Pancreatitis in Pregnancy: Causes and Risk Factors

Pathophysiology and Risk Factors

Pregnancy induces a "physiological hyperlipidemia" with 2-fold increases in circulating triglyceride levels during the third trimester due to enhanced lipolytic activity in adipose tissue, according to the American Heart Association 1
Women with baseline triglyceride levels ≥500 mg/dL may develop severe hypertriglyceridemia during the third trimester, creating substantial pancreatitis risk, as recommended by the American College of Obstetricians and Gynecologists 2
Both insulin resistance and hyperestrogenemia represent causative factors for the development or amplification of hypertriglyceridemia during pregnancy and may present a therapeutic challenge, especially if pancreatitis develops, as stated by the American Diabetes Association 1

The estimated incidence of gallstone-related disease complicating pregnancy is 0.5% to 0.8%, according to the American Association for the Study of Liver Diseases 3
High-risk women, including those with poorly controlled diabetes mellitus, should have triglyceride levels checked once every trimester, as recommended by the American College of Obstetricians and Gynecologists 2
Women with preexisting gallstones, obesity (high prepregnancy BMI), or elevated serum leptin levels are at increased risk, as stated by the American Association for the Study of Liver Diseases 3
Triglyceride levels ≥500 mg/dL significantly increase pancreatitis risk, with risk increasing proportionally at higher levels, according to the American College of Obstetricians and Gynecologists 4

Do not delay intervention until pancreatitis develops, as maternal mortality from gestational hypertriglyceridemic pancreatitis approaches 20%, as warned by the American College of Obstetricians and Gynecologists 2
Do not use low-fat, high-carbohydrate diets without carbohydrate restriction, as excessive carbohydrates are converted to triglycerides, as recommended by the American College of Obstetricians and Gynecologists 2
