Reference Values for VLDL Cholesterol in Pregnancy

Perinatology.com › Reference › Serum Values › VLDL Cholesterol

VLDL Cholesterol (serum / plasma)

VLDL concentrations rise during pregnancy as part of normal maternal lipid adaptation, driven by estrogen-mediated hepatic production and increased triglyceride transport for fetal growth.

Units Nonpregnant Adult 1st Trimester 2nd Trimester 3rd Trimester
mg/dL 6 – 40 10 – 18 13 – 23 21 – 36
mmol/L 0.16 – 1.04 0.26 – 0.47 0.34 – 0.60 0.54 – 0.93

Pregnancy physiology

VLDL particles transport triglycerides from the liver to maternal and placental tissues.

  • Estrogen increases hepatic VLDL production
  • Mild pregnancy-related insulin resistance increases triglyceride mobilization
  • Placental steroidogenesis raises lipid demand
VLDL levels may rise 2–3× baseline by the third trimester.

Causes of elevated VLDL
  • Normal physiologic rise in pregnancy
  • Hypertriglyceridemia
  • Preeclampsia or endothelial dysfunction
  • Gestational diabetes
  • Obesity / metabolic syndrome
  • Familial combined hyperlipidemia
  • Hypothyroidism
  • Nephrotic syndrome
  • High-carbohydrate or high-fructose diet
  • Medications: estrogens, corticosteroids, β-blockers, atypical antipsychotics
Causes of low VLDL
  • Malnutrition or inadequate caloric intake
  • Malabsorption (celiac disease, pancreatic insufficiency)
  • Advanced liver disease / reduced hepatic synthesis
  • Hyperthyroidism
  • Genetic hypolipidemias (abetalipoproteinemia, APOC2 deficiency)
  • Critical illness

Low VLDL is uncommon; when present, it usually reflects impaired hepatic triglyceride production.
