Understanding Causes, Complications & Prevention
In today’s fast-paced world, where convenience often takes priority over health, obesity has silently grown into one of the most serious public health challenges we face. From young children to adults, millions struggle with excess weight, not just physically, but emotionally and socially as well.
People living with obesity often face social stigma, embarrassment, and reduced self-esteem. But beyond these visible effects lies a deeper issue—obesity is a complex disease that triggers a cascade of medical complications.
🌍 The Global Picture of Obesity
According to a 2021 report by the World Health Organization (WHO):
Over 2.9 billion adults were overweight.
Among them, 850 million were classified as obese.
Approximately 45 million children under the age of 5 were obese.
440 million children and adolescents (ages 5–19) were either overweight or obese.
Even more alarming is the fact that obesity has tripled globally since 1975, and it is now responsible for over 4 million deaths every year. Data also suggests that people with obesity tend to have shorter lifespans compared to those with healthier body weights.
🧠 What Exactly Is Obesity?
Obesity is more than just being overweight—it’s a chronic disease involving excessive body fat that increases the risk of other health problems. While all obese individuals are overweight, not all overweight individuals are obese.
The most common tool to determine this is the BMI (Body Mass Index):
BMI = Weight (kg) / Height (m)²
BMI Categories:
Normal weight: Less than 25
Overweight: 25 or more
Obese: 30 or more
Obesity typically starts with fat accumulation around the abdomen and then gradually spreads throughout the body if left unaddressed.
🔍 What Causes Obesity?
Obesity doesn’t happen overnight. It’s the result of an energy imbalance—when calorie intake consistently exceeds calorie burn. Here are the primary contributing factors:

🛋️ Physical inactivity
🍟 Frequent snacking or irregular meals
💊 Medication side effects (e.g., antidepressants, steroids)
😞 Psychological factors (stress, depression, emotional eating)
