Why is Fatty Liver Disease On The Rise Among Non-Drinkers? Expert Weighs In

For decades, a fatty liver was seen as a drinker's diagnosis, something that turned up after years of heavy indulgence. That assumption no longer holds. Doctors across India are now seeing the condition in people who barely touch alcohol. The disease has been renamed accordingly. What was once called non-alcoholic fatty liver disease is increasingly referred to as metabolic dysfunction-associated steatotic liver disease, or MASLD — a mouthful, but one that better reflects what's actually happening: the liver accumulating fat not because of what someone drinks, but because of how their metabolism is functioning. 

To understand this better, we reached out to Air Cmde (Dr) Bhaskar Nandi, Director and Head, Gastroenterology, Hepatology and Endoscopy, Sarvodaya Hospital, Sector-8, Faridabad, and Dr Tushar Tayal, Associate Director, Internal Medicine, CK Birla Hospital Gurugram. 

Why is Fatty Liver On The Rise Among Non-Drinkers?

Let us straightaway get to the main point and understand why fatty liver is rising among non-drinkers. Dr Tayal says, “The usual suspects are familiar enough: insulin resistance, obesity, high triglycerides, sedentary living. But hepatologists point to something less obvious: the sheer amount of fructose and refined carbohydrate in the average urban Indian diet. Packaged snacks, sweetened beverages, and the ubiquitous evening chai with biscuits all feed a slow, silent process. The liver, tasked with processing this excess sugar, converts what it cannot use into fat and stores it. Over years, this builds into inflammation, then scarring, and in some cases, cirrhosis, all without a single drink involved.”

Adding to this, Dr Nandi says, “The primary reason is the increasing prevalence of obesity, especially excess abdominal fat, along with type 2 diabetes, prediabetes, high cholesterol, and high blood pressure. A sedentary lifestyle, diets rich in processed foods, sugary beverages, refined carbohydrates, and unhealthy fats contribute to fat accumulation in the liver. Even individuals who appear lean can develop fatty liver if they have poor metabolic health, unhealthy eating habits, or a genetic predisposition.”

According to The Cleveland Clinic, these are the symptoms of MASLD:

• An ache in your upper right abdomen, where your liver is located.
• Extreme fatigue and weakness.
• Loss of appetite.
• Swollen belly.
• Unexpected weight loss.
• Yellowing of your skin and eyes (scleral icterus).

What Are The Misconceptions Related to Fatty Liver?

There are various misconceptions surrounding fatty liver. On this note, Dr Tayal sheds light busts some of these myths:

1. There's a persistent myth worth dismantling: a fatty liver only matters if someone ‘feels’ unwell. In reality, the condition is often asymptomatic until it has progressed significantly, which is precisely what makes it dangerous. Fatigue, mild discomfort under the right ribs, or nothing at all can accompany early-stage disease. Routine blood tests or ultrasounds, often ordered for unrelated reasons, are how many people first learn of it.

2. Another misconception is that thinness offers protection. Doctors increasingly describe ‘lean MASLD’: a fatty liver in people with a normal body mass index, driven instead by poor muscle mass, visceral fat, or genetic predisposition. South Asians, in particular, are known to carry fat viscerally even at lower weights, making this population especially vulnerable regardless of how they look on the outside.

How To Treat Fatty Liver Disease

Fatty liver can be a serious cause of concern. Dr Nandi says if left untreated, it can progress to liver inflammation, fibrosis, cirrhosis, and in some cases, liver cancer. “People with fatty liver are also at a higher risk of cardiovascular disease, which remains the leading cause of death in these patients,” he adds.

So what is the way ahead? Dr Nandi answers, “The good news is that fatty liver can often be reversed with timely intervention. Weight loss, regular physical activity, a balanced diet rich in fruits, vegetables, whole grains, and lean protein, along with effective control of diabetes and cholesterol, can significantly improve liver health. Individuals with obesity, diabetes, or persistent abnormal liver function tests should undergo regular screening, as early detection and lifestyle modifications remain the cornerstone of treatment.”

Adding to this, Dr Tayal says, “The reversal, fortunately, tends to be more encouraging than the diagnosis suggests. Weight loss of even five to ten per cent, reduced sugar intake, and regular physical activity can meaningfully reduce liver fat, sometimes within months. What clinicians stress most is early detection, not waiting for symptoms that may never announce themselves clearly, but treating routine liver enzyme checks as seriously as blood sugar or cholesterol screening has come to be treated.”

Conclusion

The rise of fatty liver disease among non-drinkers is a crucial reminder that modern dietary habits and poor metabolic health can harm your liver as much as alcohol. Fatty liver is a condition which often progresses silently without any physical symptoms. Therefore, it is important to prioritize routine screenings and blood tests to catch it early. By making good lifestyle changes such as following a balanced diet, weight management, and regular exercise, this early-stage liver damage can be effectively managed as well as reversed.
