A normal triglyceride level for adults is under 150 mg/dL, measured with a standard blood test. For children and teenagers between ages 10 and 19, normal is lower, under 90 mg/dL. These numbers come from a fasting blood draw, though non-fasting tests are increasingly used for routine screening.
Triglyceride Levels by Category
Triglycerides are a type of fat circulating in your blood. Your body converts calories it doesn’t need right away into triglycerides and stores them in fat cells for energy later. When you eat more calories than you burn, especially from sugary or starchy foods, triglyceride levels climb.
For adults, the standard classifications are:
- Normal: Under 150 mg/dL
- Borderline high: 150 to 199 mg/dL
- High: 200 to 499 mg/dL
- Very high: 500 mg/dL or above
Children and adolescents have a stricter threshold. A reading under 90 mg/dL is considered normal for those between ages 10 and 19. The cutoff is lower because pediatric bodies process fats differently, and elevated triglycerides during childhood can signal metabolic problems that carry into adulthood.
What Your Triglyceride Number Means
A borderline reading (150 to 199 mg/dL) usually doesn’t require medication, but it’s a signal to look at your diet, activity level, and other risk factors like cholesterol and blood sugar. Many people in this range can bring their numbers down with lifestyle changes alone.
High triglycerides (200 to 499 mg/dL) raise your risk of heart disease, particularly when combined with low HDL (“good”) cholesterol or high LDL (“bad”) cholesterol. At this level, your doctor will likely want to address other cardiovascular risk factors alongside the triglycerides themselves.
Very high triglycerides (500 mg/dL and above) create a separate, more immediate concern: pancreatitis. When triglycerides reach this level, the excess fat in the blood can inflame the pancreas, which is painful and potentially dangerous. Bringing levels below 500 mg/dL becomes a priority to prevent this.
Fasting vs. Non-Fasting Tests
Traditionally, you’d fast for 9 to 12 hours before a lipid panel so food wouldn’t temporarily spike your triglyceride reading. That’s still the gold standard for accuracy, and fasting is preferred when your doctor needs a precise measurement or is monitoring treatment for very high levels.
However, guidelines have shifted. For routine cardiovascular screening, a non-fasting blood draw is often adequate. Your triglycerides naturally rise after a meal, typically by 20 to 30 mg/dL, so a non-fasting result that comes back elevated still carries useful information. If a non-fasting test shows high triglycerides, your doctor may order a fasting follow-up to get a more precise number. For monitoring serious cases, especially if you’ve had pancreatitis linked to high triglycerides, fasting tests remain the standard.
What Raises Triglycerides
Diet is the biggest modifiable factor. Refined carbohydrates and added sugars are particularly efficient at raising triglycerides because your liver converts excess sugar directly into these fats. Sweetened beverages, white bread, pastries, and candy are common culprits. Alcohol has a similar effect. Even moderate drinking can raise triglycerides noticeably, and heavy drinking can push levels into the very high range on its own.
Beyond diet, several other factors play a role. Carrying excess weight, especially around the midsection, is closely linked to elevated triglycerides. Conditions like type 2 diabetes, hypothyroidism, and kidney disease also raise levels. Some medications, including certain blood pressure drugs, steroids, and hormone therapies, can push triglycerides up as a side effect. Genetics matter too. Some people inherit a tendency toward high triglycerides regardless of lifestyle, a condition called familial hypertriglyceridemia.
How to Lower Triglycerides
For most people with borderline or moderately high triglycerides, the approach starts with food and movement. Cutting back on added sugars and refined carbohydrates tends to produce the fastest improvement. Replacing white bread, sugary drinks, and processed snacks with whole grains, vegetables, and lean protein can drop triglycerides by 20% to 50% within a few weeks. Reducing or eliminating alcohol has a similarly outsized effect for people who drink regularly.
Regular physical activity lowers triglycerides independently of weight loss. Aerobic exercise, even moderate-intensity walking for 30 minutes most days, helps your muscles burn triglycerides for fuel. Losing weight amplifies the benefit. Even a modest loss of 5% to 10% of body weight can significantly improve your numbers.
Omega-3 fatty acids from fatty fish like salmon, mackerel, and sardines help lower triglycerides. Eating fish two or three times a week provides a meaningful dose. Prescription-strength fish oil preparations contain higher concentrations of the active fatty acids than over-the-counter supplements and are sometimes used when diet alone isn’t enough.
When Medication Is Needed
Lifestyle changes are the first line of treatment, but when triglycerides stay stubbornly high or reach the very high range, medication enters the picture. Fibrates are the most commonly prescribed drugs specifically for triglyceride reduction. They work by decreasing the liver’s production of triglyceride-rich particles and speeding up their clearance from the blood.
Statins, typically thought of as cholesterol drugs, also lower triglycerides modestly and may be recommended if you have other cardiovascular risk factors like high LDL cholesterol, diabetes, or a history of blocked arteries. In some cases, prescription omega-3 fatty acids are added alongside other medications for additional triglyceride lowering. The choice depends on how high your levels are, what other risk factors you have, and what your overall lipid profile looks like.
