cholesterol in pregnancy

Overview

Cholesterol is a waxy, fat-like substance that your body needs to build cells and make hormones. During pregnancy, it is normal for cholesterol levels to rise because your body needs extra cholesterol to support your baby’s growth and development. This increase is usually temporary and goes back to normal after delivery. However, very high cholesterol during pregnancy may increase the risk of complications like preeclampsia (high blood pressure and organ damage) or gestational diabetes. Managing your cholesterol with healthy habits is important for you and your baby.

Yes, it is very common for cholesterol levels to rise during pregnancy. This happens in most pregnancies to some degree and is considered a normal part of the body’s adaptation to support the baby.

High cholesterol in pregnancy can affect any pregnant woman, but it is more common in women who already have high cholesterol before pregnancy, have a family history of high cholesterol, are overweight, have diabetes, or develop preeclampsia or gestational diabetes.

Symptoms

Common symptoms

• High cholesterol itself does not usually cause symptoms. It is often discovered during routine blood tests.

Symptoms in children

• High cholesterol during pregnancy does not directly cause symptoms in the baby, but it may increase the risk of preterm birth or having a larger baby.

Symptoms in older adults

• In older adults, high cholesterol may lead to fatty deposits in blood vessels, but this is not typically a concern during pregnancy itself.

Causes

Main causes

• Normal hormonal changes during pregnancy, especially increased estrogen and other hormones, cause the liver to produce more cholesterol.
• The body needs extra cholesterol to build the placenta and support the baby's brain and organ development.

Risk factors

• Having high cholesterol before pregnancy
• Being overweight or obese
• Having diabetes or gestational diabetes
• Having a family history of high cholesterol or heart disease
• Eating a diet high in saturated fats, trans fats, and sugar
• Not being physically active
• Smoking or using tobacco products

When to see a doctor

See a doctor urgently if:

• If you experience any of the emergency symptoms listed above, call your local emergency number immediately.
• If you have a blood pressure reading of 140/90 mmHg or higher, contact your healthcare provider or midwife that day.

Book a routine appointment if:

• Tell your healthcare provider if you have a personal or family history of high cholesterol or heart disease.
• Attend all your routine prenatal appointments, where your blood pressure and other health checks are done.
• Ask your doctor or midwife about getting a blood test to check your cholesterol levels if you have risk factors.

Diagnosis

High cholesterol during pregnancy is diagnosed with a simple blood test that measures your total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol, and triglycerides. This test is usually done during your first prenatal visit or later if your doctor suspects a problem.

Tests that may be done

• Lipid panel (blood test) that checks cholesterol and triglycerides
• Blood pressure checks at every prenatal visit
• Urine test to check for protein, which can indicate preeclampsia
• Blood sugar test to screen for gestational diabetes

What to expect at your appointment

If your cholesterol levels are high, your healthcare provider will review them along with other health factors like your blood pressure and weight. They may recommend lifestyle changes first. Usually, no treatment is needed unless your levels are very high or you have other conditions. After delivery, your levels will be checked again to make sure they return to normal.

Treatment

Treatment for high cholesterol during pregnancy focuses on safe lifestyle changes because most cholesterol medications are not recommended during pregnancy. The goal is to keep your levels in a healthy range to reduce the risk of complications. Your healthcare provider will individualize your care based on your results and overall health.

Self-care at home

• Eat a heart-healthy diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats like those in nuts, seeds, and avocado.
• Stay physically active with activities approved by your healthcare provider, such as walking, swimming, or prenatal yoga.
• Avoid foods high in saturated and trans fats, like fried foods, pastries, and processed snacks.
• Limit sugary drinks and sweets.
• Do not smoke or use tobacco products.
• Maintain a healthy weight gain during pregnancy as recommended by your provider.

Medical treatments

In rare cases where cholesterol levels are extremely high and lifestyle changes are not enough, your healthcare provider may consider a medication that is safe during pregnancy. These are only used under close supervision. The most common approach is to continue lifestyle changes and monitor after delivery. Never take any cholesterol-lowering medication without your doctor’s advice during pregnancy.

When is surgery considered?

Surgery is not used for high cholesterol in pregnancy.

Living with this condition

Living with high cholesterol during pregnancy means making healthy choices every day. You can manage it by following your prenatal care plan, eating well, staying active, and attending all check-ups. Most women do not feel any different, and the condition rarely causes daily symptoms.

Lifestyle tips

• Eat a balanced diet with plenty of fiber, such as oats, beans, lentils, and fresh vegetables.
• Choose healthy cooking methods like baking, grilling, or steaming instead of frying.
• Take a prenatal vitamin as recommended by your healthcare provider.
• Get regular physical activity, like walking for 30 minutes most days.
• Manage stress with relaxation techniques like deep breathing or meditation.
• Get enough sleep and rest.

Diet and exercise

A heart-healthy diet and regular exercise are key. Focus on eating more plant-based foods, lean proteins (like fish, chicken, and beans), and healthy fats from sources like olive oil and avocados. Avoid processed foods, sugary snacks, and high-fat meats. Exercise such as walking, swimming, or prenatal yoga can help control weight gain and improve cholesterol levels. Always check with your healthcare provider before starting a new exercise routine.

Mental health and emotional wellbeing

Being told you have high cholesterol during pregnancy can cause worry or stress. It is normal to feel concerned, but remember that this condition is usually temporary and manageable. If you feel anxious or overwhelmed, talk to your healthcare provider or a mental health professional. You can also reach out to a support line if you need immediate emotional help.

Prevention

You cannot fully prevent the natural rise in cholesterol during pregnancy, but you can reduce the risk of having very high levels. Maintaining a healthy weight before pregnancy, eating a balanced diet, staying active, and avoiding smoking can help keep your cholesterol in a healthy range.

Screening programmes

Routine prenatal blood tests usually include a lipid panel. If you have risk factors, your provider may check your cholesterol early in pregnancy and again in the third trimester. After delivery, a follow-up blood test is often done to ensure levels return to normal.

Complications

If left untreated

• Very high cholesterol may increase the risk of preeclampsia, a serious condition with high blood pressure that can affect the liver, kidneys, and the baby.
• It may also increase the risk of gestational diabetes.
• In some cases, it can be associated with preterm birth or having a larger baby (macrosomia).
• For the mother, untreated high cholesterol may contribute to long-term heart disease risk after pregnancy.

Long-term outlook

For most women, the rise in cholesterol during pregnancy is normal and temporary. With healthy habits and good prenatal care, the outlook is excellent. Your levels will likely return to normal after delivery. Even if your levels are high, working with your healthcare provider can help you manage them safely. Take heart: your body is doing amazing work to support your baby, and you have the tools to keep both of you healthy.
