Understanding the Obesity Epidemic: A Global Challenge
Obesity is characterized by excessive body fat that poses significant health risks, including heart disease, diabetes, stroke, and certain types of cancer. According to the World Health Organization (WHO), the global obesity rates have tripled since 1975. As of recent reports, more than 650 million adults worldwide are classified as obese, with an increasing number of children and adolescents also being affected. The rising prevalence of obesity is due to various factors, including poor dietary habits, sedentary lifestyles, genetic predisposition, and socioeconomic factors.
The rapid rise in obesity rates has led to a surge in demand for interventions that can help individuals manage and reduce their body weight. Anti-obesity drugs, as part of a broader obesity management approach, have grown in popularity. These drugs are designed to either reduce appetite, inhibit fat absorption, or enhance metabolic rate, providing an additional tool for those struggling with obesity.
