Sedentary lifestyle, increasing screen time, prolonged desk job and junk diets fuel a fatty liver epidemic among India's youth
Once considered a condition of the elderly,
non-alcoholic fatty liver disease
(
NAFLD
) is now increasingly affecting young adults in India, particularly those in sedentary professions, posing a significant public health challenge.
Non-alcoholic fatty liver disease (NAFLD), now reclassified as metabolic dysfunction-associated steatotic liver disease (MASLD), is emerging as a significant health concern among young Indians, especially those engaged in sedentary occupations. Recent studies indicate a sharp rise in prevalence, with lifestyle factors such as prolonged sitting, poor dietary habits, and lack of physical activity being primary contributors.
"A study conducted by the University of Hyderabad revealed that over 80% of
IT professionals
suffer from MASLD, with 71% classified as obese and 34% diagnosed with
metabolic syndrome
. These findings underscore the impact of sedentary work environments and unhealthy lifestyles on liver health." Dr. Ankur Garg, Director & Senior Consultant, Centre for Liver-GI Diseases and Transplantation (CLDT), Aakash Healthcare.

The high prevalence of MASLD among IT professionals is a wake-up call. The combination of long working hours, physical inactivity, and poor dietary choices is taking a toll on the younger workforce.
A Silent Progression
NAFLD often develops quietly, with fat gradually accumulating in the liver. In its early stages, it may not cause any noticeable symptoms, making it difficult to detect without medical screening. However, the disease can escalate to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, or even liver cancer if left untreated.
'The liver is a resilient organ, but this resilience often means that damage goes unnoticed until it's too late. By the time patients come to us with symptoms like fatigue, abdominal discomfort, or unexplained weight loss, significant damage may already have occurred.' Dr. Amit Miglani, Director & HOD – Gastroenterology, Asian Hospital.
Not Just the Obese
While obesity, diabetes, and high cholesterol remain common risk factors, doctors are observing an increasing number of NAFLD cases among non-obese individuals. This emerging trend points to the multifactorial nature of the disease, with genetics, insulin resistance, and visceral fat playing critical roles.
"Fatty liver is no longer a disease confined to those who are overweight or diabetic. We're now diagnosing young, seemingly healthy professionals who barely show any symptoms until the condition is in an advanced stage. Many of our patients with fatty liver have a normal BMI but still show signs of metabolic dysfunction. This tells us that lifestyle choices and genetic predisposition can be just as damaging as excess weight.' Dr Abhishek Yadav, Consultant and Director - HPB and Liver Transplant Surgeon, Jupiter Hospital.
Lifestyle at the Core
Experts agree that the modern
sedentary lifestyle
is a major contributor to this rise. Prolonged sitting, lack of exercise, and diets high in processed foods all contribute to fat buildup in the liver. These habits are particularly prevalent among India's urban youth, whose workdays are dominated by screens and minimal physical movement.
'Sedentary behavior reduces insulin sensitivity, leading to insulin resistance—one of the key drivers of NAFLD. Unfortunately, our current work culture encourages long hours at desks with little regard for movement or nutrition.' added Dr. Ankur Garg.
The Gut-Liver-Brain Axis
Emerging research suggests that fatty liver disease, particularly in its advanced stages, can have a profound impact on neurological health. The liver plays a critical role in filtering toxins from the blood, and when its function is compromised, harmful substances like ammonia can accumulate and affect brain function, Dr Praveen Gupta, Principal Director & Chief of Neurology, Fortis Hospital said.
"There's growing evidence that the gut-liver-brain axis is significantly affected in patients with NAFLD. When liver health deteriorates, it can lead to subtle but chronic neurological disturbances that often go unnoticed until they worsen like memory lapses, difficulty concentrating, slowed thinking, mood changes, irritability or depression, and disturbed sleep patterns. In more severe cases, coordination problems or tremors may occur," Dr Gupta explained.
Call for Early Screening and Prevention
Health experts are urging primary care providers to incorporate liver function tests into routine health check-ups, particularly for those with risk factors. Policymakers are also being called upon to support public health awareness campaigns and fund research initiatives to better understand the spread and impact of NAFLD in India's diverse populations.
'We need to shift focus from treatment to prevention. Simple
lifestyle modifications
like 30 minutes of daily exercise, reducing processed food intake, and consuming more fiber-rich diets can go a long way in preventing fatty liver disease.' Dr Aakaar Kapoor, CEO & Lead Medical Advisor City XRay and Scan Clinic Pvt Ltd.
As India's youth faces the consequences of an increasingly sedentary lifestyle, experts stress that the time to act is now. Early intervention, lifestyle changes, and regular medical check-ups could help curb the growing burden of fatty liver disease before it becomes an irreversible crisis.

