According to our new research study on “Anti-obesity Drugs Market Forecast to 2031 –Global Analysis – by Type, Drug Class, Route of Administration, Application, Distribution Channel, and Geography,” the market is anticipated to grow from US$ 15.85 billion in 2024 and is projected to reach US$ 177.27 billion by 2031; it is expected to register a CAGR of 35.3% during 2025–2031. Mounting prevalence of obesity and increased awareness and demand for weight management solutions are contributing to the growing anti-obesity drugs market size. However, the side effects and safety concerns hamper the anti-obesity drugs market growth. Further, precision medicine and personalized anti-obesity drug regimens is expected to bring in new anti-obesity drugs market trends in the coming years.

In terms of revenue, North America dominated the market in 2024. It is estimated to dominate the global market during the forecast period. The US is the largest market for anti-obesity drugs in the world. Chronic wounds associated with diabetes include foot, venous, and pressure ulcers. According to The International Journal of Tissue Repair and Regeneration, active or healed venous ulcers occur in 1% of the US population. As per the National Diabetes Statistics Report 2020, a publication of the Centers for Disease Control and Prevention (CDC), 34.2 million people of all ages in the US have diabetes, and ~1 million diabetics develop a foot ulcer each year, while 6-7 million diabetes patients develop ulcers in their lifetime. Thus, the rising incidence of diabetes and chronic wounds leads to an increase in demand for wound dressing and contributes to the anti-obesity drugs market growth during the forecast period. Companies in the US are focused on expanding their presence by adopting organic and inorganic strategies. In October 2021, Medline Industries announced an investment of US$ 77.5 million to build a new distribution center in Kansas.

Anti-obesity Drugs Market Analysis

Expansion in Emerging Economies to Provide Market Opportunities in Future

According to a Lancet study published in July 2023, approximately 450 million adults in India are expected to be overweight or obese by 2050. In 2021, more than half of the world's adults who were classified as overweight or obese lived in India, with 180 million affected individuals; China, with 402 million; Brazil, with 88 million; Russia, with 71 million; Mexico, with 58 million; Indonesia, with 52 million; and Egypt, with 41 million.

According to the World Obesity Federation, Vietnam, Indonesia, and Bangladesh are experiencing rising obesity prevalence, with a rate of 6–9% in recent decades. The mounting prevalence of obesity in emerging countries due to urbanization, sedentary lifestyles, and dietary changes has increased the demand for anti-obesity drugs. A large segment of the population remains undiagnosed or untreated, offering an underpenetrated market for pharmaceutical companies to introduce new therapies and expand their reach. Eli Lilly is preparing to launch its weight-loss and diabetes drug, tirzepatide (marketed as Mounjaro for diabetes and Zepbound for obesity), in India, Brazil, and Mexico by 2026.

Brazil is enhancing healthcare infrastructure and obesity management programs, fostering a supportive environment for the introduction and reimbursement of new anti-obesity medications. In April 2024, Brazil opened a laboratory in Hortolândia, São Paulo State, dedicated to producing medications for diabetes and obesity, including liraglutide, an active ingredient found in Ozempic. The EMS-operated plant will also produce semaglutide, a key ingredient in Ozempic, which has a patent valid until March 2026 and is already under review by Agência Nacional de Vigilância Sanitária (ANVISA). With an investment of R$60 million (~US$ 10.93 million), this facility is the first of its kind in Brazil and supports the federal government's Health Economic-Industrial Complex initiatives.

According to the World Economic Forum, initial access to anti-obesity medications may be limited to private markets and out-of-pocket payments. Still, future insurance coverage and generic versions in middle-income countries could improve the accessibility of these medications. Thus, the rising obesity rates, supportive government initiatives, and product innovations are expected to create future growth opportunities for the market in emerging countries.
