Anti-Obesity Drugs Market to Grow at a CAGR of 32.10% During 2026-2035, Aided by the Rising Obesity Rates Across the 8 Major Markets

Anti-Obesity Drugs Market Overview

Anti-obesity drugs are recommended for individuals with a body mass index (BMI) greater than 30 or people with a BMI more than 27 and having serious medical conditions (diabetes or high blood pressure) linked to obesity. These drugs help in reducing around 3% to 12% of the total body weight of the patient in a year. The rising incidence of obesity and the increasing focus on weight management are the primary drivers of the market. The surge in regulatory approvals of new anti-obesity drugs is anticipated to bolster the market demand. Moreover, the growing adoption of combination therapies, innovation in drug development, and rising awareness of obesity-related health risks are poised to influence the market dynamics in the forecast period.

Key Findings

• Obesity affects a vast and growing population, with over 1 billion people living with obesity worldwide, comprising roughly 880 million adults and 159 million children and adolescents, and around 3 billion people either overweight or obese, sustaining strong demand for anti-obesity treatment.
• The oral GLP-1 era has arrived, with the first oral GLP-1 pills for weight management reaching the market in late 2025 and 2026, expanding options beyond weekly injections and potentially broadening access to obesity pharmacotherapy.
• Obesity is one of the fastest-growing therapeutic areas, with GLP-1 based therapies, both injectable and oral, projected to exceed USD 100 billion in annual sales by 2030 and drawing major investment and dealmaking across the industry.

Anti-Obesity Drugs Market Demand Drivers

According to the NCD Risk Factor Collaboration (NCD-RisC),  over 1 billion people are living with obesity worldwide, comprising about 880 million adults and 159 million adolescents and children between the ages of 5 and 19 years. The World Obesity Federation also states that approximately 3 billion individuals are either overweight or obese, indicating the increasing risk of obesity in several countries in the world. This rising rate of obesity due to sedentary lifestyles, unhealthy eating habits, and genetic factors, is expected to fuel the market demand in the forecast period.