Air quality alert: Breathing is not guaranteed as smoke from Canada's infernos chokes cities from Toronto to New York
After days of a heavy grey haze blanketing southern Canada, air‑quality alerts were lifted across most of Québec and Ontario on Sunday, June 8. Environment Canada reported that a shift in wind patterns and light rainfall pushed smoke eastward, lifting warnings over major cities like Toronto , Ottawa, and Montréal, but pockets of poor air remain east of Montréal, south of Québec City, and in northern Ontario toward the Manitoba border How it all started by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like War Thunder - Register now for free and play against over 75 Million real Players War Thunder Play Now Undo Over 200 active wildfires in Manitoba and Saskatchewan churned out massive smoke plumes since early June, forcing thousands to evacuate and creating hazy skies across six provinces and the Northwest Territories. Those plumes raced across Canada and into the Eastern US, sparking health alerts in New York and parts of the Midwest. Live Events The science of the smoke Wildfire smoke is rich in PM2.5, tiny particles that penetrate deep into the lungs and the bloodstream. Researchers warn that even brief exposure can trigger asthma attacks, heart problems, and headaches, while cumulative exposure may increase risks of lung cancer and stroke. Some scientists have also raised alarms about toxic metals like arsenic and lead, released when fires spread through mining‑contaminated soils, intensifying long‑term risks. The human toll For north Toronto kindergarten teacher Emily Chan, the sky "smelled like burning plastic," and many of her students complained of sore throats. She recalled, 'We kept windows shut and cancelled outdoor playtimes.' In Montréal, retiree Marc Lecavalier said he felt his chest tighten during walks on the Île de la Cité, opting instead to sit inside with filtered air. Across the US border, in upstate New York, air‑quality warnings persisted on Sunday despite slight improvements, with the Adirondacks reaching an AQI of 150, "unhealthy for sensitive groups," while Finger Lakes briefly hit levels considered unhealthy for all. What's next Environment Canada expects a low‑pressure system to move through the Prairies and into Manitoba and northwestern Ontario by Monday, and bring much-needed rain to douse the fires. But as long as wildfires continue, the risk remains. Health officials still advise those in affected zones to stay indoors, avoid strenuous activity, and wear N95 masks if they must go outside. Experts predict smoke events will become more frequent and severe as climate change fuels longer fire seasons. For now, Canadians and Americans are getting a reminder: clean air isn't guaranteed.

Bridging health cover, mental healthcare in India
Mental health is finally getting the attention it has long deserved. The post-pandemic world has not only shifted how people think about well-being, but sparked a deeper sense of urgency around mental health, and how to plan for it. Globally, mental health conditions affect about one in five adults, with the World Health Organization estimating an annual productivity loss of over $1 trillion due to untreated mental health issues. In India, the conversation is gaining momentum and it's being reflected in both policy and consumer behaviour. Until a few years ago, health insurance was largely seen as a safeguard against physical illness or hospitalisation. That has changed. Following the Mental Healthcare Act, 2017 and IRDAI directive, mental health is now covered at par with physical illnesses across health insurance plans in India. This is not just a regulatory milestone — it signals a much-needed shift in how we define health. Changing landscape More importantly, this coverage is becoming more holistic. Today, most retail health insurance plans offer outpatient (OPD) benefits, either built-in or as optional add-ons. These allow for therapy, counselling, and psychiatric consultations — services central to mental healthcare but rarely require hospitalisation. Data tells us that people are using them. Our data shows over the past 2-3 years, mental health–related claims — including for therapy, stress counselling and anxiety medication — have risen by 30–50%. It reflects not just policy evolution but fundamental behavioural shift. More people are seeking professional help and using insurance to pay for it. Younger Indians lead Interestingly, the demand is being led by younger Indians. Those between 25-35 years are driving the highest search interest, policy uptake and mental health claims. This group, juggling career pressures, financial uncertainties and the demands of an always-on digital lifestyle, is showing greater openness to emotional support, particularly through app-based therapy and online mental health platforms. A closer look at the claims data shows anxiety disorders account for about 30–35% of mental health claims, followed by depression (25–30%), workplace stress and insomnia. Most of these are early to moderate cases, which signals another crucial trend: a growing comfort with seeking care before reaching crisis point. This is how real change begins — with early intervention. For women Women are significantly more likely to opt for policies that include mental health benefits — especially those aligned with life-stage transitions such as pregnancy, menopause or caregiving responsibilities. Emotional well-being during these phases is often under-acknowledged but deeply impactful. The rise in claims from women reflects broader cultural shift toward prioritising self-care often for the first time. Geographically, mental health insurance adoption is still concentrated in Tier 1 cities, accounting for more than 50% of the total uptake. These metros typically have better access to therapy networks, more progressive workplace policies and higher levels of digital literacy. That said, growing interest from Tier 2 cities points to a promising national trend — one where awareness is no longer limited to urban pockets. Workplaces, too, are undergoing a transformation. Whether through wellness programmes, access to therapists, or stress management workshops, mental health is beginning to find a place in the benefits conversation. No longer afterthought The best part of this conversation is mental health is no longer an afterthought. People are researching, asking and making insurance decisions with it in mind. But there's still a long way to go. Coverage is now widespread, but utilisation and awareness need to catch up. Many still don't know their plans include OPD therapy or cashless mental health services are an option. This is where the focus must lie — in building a system that is not only inclusive on paper but accessible in practice. The foundation is in place: regulation, product innovation and early adoption. What's needed next is education, empathy and a continued effort to normalise mental health as part of everyday healthcare planning. The message is simple: taking care of your mind is just as important as taking care of your body. And today, with the right insurance plan, you can do both, affordably and confidently.

