Anti-obesity Drugs Market Size, Share & Industry Analysis, By Type (Prescription Drugs and OTC Drugs), By Distribution Channel (Hospital Pharmacy and Retail and Online Pharmacy), and Regional Forecast, 2024-2032

The global anti-obesity drugs market size was valued at USD 4.51 billion in 2023 and is projected to grow from USD 6.15 billion in 2024 to USD 37.94 billion by 2032, exhibiting a CAGR of 25.5% during the forecast period (2024-2032). 

As per World Health Organization (WHO), overweight and obesity are defined as abnormal or excessive accumulation of fat that increases the risk of other chronic diseases such as insulin resistance, glucose intolerance, hypertension, sleep apnea, diabetes mellitus, arthritis, gall bladder diseases, and certain types of cancers. The significant rise in the prevalence rate of obesity has led to a large patient population suffering from debilitating and chronic conditions that severely affect the patient's daily functioning and have severe implications on their mortality.

According to the a 2023 estimate by the Centers for Disease Control and Prevention (CDC), more than 684,000 obesity-associated cancers occur in the U.S. each year, of which more than 210,000 are men and 470,000 are women. Further, it stated that breast cancer is the most common obesity-associated cancer among women, whereas it is colorectal cancer among men. Creating more awareness of the dangers of this chronic disease and the high healthcare expenditure associated with it, especially among the younger generation, will lead to the greater adoption of therapeutics for early and preventive care of the disease. All these factors are anticipated to drive the growth of the market over the forecast period.

Furthermore, the COVID-19 pandemic negatively influenced the market growth. The expansion was hampered in 2020 due to a reduction of in-person visits to healthcare professionals and the shutdown of non-essential healthcare services. In 2021, the increasing use of telemedicine in place of ‘in-person’ hospital visits and the utilization of online pharmacies to procure repeat medications minimized the adverse impact on the market. The market experienced growth post-pandemic with ease of COVID-19 regulations and increased prevalence rate of obesity across the globe. In 2023, the market was expected to witness substantial growth attributed to new product launches, the promising pipeline of prominent companies. These factors are expected to propel the growth of market during the forecast period.

Anti-obesity Drugs Market Trends

Increasing Awareness Regarding Obesity Treatment Creating Growth Opportunities in the Market

Over the past few decades, the prevalence rate of obesity has significantly increased, and it is now considered an epidemic. Obesity constitutes a severe public health problem, as it substantially increases the risk of chronic diseases such as type 2 diabetes, cardiovascular disease, blood pressure, and certain cancers. This has raised the awareness level among the population regarding severe chronic disease, which can be avoided by following appropriate action plans, including the following:

• In March 2023, the World Obesity Federation started a new campaign on obesity under the name “Changing Perspectives: Let’s Talk About Obesity” on the occasion of World Obesity Day with an aim to correct misconceptions with constructive communication and pave the way toward a healthier future.

Such initiatives made by international organizations and strict implementation will increase awareness regarding disease conditions. Several industry players developing and engaged in launches of effective therapeutics are strategically endorsing their products to tackle the problem, propelling the growth of the anti-obesity drugs market during the forecast period.

• In June 2023, Retatrutide, an investigational drug of Eli Lilly Company with the potential to treat obesity and type 2 diabetes and is suitable for once in a week injection. These diabetes drugs work by appetite suppression to induce weight loss.

Anti-obesity Drugs Market Growth Factors

Increasing Prevalence of Obesity to Boost the Expansion of the Market

The prevalence of obesity has radically increased in all regions of the world, but the rate varies significantly by country due to sedentary lifestyle trends and unhealthy diets. Even though there is no direct correlation between obesity rate and the economic status of a country, it has been observed that wealthier countries tend to implement more programs, campaigns, and initiatives to raise awareness and education among people about healthy lifestyles.

• In March 2023, the World Obesity Federation published an article stating that 4.0 billion people globally are anticipated to live with obesity by 2035 if measures are not taken in current stage.

In terms of the impact on society as a whole, it has significant direct and indirect cost implications, which place considerable strain on healthcare and social resources. Some European countries most affected by this “obesity epidemic” include Malta, Hungary, and Lithuania.

• According to the World Obesity Atlas 2023, published by World Obesity Federation in March 2023, obesity and overweight will have economic impact globally and the number is going to surpass USD 4.32 trillion annually by 2035.

Additionally, in Asian countries the prevalence of obesity is expected to grow at a substantially higher rate. It is estimated that India and Pakistan will have highest prevalence of obesity among adults by 2035.

Increasing Pipeline Drugs for Obesity by Market Players to Propel the Growth of the Market during the Forecast Period

Globally, obesity has reached epidemic proportions, and as per WHO data, at least 2.8 million people are dying each year due to this problem. This increase in the prevalence of obesity will significantly increase the demand for effective therapeutic measures to combat the disease. As the problem of obesity is anticipated to grow over the next few decades, the need for the launch of new anti-obesity drugs in the global market will be greater. This has led several prominent and emerging companies to be engaged in R&D initiatives for the development of anti-obesity drugs to fulfill the demand.

• In May 2023, Innovent Biologics, Inc.’s phase 2 clinical study of mazdutide (IBI362) with a higher dose of 9 mg achieved positive outcomes in Chinese adults with obesity. Such developments in R&D reflect a great potential for future product launches.

RESTRAINING FACTORS

Stringent Drug Approval Policies May Limit the Market Growth Prospects

Despite the increased need for effective anti-obesity drugs, the stringent regulatory scenario is one of the substantial hindrances to market growth. There is considerable difficulty in the regulatory process for the approval of new anti-obesity drugs, which may prevent many established biopharmaceutical companies from investing in this market. Moreover, it also increases their R&D expenses and limits revenue growth, impacting the scope for new product launches and restraining market growth.

• The European Medicines Agency (EMA) has issued regulatory approvals for only three drug therapies (orlistat, bupropion/naltrexone, and liraglutide) in contrast to the U.S. FDA’s approval of five drug therapies. For instance, many regulatory bodies utilize a guideline of 5.0% total weight loss to determine whether a drug induces a significant weight loss. Such stringent regulatory requirements significantly hamper the global anti-obesity drugs market growth.
