Non-alcoholic fatty Liver Disease (NAFLD) is becoming a significant health concern in India, affecting a growing portion of the population due to the rise in obesity, type 2 diabetes, and sedentary lifestyles. According to a study published in the Journal of Clinical and Experimental Hepatology, approximately 9-32% of India’s general population is estimated to have NAFLD, making it one of the most prevalent liver diseases in the country. NAFLD is associated with metabolic conditions, and if left untreated, it can progress to more severe liver diseases, including cirrhosis and liver cancer. Despite its prevalence, there are numerous myths surrounding NAFLD that cause confusion and prevent proper management. Here, we will debunk some of these myths with facts and research-based insights.

10 Myths About Non-Alcoholic Fatty Liver Disease (NAFLD)
Myth 1: NAFLD is a rare condition.
Fact: NAFLD is not rare; it’s one of the most common causes of chronic liver disease globally, and India is no exception. A report by the Indian National Association for Study of the Liver (INASL) suggests that about 25-30% of the adult population in urban areas is affected by NAFLD, with higher prevalence rates among people with obesity and type 2 diabetes.
Myth 2: Only obese people can develop NAFLD.
Fact: While obesity is a major risk factor, even people with a normal body mass index (BMI) can develop NAFLD. This is known as lean NAFLD. Studies indicate that 10-20% of individuals with NAFLD are of normal weight but may have underlying metabolic issues such as insulin resistance, high cholesterol, or a sedentary lifestyle. (Source)
Myth 3: NAFLD will always progress to liver failure.
Fact: NAFLD does not always lead to liver failure. In fact, it can be managed and even reversed, especially in its early stages. By making lifestyle changes such as adopting a healthier diet and increasing physical activity, liver fat can be reduced, preventing progression to more severe stages like non-alcoholic steatohepatitis (NASH) or cirrhosis.

Myth 4: NAFLD causes noticeable symptoms early on.
Fact: One of the reasons NAFLD is so dangerous is that it is often asymptomatic in its early stages. Many people with NAFLD are unaware they have the condition until it’s detected through routine blood tests or imaging studies. Symptoms like fatigue, abdominal pain, and jaundice typically only appear when the disease progresses to more serious stages, such as NASH or cirrhosis. (Source)
Myth 5: NAFLD is not a serious condition.
Fact: NAFLD is a serious condition that can lead to life-threatening complications. According to the World Journal of Gastroenterology, around 20% of people with NAFLD progress to NASH, which involves liver inflammation and damage. NASH can lead to liver fibrosis, cirrhosis, and even liver cancer if left untreated. (Source)
Myth 6: Drinking coffee or taking certain supplements can cure NAFLD.
Fact: While there is some evidence that coffee consumption may reduce liver inflammation, there is no cure for NAFLD solely through diet or supplements. The best approach to manage NAFLD is a combination of weight loss, a healthy diet, and regular exercise. Certain supplements like vitamin E may help in specific cases, but they are not a standalone cure.
Myth 7: NAFLD is primarily caused by a high-fat diet.
Fact: NAFLD is more closely linked to excess calories and insulin resistance rather than just dietary fat. A diet high in refined carbohydrates, sugary beverages, and processed foods is more likely to contribute to NAFLD than dietary fats. Research published in the Indian Journal of Endocrinology and Metabolism shows that high fructose consumption is a major factor in the development of NAFLD. (Source)
Myth 8: NAFLD can be easily diagnosed through symptoms.
Fact: As mentioned, NAFLD often has no symptoms, which means it cannot be diagnosed based on how someone feels. The condition is typically diagnosed through liver function tests, ultrasound, or more advanced imaging techniques like MRI. In some cases, a liver biopsy may be required for a definitive diagnosis.
Myth 9: You cannot reverse liver damage caused by NAFLD.
Fact: Early-stage liver damage from NAFLD can be reversed with lifestyle changes. Studies show that losing just 5-10% of body weight can significantly reduce liver fat and inflammation, potentially reversing NAFLD. However, if NAFLD progresses to advanced fibrosis or cirrhosis, the damage becomes irreversible, making early intervention critical.
Myth 10: People with NAFLD should avoid all fats in their diet.
Fact: Not all fats are harmful for people with NAFLD. In fact, unsaturated fats found in foods like olive oil, avocados, and nuts are beneficial for liver health. It is more important to limit saturated fats, trans fats, and refined sugars, which contribute to insulin resistance and liver fat accumulation.
FAQs on Non-Alcoholic Fatty Liver Disease (NAFLD)
Q1: Is NAFLD related to diabetes?
A1: Yes, NAFLD is closely linked to type 2 diabetes. People with insulin resistance are at higher risk of developing NAFLD, and up to 70% of diabetics may have fatty liver disease.
Q2: Can children develop NAFLD?
A2: Yes, NAFLD is increasingly common in children, especially those who are overweight or obese. According to the Indian Academy of Pediatrics, NAFLD affects 3-10% of children in India, with higher rates in urban areas.
Q3: What tests are used to diagnose NAFLD?
A3: NAFLD is typically diagnosed using blood tests (liver function tests), ultrasound, CT scans, or MRI. A liver biopsy may be required in advanced cases to determine the extent of liver damage.
Q4: Does losing weight help NAFLD?
A4: Yes, weight loss is one of the most effective treatments for NAFLD. Studies show that losing 5-10% of body weight can significantly reduce liver fat and inflammation, and in some cases, reverse NAFLD.
Q5: Is NAFLD contagious?
A5: No, NAFLD is not a contagious disease. It is a metabolic condition influenced by diet, lifestyle, and genetic factors, but it cannot be transmitted from person to person.
Conclusion
Non-alcoholic fatty Liver Disease (NAFLD) is a growing health issue in India, largely driven by rising rates of obesity, type 2 diabetes, and sedentary lifestyles. By debunking these common myths, we hope to raise awareness and encourage people to seek appropriate medical advice and adopt healthier lifestyles. Early diagnosis and lifestyle changes can help manage and even reverse NAFLD, preventing it from progressing to more severe liver conditions.
