Learn about triglycerides, their normal range, and what your levels mean for your health.

Aug 1, 2026 3 min read

Triglycerides are a type of fat found in your blood. They are an important source of energy, but having high levels can increase your risk of heart disease. Understanding what your triglyceride levels mean can help you maintain your health and make informed decisions about your lifestyle and treatment options.

What are triglycerides?

Triglycerides are a type of lipid, which is a fat or fat-like substance in your body. They are formed when you consume more calories than your body needs, and these extra calories are stored in fat cells to be used later for energy. Triglycerides travel through your bloodstream, and their levels can be measured with a blood test.

Why are triglyceride levels important?

Having a high level of triglycerides in your blood can increase your risk of developing cardiovascular diseases such as heart attack and stroke. High triglyceride levels can also be associated with other conditions like obesity, metabolic syndrome, and type 2 diabetes. Monitoring your triglyceride levels can be an important part of assessing your overall heart health.

What is the normal range for triglycerides?

Triglyceride levels are measured in milligrams per deciliter (mg/dL). According to widely accepted clinical guidelines, the normal range for triglycerides is typically:

  • Normal: Less than 150 mg/dL
  • Borderline High: 150-199 mg/dL
  • High: 200-499 mg/dL
  • Very High: 500 mg/dL and above

These ranges can help you and your healthcare provider understand your risk level and make decisions about your diet, exercise, and medication if needed.

Factors affecting triglyceride levels

Several factors can influence your triglyceride levels, including:

  • Diet: Consuming high amounts of sugar, alcohol, and saturated fats can raise triglyceride levels.
  • Weight: Being overweight or obese can contribute to higher triglyceride levels.
  • Physical activity: Regular exercise can help lower triglyceride levels.
  • Genetics: Your family history can play a role in your triglyceride levels.
  • Medical conditions: Conditions like diabetes, kidney disease, and hypothyroidism can affect triglyceride levels.

How to read your triglyceride test results

When you get your triglyceride levels checked, your healthcare provider will compare your results to the normal range. If your levels are higher than normal, your provider may recommend lifestyle changes such as improving your diet, increasing physical activity, or losing weight. In some cases, medication may be necessary to help lower your triglyceride levels.

Frequently asked questions

What can I do to lower my triglyceride levels? Eating a healthy diet, exercising regularly, losing weight if needed, and reducing alcohol intake can help lower your triglyceride levels.

Can high triglyceride levels be genetic? Yes, genetics can play a role in your triglyceride levels. If high triglycerides run in your family, you may be at a higher risk of having elevated levels.

How often should I have my triglyceride levels checked? It's a good idea to have your triglyceride levels checked as part of a routine lipid panel. Your healthcare provider can recommend how often you should be tested based on your individual risk factors.

When to see a doctor

If your triglyceride levels are elevated or you have risk factors for heart disease, it's important to discuss your results with your healthcare provider. They can help determine the best course of action and whether lifestyle changes or medication are necessary. If you experience symptoms like chest pain or shortness of breath, seek medical attention immediately.
