Non-Alcoholic Fatty Liver Disease (NAFLD) is increasingly affecting children, especially boys, due to rising obesity and poor lifestyle habits like inactivity and consumption of processed foods. NAFLD can begin as early as age 10 and often shows no symptoms, making it hard to detect. If left untreated, it can progress to non-alcoholic steatohepatitis (NASH), a more severe condition involving liver inflammation and scarring. Diagnosis usually involves liver enzyme blood tests, imaging scans, and sometimes biopsies. While there’s no cure, early-stage NAFLD can be managed through lifestyle changes: healthier eating, regular exercise, weight management, and improved metabolic health. Even modest weight loss can reduce fat buildup in the liver. Long-term success depends on maintaining these changes. Parents play a vital role by modelling healthy behaviour and creating a supportive environment. With consistent effort, children can lead normal lives but lapses in lifestyle can lead to serious complications such as cirrhosis, liver failure, or cancer.
Fatty Liver Disease is a health condition that affects the liver. Fat deposits build up in the liver, causing it to swell and become damaged. If left unchecked, the condition can deteriorate and lead to serious scarring of the liver – This is called cirrhosis. When the liver disease reaches cirrhosis, the liver tissue loses its function and stops filtering impurities out of the blood. This causes a host of other complications, many of which can be fatal. Fatty Liver is often caused by an excessive consumption of alcohol, and high levels of fat in the blood stream.
No, not always. Although that is one of the most common causes, fatty liver can also be caused by other problems – We call this Non-Alcoholic Fatty Liver Disease. Non-Alcoholic Fatty Liver Disease is on the rise in many countries, as the obesity rates are increasing.
Non-Alcoholic Fatty Liver Disease (NAFLD) can even occur in children. Interestingly, the disease is more common in male children than female children. NAFLD affects about 1 in 10 children worldwide. According to the American Liver Foundation, the number of children who get NAFLD has almost doubled in the last 20 years. This could be because childhood obesity rates are also on the rise, globally. Children spend less time playing and eat more processed foods now than they ever have in the past. The lifestyle factors causing this unhealthy trend need to be addressed to treat the condition effectively. NAFLD can affect children as young as 10 years old. If left untreated, NAFLD can lead to serious liver inflammation and scarring, called non-alcoholic steatohepatitis (NASH). Children often don’t experience any symptoms, which makes the condition dangerous and difficult to catch. Often, patients are diagnosed only after the condition progresses to NASH.
NAFLD often doesn’t cause obvious symptoms. Patients may have only mild stomach aches and have a general feeling of fatigue. The symptoms tend to worsen as the amount of fatty deposits and inflammation increases. Once it progresses to NASH, patients may have itchy skin, swelling go the legs, shortness of breath and yellowing of the eyes and skin (jaundice). Some patients may also have an enlarged spleen, abdominal swelling (ascites) and spidery blood vessels beneath the skin.
The exact cause of Non-Alcoholic Fatty Liver Disease is unclear. Experts differ in their theories, and further research is needed to establish a clear trigger. However, from our research, we know some of the risk factors and conditions linked to NAFLD. Patients who have pre-existing conditions like type 2 diabetes, insulin resistance, polycystic ovary syndrome, obstructive sleep apnea, hypothyroidism and hepatitis C have a higher risk of suffering from NAFLD. People who are obese, pre-diabetic, or have insulin resistance also face a higher risk. Family history also needs to be taken into account. Interestingly, though, sometimes people who don’t have any of these risk factors also suffer from NAFLD, but researchers have no idea why.
In children, fatty liver disease often does not exhibit any noteworthy symptoms. Routine health check-ups are important for kids, so the primary care doctor can identify potential illnesses before they progress. Doctors usually diagnose non-alcoholic fatty liver disease in children based on a family medical history, and a panel of blood tests. The blood tests will show if the patient has high levels of liver enzymes, which is an indicator of NAFLD. The doctor may also perform additional tests, including an ultrasound scan, a transient elastography and a needle biopsy. These tests will help identify how much liver damage has occurred, so the doctor can create an appropriate treatment plan. If your child has been diagnosed with Non-Alcoholic Fatty Liver Disease, the doctors will likely repeat these tests periodically to monitor progress.
There is no medication or guaranteed cure for Fatty Liver Disease. In children, the treatment program will focus on slowing down and stopping fat build up in the liver and generally minimizing damage to the liver tissue. This is achieved through lifestyle changes. Patients are advised to modify their diets. Children are advised to switch to diets with less processed foods, trans fats and saturated fats. Whole foods, including grains, fruits, vegetables and lean proteins are recommended. Healthy fats like olive oil and nuts can be included in moderation. The patient will also be advised to exercise, with a focus on building muscle and improving metabolism. This helps counter insulin resistance. The dual-prong approach of diet and exercise can help the child manage their condition, and function normally. Having said that, it is important to remember that Fatty Liver Disease is chronic, and the patient will need to sustain this healthy lifestyle in the long-term. Falling back into an unhealthy lifestyle will reverse the progress they have made. This can be very dangerous as scar tissue can begin to develop, leading to liver damage and further complications like liver cirrhosis, cancer and portal hypertension.
The ideal scenario is always prevention – This applies for any medical condition. However, with NAFLD, we cannot 100% prevent the condition because we are unsure what causes it. We do know, though, that it has a high correlation to obesity and insulin resistance, and we can work against those factors. Having a healthy lifestyle is really the key here – Weight Management, a healthy diet, and regular physical activity help prevent the condition. These are also the strategies used to treat the condition.
Paediatric gastroenterologists recommend maintaining a BMI between 18.5 and 24.9. This is considered a healthy range in general, although you could consult with your doctor to find out what’s ideal for you. In children, even a small amount of weight loss can help reduce fat deposits in the liver, so do not give up. Small changes in weight will make a difference as they grow. It is also recommended to find activities that the child enjoys doing, which also benefit their health. It could be dance, running, playing a sport, or even rock climbing. Ideally, the chosen activity should include components of strength, mobility and aerobic activity. Building muscle is important – Children are able to build muscle more easily than adults, and studies suggest that having good muscle mass improves metabolism and reduces insulin resistance.
In terms of diet, doctor’s advise portion control. Although growing children need fuel, a dietician will be able to advise you about exactly how much food your child needs to eat, for their age, gender, height and activity levels. The kind of food the child eats is also important. Empty calories will just add to the problem. Instead, they need to get their energy from whole foods and have adequate protein intake. It may also be worth exploring whether the child is an emotional eater, and what the underlying causes for that may be. Resolving the emotional conflicts could help the child have a healthier relationship with food.
Parents also play a crucial role in modelling a healthy lifestyle for their child. Try to get the whole family to eat healthy and exercise, so the child feels like a normal part of the household. Making the child feel “othered” could make them feel bad, and ultimately not help them adopt these lifestyle changes in the long run.
Early awareness and healthy lifestyle habits can make a significant difference in preventing and managing fatty liver disease in children. With the right medical guidance, regular monitoring, and family support, many children can successfully control the condition and lead healthy lives.
