Fatty liver living in children

Overview

Fatty liver disease happens when too much fat builds up inside liver cells. In children, this is often linked to being overweight or having unhealthy eating habits. It can cause the liver to become inflamed, but with the right changes, it can be reversed or managed.

Yes, non-alcoholic fatty liver disease (NAFLD) is now one of the most common liver conditions in children, especially where rates of childhood obesity are high.

It mostly affects children who are overweight or obese, but it can also run in families or be linked to conditions like type 2 diabetes.

Symptoms

Common symptoms

• Often there are no noticeable symptoms.
• Some children may feel tired or have a dull ache in the upper right belly area.

Symptoms in children

• Many children have no symptoms at all.
• If symptoms do occur, they may include tiredness, belly pain on the right side, or a general feeling of being unwell.

Symptoms in older adults

• Adults may have similar symptoms, but fatty liver is often discovered during tests for other conditions.

Causes

Main causes

• The most common cause is an unhealthy diet high in sugar and processed foods, together with not enough physical activity.
• In some rarer cases, it can be caused by certain medications, genetic conditions, or rapid weight loss.

Risk factors

• Being overweight or obese
• Having type 2 diabetes or prediabetes
• Having high cholesterol or high triglycerides
• A family history of fatty liver disease

When to see a doctor

See a doctor urgently if:

• If your child has jaundice (yellow skin or eyes)
• If your child has severe belly pain that doesn't stop
• If your child seems confused or very sleepy

Book a routine appointment if:

• If you notice ongoing tiredness or belly discomfort
• If your child is overweight and you're concerned about their liver health
• If your child has a condition like diabetes or high cholesterol

Diagnosis

Your doctor will ask about your child's symptoms, diet, activity level, and family history. They may feel your child's belly to check if the liver is enlarged.

Tests that may be done

• Blood tests to check liver enzymes and rule out other causes
• An ultrasound of the abdomen, which uses sound waves to see fat in the liver
• Sometimes a special scan called FibroScan to measure liver stiffness

What to expect at your appointment

Diagnosis is usually straightforward and does not hurt. The doctor will explain the results and work with you to create a plan to improve your child's health.

Treatment

The main treatment for fatty liver in children is lifestyle change: eating healthier and being more active. There are no specific medicines approved for fatty liver in children, but managing any related health problems like diabetes or high cholesterol is important.

Self-care at home

• Encourage a balanced diet with plenty of vegetables, fruits, whole grains, and lean proteins.
• Limit sugary drinks, sweets, and processed snacks.
• Aim for at least 60 minutes of physical activity each day.
• Help your child maintain a healthy weight with gradual, steady changes.

Medical treatments

If your child has an underlying condition like type 2 diabetes or high cholesterol, the doctor may prescribe medicines to manage those conditions. For fatty liver itself, the focus remains on diet and exercise.

When is surgery considered?

Surgery is rarely needed for fatty liver in children. In very severe cases with advanced liver damage, a liver transplant might be considered, but this is extremely rare and only happens when all other options have failed.

Living with this condition

Living with fatty liver means making healthy habits a family affair. Small changes, like swapping sugary drinks for water and going for walks together, can make a big difference.

Lifestyle tips

• Get the whole family involved in healthy eating and exercise.
• Set limits on screen time and encourage outdoor play.
• Make mealtimes enjoyable and focus on balanced plates.

Diet and exercise

Focus on a diet rich in vegetables, lean proteins, and whole grains. Avoid junk food and sugary drinks. Aim for at least an hour of active play each day. Even a 20-minute walk after dinner can help.

Mental health and emotional wellbeing

Having a chronic condition can be stressful for a child. They may feel different from friends or worry about their health. Be supportive, listen to their concerns, and watch for signs of anxiety or low mood.

Prevention

Yes, fatty liver can often be prevented with a healthy diet and regular physical activity from an early age. Maintaining a healthy weight is the best protection.

Vaccines

The usual childhood vaccines are important for overall health, but no specific vaccine prevents fatty liver disease.

Screening programmes

Routine screening for fatty liver is not recommended for all children. However, doctors may check liver health in children who are overweight or have other risk factors like diabetes.

Complications

If left untreated

• Inflammation of the liver (called steatohepatitis)
• Scarring of the liver (fibrosis)
• Severe scarring that affects liver function (cirrhosis)

Long-term outlook

The good news is that for most children, fatty liver is reversible with healthy changes. The liver can heal itself if the fat is reduced. With the right support and habits, children can grow up with a healthy liver and lower risk of future problems.
