lower them noticeably.
Are triglycerides the same as cholesterol?
No. Both are fats in the blood and are measured in the same lipid profile, but triglycerides store energy while cholesterol is used to build cells and hormones.
