Obesity is a medical condition that impacts metabolism, hormone balance, and overall health. It encompasses much more than just physical appearance.
Obesity contributes to nearly 20% of global cancer cases.
India is facing a silent epidemic, and it’s not an infectious disease, but obesity. Once dismissed as a problem of the West, obesity is now one of the biggest public health concerns at home, driving early-onset diabetes, hypertension, fertility issues, and even cancer. The scale of the crisis is staggering, with children and young adults increasingly at risk. Experts say this is no longer about appearance or lifestyle choices, but about a systemic health threat that requires urgent attention.
Obesity Is Beyond Weight
“Obesity is a medical condition that affects metabolism, hormone balance, and long-term health. It is far more than physical appearance,” explains Dr. Raj Palaniappan, Director & Lead Surgeon, Institute of Bariatrics, Apollo Hospitals, Chennai. He explains that while Body Mass Index (BMI) is a common tool to classify weight, it doesn’t tell the whole story.
“Many young women have a ‘normal’ BMI but excess central fat, which is metabolically active and closely linked to insulin resistance, PCOS, and infertility,” he notes.
Data from the Apollo Health of the Nation 2025 report adds urgency. Sixty-one per cent of adults screened are obese, and 18% are overweight. Among students, 8% in primary school and 28% in college are already living with obesity.
Alarming Rise Among the Young
The profile of patients seeking help has shifted. “Two decades ago, most were middle-aged or older. Now, only 35% fall in that category. Obesity in 20- and 30-year-olds has jumped to nearly 25–30%,” says Dr. Palaniappan. The consequences are immediate. Prediabetes now affects 30% of people in their 20s–30s, and type 2 diabetes is striking as early as age 30.
“Comorbidities like hypertension, fatty liver disease, and even hormonal imbalances are appearing younger than ever before. If left unchecked, obesity can significantly shorten lifespan and reduce quality of life,” he warns.
Why Obesity Awareness Isn’t Enough
Obesity is not simply about willpower. Genetics, hormonal influences, poor sleep, stress, medications, and even gut health all play a role. “Diet and exercise account for only 30–35% of risk,” says Dr. Palaniappan. “That is why awareness alone isn’t enough. We need structured support and systemic change.”
Treatment and the Road Ahead
Bariatrics today goes far beyond surgery. New drug therapies, endoscopic procedures, and lifestyle interventions are transforming care. “But no treatment can replace the foundation of a healthy lifestyle,” says Dr. Palaniappan. “Without diet, physical activity, and stress management, results are short-lived.”
Obesity is no longer a personal struggle. Turning the tide on obesity will take courage, coordination, and consistency, but the cost of inaction will be far greater.
