High Triglycerides Treatment: How to Lower Your Levels Safely

Your blood test came back with a number you didn't expect, and now "high triglycerides" is sitting in your results. It sounds alarming, but for most people it's very manageable, and the first steps are things you can start on this week. Here's what high triglycerides treatment actually looks like, and how to know when it's urgent.

What counts as high triglycerides?

Triglycerides are a type of fat your body carries in the blood. Doctors group your level into ranges, which tells you how aggressive treatment needs to be. The thresholds used by the NIH and Mayo Clinic come from a fasting blood test.

• 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

Why treatment matters

High triglycerides matter for two reasons. Over time, elevated levels are linked to a higher risk of heart and blood vessel disease, which is why treatment plans often look at your overall cardiovascular risk, not just one number.

The second reason is more immediate. Very high triglycerides, above 500 mg/dL, raise the risk of acute pancreatitis, a painful and serious inflammation of the pancreas. For levels above 1000 mg/dL, the 2026 ACC/AHA dyslipidemia guideline recommends medication plus lifestyle changes specifically to lower that pancreatitis risk. This is also why severe numbers get treated quickly rather than with a wait-and-see approach.

Lifestyle changes: the first-line treatment

For most people, lifestyle change is the foundation of treatment, and it can be remarkably effective. According to the 2026 ACC/AHA guideline, lifestyle change is first-line therapy and can lower triglycerides by more than 70% in highly responsive individuals. Diet does much of the heavy lifting here, especially predominantly plant-based eating patterns like the Mediterranean or DASH diets and cutting back on added and simple sugars.

Mayo Clinic's practical recommendations give you a clear starting list.

• Aim for at least 30 minutes of physical activity on most or all days
• Cut back on refined carbohydrates, sugar, and fructose
• Lose excess weight if your doctor advises it
• Limit alcohol, and avoid it entirely if your triglycerides are severely elevated

Medications for high triglycerides

When lifestyle changes alone aren't enough, or when levels are very high to begin with, doctors add medication. The choice depends on how high your triglycerides are and whether your cholesterol is also elevated or you have diabetes or established heart disease.

Commonly used options include fibrates such as fenofibrate and gemfibrozil, statins (especially when cholesterol is also high or your cardiovascular risk is elevated), niacin, and prescription omega-3 fatty acids. For severe hypertriglyceridemia, the 2026 ACC/AHA guideline points to a fibrate as the first-line drug. One prescription omega-3 medication, icosapent ethyl, has strong evidence behind it: in the REDUCE-IT trial published in 2019, 4 grams a day reduced major cardiovascular events by 25% in statin-treated patients with triglycerides of 135 to 499 mg/dL, with the primary event occurring in 17.2% of that group versus 22.0% on placebo.

Which medication is right for you, and at what dose, is a decision for your clinician. This article is general education, not a prescription.

When to see a doctor

Any high triglyceride result is worth discussing with a clinician so you can confirm it with a repeat fasting test and look for underlying causes like uncontrolled diabetes, alcohol use, certain medications, or genetics. But some situations need prompt attention.

Seek urgent or emergency care if you have severe, persistent upper-abdominal pain, especially with nausea or vomiting, which can be a sign of pancreatitis. If your levels are in the very high range, don't wait to start treatment, as those numbers carry real short-term risk.
