What is the management for severely elevated triglycerides?

Management of Triglycerides 789 mg/dL

Initiate fenofibrate 54-160 mg daily immediately to prevent acute pancreatitis, combined with aggressive dietary fat restriction to 20-25% of total calories, complete elimination of added sugars and alcohol, and urgent evaluation for uncontrolled diabetes or other secondary causes. 1, 2, 3

Immediate Risk Context

A triglyceride level of 789 mg/dL places you in the severe hypertriglyceridemia category (500-999 mg/dL), which carries significant risk for acute pancreatitis with a 14% incidence at this level. 1, 2 The risk escalates dramatically as levels approach 1,000 mg/dL, making immediate intervention essential rather than optional. 1

Step 1: Urgent Pharmacologic Intervention

Fenofibrate must be started immediately—do not delay while attempting lifestyle modifications alone. 1, 2, 3

• Start fenofibrate 54-160 mg once daily with meals to optimize bioavailability. 3
• Fenofibrate reduces triglycerides by 30-50%, making it the most effective first-line agent for preventing pancreatitis at this level. 1, 2, 3
• Critical: Statins alone are insufficient when triglycerides are ≥500 mg/dL, as they provide only 10-30% triglyceride reduction and do not adequately address pancreatitis risk. 1
• Adjust fenofibrate dose based on renal function—start at 54 mg daily if mild-to-moderate renal impairment exists, and avoid entirely in severe renal impairment. 3

Step 2: Identify and Aggressively Treat Secondary Causes

Before attributing this to primary dyslipidemia, rule out reversible causes that may be the primary driver:

• Check HbA1c immediately—uncontrolled diabetes is often the primary cause of severe hypertriglyceridemia, and optimizing glucose control can dramatically reduce triglycerides independent of lipid medications. 1, 2, 3
• Check TSH to rule out hypothyroidism. 1, 3
• Mandate complete alcohol abstinence—even 1 ounce daily increases triglycerides by 5-10%, and alcohol can precipitate hypertriglyceridemic pancreatitis at this level. 1, 2
• Review medications: thiazide diuretics, beta-blockers, estrogen therapy, corticosteroids, antiretrovirals, and antipsychotics all raise triglycerides and should be discontinued or substituted if possible. 1, 3

Step 3: Aggressive Dietary Interventions (Non-Negotiable)

These dietary changes are mandatory, not optional suggestions:

• Restrict total dietary fat to 20-25% of total daily calories for severe hypertriglyceridemia in the 500-999 mg/dL range. 1, 2
• Completely eliminate all added sugars—sugar intake directly increases hepatic triglyceride production. 1, 2
• Complete abstinence from all alcohol—this is mandatory to prevent hypertriglyceridemic pancreatitis. 1, 2
• Restrict saturated fats to <7% of total calories, replacing with polyunsaturated or monounsaturated fats. 1
• Increase soluble fiber to >10g/day. 1
• Target 5-10% body weight reduction if overweight, which produces a 20% decrease in triglycerides. 1, 2
• Engage in at least 150 minutes per week of moderate-intensity aerobic activity. 1, 2

Step 4: Monitoring Strategy

• Recheck fasting lipid panel in 4-8 weeks after initiating fenofibrate and lifestyle modifications. 1, 2, 3
• Monitor liver function tests (ALT, AST) and creatine kinase at baseline and during treatment to detect hepatotoxicity or myopathy. 1, 2
• Treatment goal: reduce triglycerides to <500 mg/dL urgently to eliminate pancreatitis risk, then target <200 mg/dL (ideally <150 mg/dL) for cardiovascular risk reduction. 1, 2

Step 5: Consider Add-On Therapy if Needed

If triglycerides remain >200 mg/dL after 4-8 weeks of fenofibrate plus optimized lifestyle:

• Add prescription omega-3 fatty acids (icosapent ethyl or omega-3 acid ethyl esters) 2-4g daily as adjunctive therapy. 1, 2
• Do not use over-the-counter fish oil as a substitute—prescription formulations are required for consistent dosing and proven efficacy. 2

Step 6: Address LDL-C Once Triglycerides Are Controlled

Once triglycerides fall below 500 mg/dL with fenofibrate therapy:

• Reassess LDL-C and cardiovascular risk to determine if statin therapy is needed. 1, 2
• If combining fenofibrate with a statin, use lower statin doses (atorvastatin 10-20 mg maximum) to minimize myopathy risk, particularly if age >65 years or renal disease exists. 1
• Use fenofibrate, not gemfibrozil, when combining with statins—gemfibrozil has significantly higher myopathy risk. 1

Critical Pitfalls to Avoid

• Do not delay fenofibrate initiation while attempting lifestyle modifications alone—pharmacologic therapy is mandatory at this triglyceride level. 1, 2
• Do not start with statin monotherapy when triglycerides are ≥500 mg/dL—fibrates must be first-line to prevent pancreatitis. 1
• Do not ignore glycemic control in diabetic patients—poor glucose control is often more important than lipid medications. 1, 2
• Do not use gemfibrozil if statins will be needed later—fenofibrate has a better safety profile for combination therapy. 1
• Monitor for muscle symptoms and obtain CPK levels if combining fibrates with statins, especially in elderly patients or those with renal disease. 1
