Fatty liver living in pregnancy

Overview

Fatty liver means there is extra fat stored in your liver cells. During pregnancy, this can be a condition you already have (non-alcoholic fatty liver disease) or a rare but serious problem that starts suddenly (acute fatty liver of pregnancy). Either way, it needs careful medical care.

Non-alcoholic fatty liver disease is common in pregnancy, especially in women who are overweight or have diabetes. Acute fatty liver of pregnancy is rare, affecting about 1 in 10,000 to 20,000 pregnancies.

It affects pregnant women, most often those who are overweight, have type 2 diabetes or high blood pressure, or who had fatty liver before pregnancy. Acute fatty liver usually occurs in the third trimester or just after delivery.

Symptoms

Common symptoms

• No symptoms at all in many cases
• Feeling tired or generally unwell
• Mild discomfort in the upper right area of the belly

Causes

Main causes

• Pre-existing non-alcoholic fatty liver disease (often linked to being overweight or having insulin resistance)
• Pregnancy itself can sometimes trigger the buildup of fat in the liver in women who are susceptible
• Acute fatty liver of pregnancy is caused by a problem with how the liver processes fatty acids, and it often runs in families

Risk factors

• Being overweight or obese
• Having type 2 diabetes or gestational diabetes
• Having high blood pressure or preeclampsia
• Rapid weight gain during pregnancy
• Being pregnant with twins or more
• Having had acute fatty liver in a previous pregnancy (for the rare form)

When to see a doctor

See a doctor urgently if:

• Any of the emergency symptoms listed above — seek immediate care
• Signs of jaundice or sudden severe belly pain

Book a routine appointment if:

• If you have known fatty liver disease and are pregnant or planning a pregnancy, talk to your doctor early
• Attend all routine prenatal visits so your blood tests and blood pressure can be checked

Diagnosis

Fatty liver is often found during routine prenatal blood tests that show higher than normal liver enzymes. Your doctor may also order an ultrasound scan of your liver to look for fat buildup.

Tests that may be done

• Blood tests to check liver function (ALT, AST, and other enzymes)
• Ultrasound scan of the abdomen to see the liver
• Sometimes a blood test to check for acute fatty liver of pregnancy (including clotting factors and other markers) if symptoms suggest it

What to expect at your appointment

Your doctor will explain the results and may refer you to a specialist, such as a hepatologist (liver doctor) or a maternal-fetal medicine specialist. You will be monitored throughout your pregnancy with regular blood tests and ultrasounds to keep an eye on your liver and your baby.

Treatment

Treatment focuses on managing the condition safely during pregnancy, mainly through lifestyle changes and close medical supervision. If acute fatty liver occurs, the baby may need to be delivered early, and the mother will receive supportive care in the hospital.

Self-care at home

• Follow a healthy pregnancy diet: eat plenty of vegetables, fruits, whole grains, and lean protein. Avoid sugary drinks, sweets, and fried or fatty foods.
• Stay active with gentle exercise like walking, swimming, or prenatal yoga – always check with your doctor first.
• Avoid alcohol completely – it can make fatty liver worse.

Medical treatments

Your doctor will manage any other health problems you have, such as high blood pressure or diabetes, with medications that are safe in pregnancy. There are no specific medicines approved to treat fatty liver itself, but controlling your weight and blood sugar is key. If acute fatty liver of pregnancy develops, care involves close monitoring in hospital, sometimes including early delivery of the baby and treatments to support your liver function.

When is surgery considered?

Surgery is not usually needed for fatty liver in pregnancy. In very rare cases of severe liver failure, a liver transplant might be considered after the baby is delivered, but this is extremely uncommon.

Living with this condition

Living with fatty liver during pregnancy means staying in close touch with your healthcare team. Attend all appointments, eat well, and rest when you need to. Let your doctor know if you have any new or worsening symptoms.

Lifestyle tips

• Eat small, frequent meals to help control blood sugar and avoid overloading your liver.
• Stay hydrated with water instead of sugary or caffeinated drinks.
• Aim for gentle physical activity most days, as approved by your doctor.

Diet and exercise

A balanced diet low in sugar, refined carbs, and unhealthy fats is important. Focus on vegetables, legumes, lean meats, fish, and healthy fats like nuts and olive oil. Exercise such as walking, swimming, or stationary cycling can help improve your liver health and overall well-being during pregnancy.

Mental health and emotional wellbeing

Having a liver condition during pregnancy can feel worrying. It is normal to feel anxious or stressed. Talk to your doctor or a mental health professional if you are feeling overwhelmed. You can also reach out to trusted friends or family for support.

Prevention

You can reduce your risk of developing fatty liver before or during pregnancy by maintaining a healthy weight, eating a balanced diet, and staying active. If you already have fatty liver, careful management during pregnancy can prevent it from worsening.

Screening programmes

Prenatal care includes routine blood tests that can detect liver problems early. If you have risk factors, your doctor may order additional testing. There is no standard screening for fatty liver in all pregnant women, but it is part of overall prenatal monitoring.

Complications

If left untreated

• Worsening of fatty liver disease, leading to inflammation and scar tissue (cirrhosis) over time
• Acute fatty liver of pregnancy can cause liver failure, dangerously high blood pressure (preeclampsia), and harm to the baby, including preterm birth or stillbirth
• Bleeding problems due to the liver not making enough clotting factors

Long-term outlook

With proper medical care, the vast majority of women with fatty liver during pregnancy have a healthy pregnancy and baby. Even if acute fatty liver develops, quick treatment in a hospital gives good chances for recovery. After delivery, the liver often heals, but it is important to continue healthy habits and follow up with your doctor to prevent long-term liver damage.