Looking for the perfect perfume? Well, it's synthesized on your skin
Dr Abdul Ghafur, an infectious disease expert is swabbing skin and using genetic sequencing to analyse epidermal bacteria -- not for diagnosing diseases but to recommend personalized perfumes based on an individual's unique skin microbiome. "Understanding the skin's microbiome is revolutionising how we approach the choice of perfumes. It moves beyond simply picking a scent to a personalised, scientifically-backed approach that considers your unique body chemistry," Dr Ghafur said. In May, Dr Ghafur, who works at Apollo Hospitals in Teynampet, started Fragragenomics Biotech (P) Ltd to help people make the right perfume choices. He launched the company owing to his interest in perfumes, his knowledge of microbiomes, and his frustration with some of the world's most famous fragrances that failed on his body. "It was during my work on microbiomes during the pandemic that I found the reasons," he said. The skin is home to trillions of microorganisms, including bacteria and fungi, that comprise your skin microbiome. "When we think of microorganisms, we think they are all bad. That's not true. At least 99.99% of the bugs are either neutral or good for humans. Less than 0.001% cause diseases," he said. No two people have the same composition of skin microbes. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Preparado para todo con hasta 10 años de garantía Nissan X-Trail Obtén ofertas Undo These microbes interact with compounds in the sweat, oils, and dead skin cells, metabolising them into volatile organic compounds. "These compounds, not sweat itself, create a unique, natural body odour. This scent fingerprint is influenced by genetics, diet, lifestyle, environment, and hormones. So everyone has a unique body odour," he said. Distilling the right perfume depends a lot on this. While sight or sound might dominate our conscious experience, scent often triggers far more vivid recollections. The olfactory pathways in the brain are fascinating neural routes that allow us to perceive and interpret smells. Unlike sight or hearing, the sense of smell takes a direct path to the brain, often bypassing the thalamus, which is a relay station for most other sensory information. Dr Ghafur's passion drove him to visit numerous perfumeries both in India and abroad. "Many perfumers were happy to discuss science," he said. The global perfume market was valued at about $50-55 billion in 2024. It's projected to touch an estimated $77-88 billion by 2032-2033, with a CAGR of about 5.3% to 5.9%. So, any scientific advancement that can attract more customers or bring in new ones is generally well-received. Customers perceive perfumes as much more than just a pleasant smell. They are seen as complex compositions that can influence emotions, shape perceptions, trigger memories, and serve as a subtle yet powerful extension of one's identity. "I don't feel shy to ask my patients or colleagues about the perfumes they use. Or I simply tell them the flavours in their perfume. Some think I am entering their personal space, but once I discuss science, they seem interested," he said. A common complaint is that a perfume didn't last as long as expected. Over the past few months, he has been testing and discussing what kind of bacteria produces a strong body odour and the kinds of scent profiles that will suit them. For instance, bacteria such as Corynebacterium, Staphylococcus epidermidis, and Propionibacterium acnes feed on the proteins, fats, and oils in the sweat, especially in armpits, groin, and feet. They break these down into smaller, smelly molecules. When the "good" or neutral bacteria such as Micrococcus or Lactobacillus are thriving, they can help maintain a healthy skin environment, possibly by producing acids that inhibit odour-causing bacteria, or simply by not producing strong offensive smells themselves. He offers his patients tips on the top notes – the flavours that last for up to ten minutes, the middle notes, the ones that last for about four hours, and the base notes that will last for hours to days. The skin microbiome metagenomic test, of course, is not for everyone. "We can't tell everyone to go for testing. But we want to make them aware of how some volatile organic compounds work. The result is no one buys perfume after smelling a sheet of paper or during the two-hour layover at an airport," he said. Dr Ghafur has made a presentation about skin microbiomes in people with diabetes – how a systemic environment can lead to a less healthy, less diverse skin microbiome, contributing to specific body odours. "Many doctors were interested. They called back too," he said.
