New York, NY – July 09, 2025 – Global Anti-obesity Drugs Market size is forecasted to be valued at US$ 412.9 Billion by 2034 from US$ 26.3 Billion in 2024, growing at a CAGR of 31.7% during the forecast period 2025 to 2034. In 2024, North America led the market, achieving over 46.40% share with a revenue of US$ 12.2 Billion.
A new generation of anti-obesity drugs has been introduced to combat the growing global obesity epidemic, offering a promising solution for millions affected by weight-related health conditions. With obesity rates continuing to rise worldwide impacting over 650 million adults, according to the World Health Organization this innovative pharmaceutical advancement is expected to deliver clinically proven weight reduction results alongside improved metabolic health outcomes.
The newly approved drug operates through appetite suppression and delayed gastric emptying, supporting sustained weight loss when combined with diet and lifestyle interventions. Clinical trials have demonstrated significant outcomes, with patients achieving up to 15–20% reduction in body weight over a treatment course of 12 to 18 months. The medication is administered through a once-weekly subcutaneous injection and is approved for adults with a body mass index (BMI) ≥30, or ≥27 with comorbidities such as type 2 diabetes or hypertension.
The drug complies with regulatory standards including those set by the U.S. FDA and the European Medicines Agency (EMA), ensuring safety and efficacy. It is projected to expand access to effective obesity management across primary care settings and specialty clinics.
With chronic obesity posing a major burden on healthcare systems, this anti-obesity drug is expected to play a critical role in reversing the tide of metabolic disease and reducing associated long-term healthcare costs.

Segmentation Analysis
- Drug Type Analysis: In 2024, prescription anti-obesity drugs led the market with an 82.3% share, driven by increasing demand for clinically validated therapies. GLP-1 receptor agonists like semaglutide (Wegovy) and liraglutide (Saxenda) have gained prominence for enabling 15–20% weight loss in patients. Their success reflects a shift toward treating obesity as a chronic disease, particularly for individuals with a BMI ≥30 or ≥27 with comorbidities such as diabetes, heart disease, or hypertension.
- Mechanism of Action Analysis: Peripherally acting drugs accounted for 58.5% of the global anti-obesity drugs market in 2024. These drugs, such as orlistat, act within the gastrointestinal tract to inhibit fat absorption, minimizing central nervous system side effects. Their targeted mechanism and favorable safety profile appeal to a broader patient base. Orlistat remains widely used due to its long-standing efficacy and tolerability, although gastrointestinal side effects, such as oily stools, are commonly reported.
- Route of Administration Analysis: Injectable drugs dominated the route of administration segment in 2024, contributing 75.9% of total market revenue. This is largely attributed to the superior clinical outcomes of GLP-1 receptor agonists like semaglutide (Wegovy) and tirzepatide (Zepbound). The launch of Wegovy in India and rapid uptake of Eli Lilly’s Mounjaro reflect rising demand for injectables. These formulations provide sustained drug delivery, improve patient adherence, and remain the preferred choice over emerging oral alternatives due to higher efficacy.
- Patient Type Analysis: Adults represented the largest patient segment, contributing 95.3% to the anti-obesity drug market in 2024. High obesity prevalence among adults—such as 42% in the U.S.drives this dominance. Obese adults often present with comorbidities like hypertension (58%) and diabetes (23%). New research also links anti-obesity drugs like semaglutide with reduced dementia risk in type 2 diabetes patients, particularly in older women, expanding their use beyond weight loss to broader chronic disease management.
- Distribution Channel Analysis: Retail pharmacies led the distribution channel segment with a 56.7% market share in 2024. Their dominance is supported by widespread availability, personalized services, and integration with digital platforms. Retail chains and independent pharmacies provide patients with easy access to prescription and OTC anti-obesity drugs, along with support services like counseling and refill management. Online ordering and home delivery further enhance patient adherence, making retail pharmacies a central point of access for obesity treatment.

