Treatment of Hypertriglyceridemia

Classification and Diagnosis

Hypertriglyceridemia is classified by severity: Normal (<150 mg/dL), Mild (150-199 mg/dL), Moderate (200-999 mg/dL), Severe (1,000-1,999 mg/dL), and Very Severe (≥2,000 mg/dL) 2, 3
Mild to moderate hypertriglyceridemia is associated with increased cardiovascular risk, while severe and very severe levels increase the risk of pancreatitis 4, 3
Before initiating treatment, evaluate for secondary causes including excessive alcohol intake, uncontrolled diabetes, hypothyroidism, renal disease, liver disease, and certain medications (thiazides, beta-blockers, estrogen, corticosteroids) 2, 3

Target a 5-10% weight loss, which can reduce triglycerides by up to 20% 1
Restrict added sugars to <6% of total daily calories and limit total fat to 30-35% of total daily calories for mild to moderate hypertriglyceridemia 1, 3
For severe hypertriglyceridemia (500-999 mg/dL), further restrict added sugars to <5% and total fat to 20-25% of total daily calories 1
For very severe hypertriglyceridemia (≥1,000 mg/dL), eliminate added sugars and restrict total fat to 10-15% of daily calories 1
Engage in at least 150 minutes/week of moderate-intensity or 75 minutes/week of vigorous aerobic activity 1, 3
Limit or completely avoid alcohol consumption, especially in patients with severe hypertriglyceridemia 1, 2, 3

Fibrates are the first-line drug therapy to reduce the risk of pancreatitis in patients with severe to very severe hypertriglyceridemia 2, 4, 3
Consider statins if there is elevated LDL-C or increased cardiovascular risk, which can provide a 10-15% reduction in triglycerides 2, 3
Prescription omega-3 fatty acids (2-4g/day) can be considered for patients with persistent hypertriglyceridemia despite lifestyle modifications 3

Optimize glycemic control in patients with diabetes, as it can significantly improve triglyceride levels 3
For patients with triglycerides ≥500 mg/dL, prioritize aggressive triglyceride lowering to reduce the risk of pancreatitis before focusing on LDL-C goals 2, 3
Monitor for potential drug interactions, particularly when combining lipid-lowering medications 3

Reassess fasting lipid panel in 6-12 weeks after implementing lifestyle modifications 3
