Rising obesity among young people increases the risk of heart disease and diabetes - Dr Saurabh Bansal

1. What are the major drivers of obesity in younger people, and does age matter?

Obesity among younger people is largely driven by sedentary lifestyles, excessive screen time, unhealthy eating habits, and reduced physical activity. Easy access to processed foods, sugary drinks, and irregular sleep patterns further contributes to the problem.

Age may seem less important initially, but obesity that begins in childhood or adolescence often continues into adulthood. Early weight gain significantly increases the risk of metabolic disorders later in life, including diabetes, hypertension, and heart disease.

2. Why is obesity becoming a major driver of heart attacks in India?

Obesity significantly increases the risk of several conditions that directly affect heart health. Excess body fat especially abdominal fat can lead to high blood pressure, high cholesterol, and insulin resistance.

These factors damage blood vessels over time. In India, changing lifestyles, reduced physical activity, and calorie-dense diets have increased obesity rates even among younger populations. This combination raises the risk of developing heart disease and experiencing heart attacks at a relatively younger age.

3. Where does heart disease actually start?

Heart disease often begins silently many years before symptoms appear. It usually starts with the gradual buildup of fatty deposits, known as plaque, inside the arteries that supply blood to the heart. This process, called atherosclerosis, narrows and stiffens the arteries, reducing blood flow. Risk factors such as obesity, high cholesterol, smoking, diabetes, and high blood pressure can accelerate this process. Over time, plaque buildup may lead to blockages that trigger heart attacks or other cardiovascular complications.

4. What is the link between obesity, diabetes, and heart disease?

Obesity plays a central role in the development of both diabetes and heart disease. Excess body fat particularly around the abdomen can lead to insulin resistance, increasing the risk of type 2 diabetes.

Diabetes further damages blood vessels and increases inflammation, making arteries more vulnerable to blockage. When combined with high cholesterol and high blood pressure conditions commonly associated with obesity the risk of heart disease increases significantly.

5. How can obesity be prevented in young children?

Preventing obesity in children requires encouraging a balanced lifestyle from an early age. Parents should focus on nutritious meals that include fruits, vegetables, whole grains, and balanced portions rather than processed or high-sugar foods. Regular physical activity, outdoor play, and limited screen time are equally important. Establishing consistent sleep routines and involving children in active family activities can also help. Healthy habits developed early in life play a crucial role in maintaining a healthy weight.

6. Can the Indian diet be blamed for rising obesity?

The traditional Indian diet itself is not the primary cause of obesity. In fact, many traditional meals are balanced and rich in whole grains, lentils, vegetables, and spices that support good health.

The problem arises when these traditional foods are replaced with highly processed, fried, or sugar-rich items. Increased consumption of fast food, refined carbohydrates, and sugary beverages combined with sedentary lifestyles has contributed more significantly to rising obesity rates.

7. What are three key ways to prevent obesity?

Three simple strategies can help prevent obesity. First, maintain a balanced diet that includes whole foods, fruits, vegetables, lean proteins, and controlled portion sizes. Second, engage in regular physical activity such as walking, sports, or exercise for at least 30–60 minutes daily.

Third, adopt healthy lifestyle habits including adequate sleep, reduced screen time, and effective stress management. Together, these measures help maintain a healthy weight and reduce the risk of chronic diseases.
