The Hunger Games: Obesity and Weight Management Resources

Introduction

Obesity is a substantial public health crisis in the United States and internationally, with the prevalence increasing rapidly in numerous industrialized nations.¹ A report from the World Obesity Federation predicted that by 2035, over 4 billion people (51% of the world's population) will be classified as overweight or obese.²

Pharmacists and pharmacy technicians have recently become more important in the care of patients with obesity, owing to the rise in popularity and efficacy of weight-loss drugs. Pharmacists play a key role in helping patients understand treatment options and potential efficacy, providing administration guidance, and counseling about management of possible side effects. Pharmacy technicians can assist with navigating insurance benefits for weight-loss drugs and accessing medication assistance programs.

Classification

Among several classifications and definitions for degrees of obesity, the following is widely used:³

• Overweight-BMI greater than or equal to 25 to 29.9 kg/m²
• Obesity class I-BMI 30 to 34.9 kg/m²
• Obesity class II-BMI 35 to 39.9 kg/m²
• Obesity class III-BMI greater than or equal to 40 kg/m² (also termed severe, extreme, or massive obesity)
