Triglycerides: What Your Result Means

What is Triglycerides?

Triglycerides transport dietary and hepatic fat through blood in chylomicrons/VLDL particles. Non-fasting samples run naturally higher post-meal — modern guidelines accept non-fasting screening with fasting confirmation for elevations. Levels swing more week-to-week than any other lipid.

Typical reference interval: <150 normal · 150–199 borderline · 200–499 high · ≥500 very high (pancreatitis risk zone).. Laboratories differ — the interval printed on YOUR report always governs.

If your Triglycerides is high

Common reasons Triglycerides runs above the reference interval:

• Refined carbohydrates and sugars — fructose especially drives hepatic TG synthesis — soda drinkers know
• Alcohol — potent and dose-dependent
• Diabetes/prediabetes — insulin resistance unleashes VLDL production
• Obesity and sedentarity —
• Genetic hypertriglyceridemia — familial combined/chylomicronemia syndromes
• Medications — steroids, estrogens, tamoxifen, beta-blockers, atypical antipsychotics, protease inhibitors
• Hypothyroidism and CKD — clearance slows

If your Triglycerides is low

Common reasons Triglycerides runs below the reference interval:

• Generally favorable — very low TG accompanies low cardiovascular risk
• Malabsorption/malnutrition —
• Hyperthyroidism — accelerated clearance

Symptoms worth knowing

High TG itself: silent. Extreme hypertriglyceridemia (usually >1000-2000): eruptive xanthomas, lipemia retinalis, and acute pancreatitis — severe abdominal pain radiating to back requiring emergency care. The Friedewald-calculated LDL becomes invalid above 400.

What usually happens next

1. Above 150: recheck FASTING after 2 weeks of alcohol abstinence and carb discipline — often halves
2. Above 500: therapy urgency escalates for pancreatitis prevention
3. Omega-3 doses, fibrates address TG specifically; statins handle overall risk
4. Screen thyroid and glucose alongside
