Cholesterol naturally rises 30 to 50% during a healthy pregnancy, so the first thing to know is that higher numbers on a lipid panel don’t automatically signal a problem. Your body increases cholesterol production to support your baby’s cell growth, hormone production, and brain development. That said, triglycerides that climb beyond the expected range (they typically double) can raise the risk of complications like preeclampsia, and there are safe, practical steps you can take to keep your lipid levels in a healthy zone.
Why Cholesterol Rises During Pregnancy
In early pregnancy, total cholesterol and LDL actually dip slightly before climbing steadily from the second trimester through delivery. By the third trimester, total cholesterol and LDL are typically 30 to 50% above your pre-pregnancy baseline. HDL, the protective form, rises 20 to 40% early on and levels off around weeks 20 to 24. Triglycerides see the most dramatic jump: 50 to 100% above baseline.
This is normal physiology, not a disease state. Your placenta and your baby’s developing tissues need cholesterol as a raw material. The concern starts when levels rise well beyond these expected ranges, particularly triglycerides. Elevated first-trimester triglycerides are independently linked to gestational hypertension and preeclampsia, and very high triglycerides carry a risk of pancreatitis. Interestingly, research on women with familial hypercholesterolemia (an inherited condition causing very high LDL) has not found a clear link between maternal LDL levels alone and complications like preeclampsia or preterm delivery. Triglycerides appear to be the bigger driver of risk.
A large study of nearly 10,000 women without cardiovascular conditions found that gestational diabetes and preeclampsia occurred in 7.2% of women with low triglycerides but jumped to 19.8% in women with the highest triglyceride levels. That gap makes managing triglycerides during pregnancy especially worthwhile.
Focus on Fiber-Rich Foods
Soluble fiber is one of the most effective dietary tools for pulling cholesterol out of your digestive tract before it enters your bloodstream. It binds to bile acids (which are made from cholesterol) and carries them out of your body, forcing your liver to use more circulating cholesterol to make new ones. The recommended fiber intake during pregnancy is at least 28 grams per day, yet fewer than 30% of pregnant women hit that target in studies tracking dietary habits.
The easiest sources to work into daily meals are apples (about 2.2 grams of fiber per 100 grams, with roughly a third of that being soluble pectin), bananas, oats, and legumes like lentils and chickpeas. Vegetables including broccoli, carrots, avocado, and peas all contribute meaningful fiber. Legumes and nuts tend to be underconsumed during pregnancy, so adding a handful of almonds to a snack or tossing white beans into a soup is a simple upgrade. Whole-grain bread, brown rice, and pasta round out a high-fiber eating pattern, though the soluble fiber in fruits, oats, and legumes has the strongest cholesterol-lowering effect.
Omega-3 Fats for Triglycerides
If triglycerides are your main concern, omega-3 fatty acids can help. A study of pregnant women taking supplements containing EPA and DHA found a significant reduction in triglyceride levels throughout pregnancy. The effect was consistent even after adjusting for age, BMI, and other variables. However, the same study found no meaningful change in total cholesterol, LDL, or HDL from omega-3 supplementation, so this approach targets triglycerides specifically.
You can get omega-3s from fatty fish like salmon, sardines, and mackerel (aim for two servings per week of low-mercury varieties) or from a prenatal supplement that contains DHA and EPA. Many prenatal vitamins already include DHA, but the amount varies. If your provider flags high triglycerides, a dedicated omega-3 supplement with higher EPA content may be more effective than what a standard prenatal vitamin provides.
Move Your Body Regularly
The American College of Obstetricians and Gynecologists recommends at least 150 minutes of moderate-intensity aerobic activity per week during pregnancy. That’s 30 minutes on five days, though you can break it into 10-minute blocks throughout the day and get the same benefit. Moderate intensity means you’re breathing harder and sweating but can still hold a conversation. Walking, swimming, stationary cycling, and prenatal yoga all count.
If you weren’t exercising before pregnancy, start with just five minutes a day and add five minutes each week until you reach 30-minute sessions. Regular movement improves how your body processes fats and sugars, helps control triglyceride levels, and supports healthy weight gain. It also reduces the risk of gestational diabetes, which shares overlapping risk factors with high triglycerides.
What to Avoid or Use With Caution
Plant sterol and stanol products (fortified margarines, yogurt drinks) are a common cholesterol-lowering strategy outside of pregnancy, but they are not recommended for pregnant or breastfeeding women unless specifically advised by a doctor. Because cholesterol is essential for fetal development, blocking its absorption with these products could interfere with the supply your baby needs.
Statins, the most widely prescribed cholesterol drugs, were historically contraindicated across the board during pregnancy. In 2021, the FDA removed that blanket prohibition, recognizing that a small group of very high-risk patients (such as those with homozygous familial hypercholesterolemia or a history of heart attack or stroke) might benefit enough to justify use. For most pregnant women, the guidance remains the same: stop statins once you learn you’re pregnant. The change simply allows doctors and patients in rare, high-risk situations to weigh the decision individually rather than facing an automatic ban.
Bile acid sequestrants are the class of cholesterol-lowering medication with the longest safety track record in pregnancy. These drugs work entirely inside the gut, binding bile acids so they’re excreted rather than recycled. Because they aren’t absorbed into the bloodstream, they don’t cross the placenta. Animal studies on colesevelam, one drug in this class, showed no effect on litter size, fetal viability, birth weight, or development. For women who need medication-level cholesterol reduction during pregnancy, bile acid sequestrants are the option most providers will consider first.
Simple Dietary Swaps That Add Up
Beyond fiber and omega-3s, a few targeted shifts in your eating pattern can meaningfully influence your lipid levels. Replace saturated fats (butter, full-fat cheese, fatty cuts of red meat) with unsaturated fats from olive oil, avocado, and nuts. This swap lowers LDL without restricting overall fat intake, which your body still needs during pregnancy. Reducing refined carbohydrates and added sugars is particularly effective for triglycerides, since your liver converts excess sugar into triglyceride particles. Choosing whole fruit over juice, whole grains over white bread, and water over sweetened drinks are small changes with a direct impact on triglyceride production.
Eating smaller, more frequent meals can also help. Large carbohydrate-heavy meals cause bigger spikes in blood sugar and insulin, which in turn drives triglyceride production. Spreading your intake across four to six smaller meals keeps those spikes more modest.
After Delivery: What to Expect
Triglyceride levels drop back to baseline within days of delivery. Total cholesterol, LDL, and HDL take about a month to normalize. The National Lipid Association recommends a fasting lipid panel around six weeks postpartum, which gives you an accurate read on your true baseline. If your cholesterol was high before pregnancy or you had complications like preeclampsia, that postpartum check is especially important because it establishes whether you need ongoing management outside the context of pregnancy.
