Here’s what a few of them had to say
Nonalcoholic fatty liver disease occurs when excess fat builds up in the liver in people who consume little to no alcohol. In recent years, NAFLD has become one of the most diagnosed liver conditions in Australia, affecting nearly one in three adults, and it’s increasingly being seen in younger people as well.
Although often slow to develop, NAFLD can silently damage the liver over time. The early stages may go unnoticed, but when identified and addressed early, outcomes are generally positive. With lifestyle changes, regular monitoring, and professional guidance, many people can reduce liver fat, slow progression, and feel better day to day. This page walks through the key aspects of nonalcoholic fatty liver disease treatment, from diagnosis to long-term management.
What is nonalcoholic fatty liver disease (NAFLD)?
- Fat accumulation without alcohol use – Nonalcoholic fatty liver disease occurs when fat builds up in the liver of people who drink little or no alcohol. The excess fat disrupts normal liver function and can trigger inflammation or scarring if left untreated.
- Linked to metabolic health – People with obesity, insulin resistance, or high cholesterol are particularly at risk. These underlying factors are also known to contribute to heart disease and type 2 diabetes, making NAFLD part of a wider health picture.
- Can be silent for years – NAFLD causes no noticeable symptoms in the early stages. It may only be discovered during a routine blood test or scan for another medical issue. That’s why early screening is often recommended for people with risk factors.
- Progression is possible – Left unmanaged, simple fatty liver can evolve into the more serious nonalcoholic steatohepatitis (NASH), where the liver becomes inflamed. This may then lead to fibrosis (scarring), cirrhosis, and in rare cases, liver failure.
How is NAFLD diagnosed?
- Routine blood tests – Blood tests are often the first step. Elevated liver enzymes, such as ALT, can indicate liver irritation. While not always specific to NAFLD, abnormal results usually prompt further investigation.
- Imaging scans – Ultrasound is commonly used to detect liver fat. More advanced imaging, such as MRI or CT scans, may be used to assess the degree of fat accumulation in the liver and rule out other causes.
- FibroScan or elastography – FibroScan is a quick, non-invasive test that measures liver stiffness and fat content. It helps doctors determine whether scarring has developed, and it’s often used in ongoing monitoring.
- Liver biopsy in select cases – When there’s a concern about advanced liver damage, a biopsy may be needed. This involves removing a sample of liver tissue for examination. It remains the most definitive way to diagnose NASH.

What does nonalcoholic fatty liver disease treatment include?
- Weight loss through lifestyle changes – Sustainable weight loss has been shown to reverse liver fat and reduce inflammation. Even losing 10 % of body weight can significantly improve liver health, especially in early-stage NAFLD.
- Healthy eating habits – Adopting a liver-friendly diet that prioritises whole foods, vegetables, and unsaturated fats can support metabolic balance. Reducing portion sizes and avoiding processed foods also play a key role.
- Regular physical activity – Exercise improves insulin sensitivity, reduces liver fat, and lowers inflammation. A consistent routine of moderate aerobic activity is ideal, especially when combined with resistance training.
- Managing underlying conditions – For people with type 2 diabetes, high blood pressure, or high cholesterol, effective control of these conditions is vital. Better metabolic health often leads to better liver outcomes as well.
Are medications available for NAFLD?
- No approved cure yet – There is no single medication in Australia specifically approved to cure NAFLD. Most treatments focus on addressing the causes and consequences of the disease rather than the liver fat directly.
- Some diabetes medications may help – Certain medications prescribed for diabetes, like pioglitazone, have shown benefits in some patients with NASH. These drugs are not suitable for everyone but may be considered in individualised care.
- Vitamin E for selected patients – Vitamin E has antioxidant properties that may reduce liver inflammation in people without diabetes and with biopsy-proven NASH. However, long-term use requires caution and regular monitoring.
- Ongoing research – Clinical trials continue to investigate promising medications aimed at halting or reversing liver damage. People interested in taking part in research may be eligible for trials through hospitals.

How is long-term NAFLD managed?
- Regular liver monitoring – Long-term care typically includes blood tests and imaging to monitor liver function and ensure the disease is not progressing. Early detection of worsening liver health allows for quicker adjustments to treatment.
- Support from your healthcare team – Managing NAFLD often involves several professionals working together. GPs, endocrinologists, hepatologists, and accredited practising dietitians may work together to create a comprehensive, personalised treatment plan.
- Patient education – Being informed about your condition gives you the tools to make lasting health changes. Many clinics provide resources, workshops, or referrals to help patients learn about diet, exercise, and condition-specific care.
- Adjusting treatment as needed – As your liver responds to changes or new health conditions arise, your doctor may revise your current treatment plan. What works in the early stages of the condition may need to be updated over time to stay effective.
Not sure where to start?
If you’ve recently been diagnosed with NAFLD or suspect you may be at risk, it’s normal to feel unsure about what comes next. But you don’t have to manage it alone. The earlier you begin making changes and seeking medical guidance, the more likely you are to prevent future complications.
Nonalcoholic fatty liver disease treatment doesn’t need to be extreme. Small, sustainable changes can result in significant improvements in liver function and overall well-being. With support from a healthcare team, you can take practical steps toward reversing liver fat and protecting your long-term health.
Nonalcoholic fatty liver disease treatment works best when approached with consistency, information, and the right support system. If you’re unsure about your symptoms or want to discuss your options, speaking to an expert in hepatology is a good first step. The path to a healthier liver can begin today.

FAQs
Can losing weight too quickly worsen NAFLD?
Rapid weight loss through extreme dieting can sometimes stress the liver. It’s best to aim for gradual, steady weight loss under medical supervision.
Are plant-based diets recommended for NAFLD?
Yes, plant-based eating that includes a wide variety of whole foods can support liver health. However, it should be balanced to ensure all nutrients are covered.
How often should I have my liver checked if I have NAFLD?
This depends on your overall risk and the stage of the disease. Your doctor may recommend blood tests and imaging every 6 to 12 months for routine monitoring.
Can NAFLD affect people who are not overweight?
Yes. While most people with NAFLD are overweight, it can also occur in those with a normal weight, particularly if there is insulin resistance or a family history.
