What Are Triglycerides?
Triglycerides are a type of fat (lipid) found in your bloodstream. After you eat, your body converts any excess calories it doesn't immediately need into triglycerides, which are stored in fat cells. Between meals, hormones release these triglycerides to provide energy.
Consistently consuming more calories than your body uses—especially from refined carbohydrates, sugars, and fats—can lead to elevated triglyceride levels. High triglycerides are a key marker of metabolic health and may raise your risk of heart disease, stroke, pancreatitis, and other cardiovascular problems.
Why Are Triglycerides Important?
Triglyceride levels are measured as part of a lipid panel, which also includes total cholesterol, HDL (“good”) cholesterol, and LDL (“bad”) cholesterol. This test is used to:
-
Assess your risk of heart disease and stroke
-
Monitor ongoing treatment for high lipid levels
-
Track progress after a heart attack or cardiac event
-
Guide lifestyle or medication-based interventions
Your healthcare provider will interpret your triglyceride results in combination with other cardiovascular risk factors, such as blood pressure, smoking status, age, blood sugar levels, and family history.
What Causes High Triglycerides?
High triglyceride levels may be caused by:
-
Overeating, especially refined carbs or sugary foods
-
Obesity or being overweight
-
Sedentary lifestyle
-
Excess alcohol intake
-
Uncontrolled diabetes or insulin resistance
-
Hypothyroidism
-
Certain medications (e.g., corticosteroids, beta blockers, diuretics, antipsychotics)
-
Genetic lipid disorders (such as familial hypertriglyceridemia)
Some people may have high triglycerides due to inherited conditions, even if they maintain a healthy lifestyle.
Who Should Get Tested?
Cholesterol and triglyceride testing is recommended at least every 4 to 6 years for people with no known risk factors, and more frequently for those who have any of the following:
-
Smoking
-
Obesity or excess weight
-
Poor diet
-
Physical inactivity
-
High blood pressure
-
Age ≥45 (men) or ≥55 (women)
-
Family history of heart disease
-
Type 2 diabetes or prediabetes
-
Previous heart attack or cardiovascular disease
Note: Traditionally, triglyceride levels are measured after fasting for 9–12 hours, but non-fasting tests are now also considered reliable in many cases. Your doctor will advise you on which test is appropriate.
Triglyceride Test Results: What Do They Mean?
Triglyceride levels are measured in milligrams per deciliter (mg/dL). Here’s how to interpret the results by age group:
Adults (Age 20 and older):
| Triglyceride Level (mg/dL) | Category |
|---|---|
| <150 | Normal (Low risk) |
| 150–199 | Borderline high |
| 200–499 | High |
| ≥500 | Very high (Increased risk, pancreatitis risk) |
Children (Newborn to 9 years):
| Triglyceride Level (mg/dL) | Category |
|---|---|
| <75 | Normal (Low risk) |
| 75–99 | Borderline high |
| ≥100 | High |
Youth (Ages 10–19):
| Triglyceride Level (mg/dL) | Category |
|---|---|
| <90 | Normal (Low risk) |
| 90–129 | Borderline high |
| ≥130 | High |
How to Lower Triglyceride Levels
If your triglycerides are high, your doctor may recommend one or more of the following treatments:
Lifestyle Changes
-
Adopt a heart-healthy diet: Focus on whole grains, lean proteins, vegetables, and healthy fats (like omega-3s).
-
Limit sugar and refined carbs: These rapidly convert to triglycerides.
-
Increase physical activity: Aim for at least 150 minutes of moderate exercise per week.
-
Lose excess weight: Even modest weight loss can significantly lower triglycerides.
-
Avoid alcohol: Especially if levels are very high.
Medications (if needed)
-
Statins
-
Fibrates
-
Niacin
-
Prescription-strength omega-3 fatty acids
Your healthcare provider will help you develop a personalized treatment plan based on your overall cardiovascular risk profile.
Final Thoughts
Triglycerides are a vital indicator of your heart health. Elevated levels may not cause symptoms, but over time they can contribute to atherosclerosis, pancreatitis, and cardiovascular disease. Regular screening, healthy lifestyle habits, and early intervention are key to maintaining optimal triglyceride levels and reducing long-term health risks.
