The global obesity treatment market size was valued at USD 15.92 billion in 2024 and is projected to reach USD 60.53 billion by 2030, growing at a CAGR of 22.31% from 2025 to 2030. This strong growth trajectory reflects the increasing burden of obesity worldwide and the growing need for effective treatment solutions. The market is primarily driven by the rising global prevalence of obesity and its associated comorbidities, including diabetes, cardiovascular diseases, and hypertension, which place significant pressure on healthcare systems and drive demand for medical intervention.

Growing awareness of obesity as a chronic and progressive condition that requires long-term medical management has led to increased demand for effective pharmacological treatments. According to the World Health Organization (WHO), obesity is defined as a chronic disease characterized by excessive fat accumulation that adversely affects health, increasing the risk of type 2 diabetes, cardiovascular diseases, certain cancers, and a reduced quality of life. As of 2022, approximately 2.5 billion adults were overweight, of which 890 million were classified as obese, along with 37 million children under the age of five being overweight. These figures highlight the widespread nature of the condition and the urgency for effective prevention and treatment strategies. Obesity is largely driven by factors such as unhealthy dietary patterns, physical inactivity, and increasingly obesogenic environments that promote sedentary lifestyles and high-calorie food consumption.

Although obesity is largely preventable and manageable through healthy eating habits, regular physical activity, and lifestyle modifications, effective management often requires a comprehensive and multidisciplinary approach. The WHO emphasizes the need for coordinated global action, including regulatory policies related to food production, labeling, and marketing, as well as stronger healthcare interventions to reduce obesity-related health risks. As obesity prevalence continues to rise across both developed and developing regions, companies offering innovative, effective, and accessible obesity treatment solutions are expected to benefit from significant market expansion over the forecast period.

Key Market Trends & Insights:

• The North America obesity treatment market dominated the global industry with a revenue share of 73.39% in 2024, reflecting the region’s high prevalence of obesity, strong healthcare infrastructure, and widespread access to advanced medical treatments. Favorable reimbursement frameworks, early adoption of innovative obesity drugs, and increasing awareness of obesity as a chronic medical condition have further reinforced North America’s leading position in the global market.

• Based on drug class, the GLP-1 receptor agonists segment accounted for the largest revenue share of 80.19% in 2024. This dominance is primarily attributed to the high efficacy of these therapies in supporting weight management, improving glycemic control, and reducing obesity-related health risks. The growing acceptance of GLP-1 receptor agonists among healthcare professionals and patients, along with ongoing clinical advancements, has significantly driven their widespread use.

• Based on the route of administration, the parenteral segment captured the largest revenue share at 82.20% in 2024. The strong preference for injectable formulations is linked to their proven effectiveness, controlled dosing, and sustained therapeutic outcomes. Parenteral administration continues to be widely adopted in clinical settings due to its reliability and established treatment protocols.

• Based on distribution channels, the retail pharmacies segment held the largest revenue share of 55.08% in 2024. This leading position is supported by the broad availability of obesity treatment medications through retail pharmacy networks, ease of patient access, and the increasing role of pharmacists in patient education, prescription fulfillment, and ongoing treatment management.