Regional Analysis
In 2024, North America dominated the global anti-obesity drugs market, accounting for a 46.4% share. This leading position is attributed to the region’s high obesity prevalence, well-established healthcare infrastructure, and substantial healthcare spending. The United States remains a key contributor, driven by the widespread adoption of GLP-1 receptor agonists such as semaglutide and tirzepatide.
According to the 2024 KFF Health Tracking Poll, approximately 12% of U.S. adults reported having used a GLP-1 agonist, with 6% currently on treatment. Usage is significantly higher among individuals with specific health conditions 43% among those with diabetes, 25% with heart disease, and 22% of those recently diagnosed as overweight or obese. Public awareness has also increased, with 32% of adults stating they have heard “a lot” about these medications, up from 19% in July 2023.
The Asia Pacific region is projected to register the highest compound annual growth rate (CAGR) over the forecast period. Rising obesity rates across major countries including China, India, and Japan are fueling demand for effective pharmacological weight management solutions. According to Novotech, China ranks second globally for obesity clinical trials despite a relatively lower obesity rate of 6%, compared to 31% in Australia and 40% in the U.S. The recent launch of Wegovy in India and the expected introduction of generic semaglutide post-2026 are anticipated to enhance accessibility and drive further market expansion across the region.
Emerging Trends
- Rapid uptake of GLP 1 receptor agonists: Use of GLP 1 drugs (semaglutide, liraglutide) in U.S. adolescents increased 504–588% from 2020 to 2023 following FDA approvals and AAP guidelines. This reflects expanding adoption in younger age groups.
- Growing real-world safety and outcomes monitoring: NIH’s NIDDK held a 2025 workshop on using real-world evidence (EHR, claims) to measure long term benefits and rare side effects of GLP 1 therapies reflecting heightened post market surveillance.
- Shift toward dual/triple agonist therapies: Combined drugs like tirzepatide (dual GIP/GLP 1) and cagrilintide+semaglutide (triple agonist) are demonstrating 15–20% weight loss in clinical trials, signaling next generation treatment trends.
- Move toward oral alternatives: Orforglipron, an oral GLP 1 agonist in Phase III (2025), has produced ~8% weight loss in 40 weeks, with efficacy approaching injectables.
- Regulatory scrutiny of unapproved formulations: FDA warnings highlight risks from illegally sold unapproved GLP 1 products labeled “for research,” emphasizing need for patient safety.
Use Cases
- Adolescent obesity management: In 2024, first-time semaglutide prescriptions among U.S. teens aged 12–17 rose from 9.9 to 14.8 per 100,000 (~50% increase year-over-year). Use among obese adolescents (no diabetes) reached 0.9%, nearly double 2023’s 0.5%.
- Chronic disease prevention in adults: Semaglutide (Wegovy) now carries FDA indication to cut risk of major cardiovascular events: 6.5% vs. 8% in placebo in a 17,600-patient trial.
- Weight loss in non diabetic adults: Clinical data indicate GLP 1 agonists reduce body weight by 6.1–7.4% in overweight adults without diabetes greater than the 4–6.2% seen in those with diabetes.
- Long‑term adherence patterns: One-year persistence: 47.1% for semaglutide (Ozempic) vs. 19.2% for liraglutide (Saxenda), indicating adherence impacts efficacy.
- Obesity rate impact at population level: U.S. adult obesity fell ~2% from 2020 to 2023, coinciding with ~6% of U.S. adults using GLP-1 drugs.
Conclusion
The global anti-obesity drugs market is undergoing rapid transformation, driven by clinical innovation, regulatory support, and rising global demand. With the introduction of highly effective therapies like GLP-1 and dual/triple agonists, significant weight loss and chronic disease risk reduction are now achievable.
The market, valued at USD 26.3 billion in 2024, is projected to reach USD 412.9 billion by 2034, reflecting a strong 31.7% CAGR. Growing adoption across adults and adolescents, expanding access through retail and online channels, and promising trends in oral formulations position anti-obesity drugs as a cornerstone in future global metabolic health management.
