Weight Loss Therapeutics Market Dynamics: Drivers & Restraints

Drivers:

The rising clinical trials by key companies are significantly driving the weight loss therapeutics market growth

The growing number of clinical trials conducted by leading pharmaceutical companies is a key driver accelerating the growth of the weight loss therapeutics market.  These trials are not only advancing the development of innovative therapies but also building clinical validation and market readiness. For instance, in September 2023, Viking Therapeutics initiated the Phase 2 VENTURE trial for VK2735, a subcutaneously administered dual GLP-1 and GIP receptor agonist aimed at treating obesity. The trial initially targeted 125 patients but expanded to 176 due to increased clinician and patient interest. 

Subsequently, in February 2024, Viking announced that the trial successfully met its primary and secondary endpoints, with patients receiving VK2735 showing statistically significant reductions in body weight compared to placebo. The treatment was also deemed safe and well-tolerated, with most adverse events classified as mild or moderate. 

These instances illustrate how robust and expanding clinical pipelines by key players are driving therapeutic innovation, reinforcing investor confidence, and increasing the likelihood of broader adoption and regulatory approvals in the weight loss therapeutics market.

Rising global obesity rates are significantly driving the weight loss therapeutics market growth

Rising global obesity rates are a primary driver of growth in the weight loss therapeutics market. As lifestyles become increasingly sedentary and diets more calorie-dense, obesity has reached significant proportions worldwide. In 2024, the NCD Risk Factor Collaboration (NCD-RisC) reported that over one billion people globally are now living with obesity, including around 880 million adults and 159 million children and adolescents aged 5 to 19. 

According to the World Obesity Federation’s analysis of this data, nearly 3 billion people worldwide are affected by either overweight or obesity. These findings highlight a significant global health shift: in most parts of the world today, the risk to health from being overweight or obese is now greater than the risk from being underweight. This surge is not limited to high-income countries—low- and middle-income regions are also experiencing sharp increases in obesity-related health issues such as type 2 diabetes, cardiovascular disease, and certain cancers. 

The growing burden of these comorbidities has created urgent demand for effective medical interventions beyond lifestyle modification. In response, both public health systems and private healthcare providers are increasingly prioritizing pharmacological treatments for obesity. As a result, the escalating prevalence of obesity continues to expand the patient base and fuel strong, sustained growth in the weight loss therapeutics market.

Restraint:

Side effects associated with the therapeutics are hampering the growth of the weight loss therapeutics market

The rising concern over side effects associated with weight-loss therapeutics, particularly GLP-1 and dual/triple agonist drugs, is threatening to slow market growth and alter their adoption trajectory. 

While gastrointestinal issues like nausea, vomiting, diarrhea, and constipation remain the most frequently reported adverse events, they have led to a 25–65% discontinuation rate within a year for drugs like Wegovy, Ozempic, and Zepbound.

More alarming are recent safety signals: the UK’s MHRA has logged over 560 suspected cases of pancreatitis, including ten deaths, linked to these medications, sparking regulatory investigations and media scrutiny.

Even rarer effects, such as gastroparesis, bowel obstructions, and potential eye and thyroid issues, are emerging in real-world observations and vigilance data. These side effects could restrict individuals from using these medications and thus hamper the market growth.

Opportunity:

Development of biosimilars & generics is expected to create a lucrative opportunity for the growth of the weight loss therapeutics market

The development of biosimilars and generics presents a strong opportunity for the weight loss therapeutics market by significantly improving affordability and access. As branded anti-obesity drugs, such as GLP-1 receptor agonists (e.g., semaglutide in Wegovy/Ozempic), remain expensive and often inaccessible for many populations, biosimilars and generics can help expand access to these therapies, particularly in low- and middle-income countries. 

This increased affordability is likely to boost patient volumes and drive overall market growth. Furthermore, the entry of cost-effective alternatives will create competitive pressure on innovators to differentiate through next-generation formulations, improved delivery methods, or combination therapies.

Weight Loss Therapeutics Market, Segment Analysis

The global weight loss therapeutics market is segmented based on therapeutics, condition, dosage form, distribution channel, and region.

The prescription drugs segment was valued at US$ 1.79 Billion in 2024 and is estimated to reach US$ XX Billion by 2033, growing at a CAGR of XX% in the weight loss therapeutics market 

The prescription drugs segment holds a dominant position in the global weight loss therapeutics market due to the superior efficacy, regulatory backing, and growing physician acceptance of pharmacological interventions for obesity management. 

Medications such as GLP-1 receptor agonists have demonstrated substantial and sustained weight loss outcomes in clinical trials, far surpassing results achievable through lifestyle changes alone. 

The U.S. FDA approvals of novel drugs like Zepbound (tirzepatide) and Wegovy (semaglutide) have further accelerated demand, especially among patients with obesity-related comorbidities such as type 2 diabetes, sleep apnea, and cardiovascular disease. In studies, Zepbound has led to a 21% weight loss in adults using the highest dose, while Wegovy has led to about a 15% weight loss.

Additionally, the surge in R&D investment, expanding treatment guidelines, and increasing awareness of obesity as a chronic medical condition have contributed to growing prescriptions. For instance, in June 2024, Novo Nordisk launches weight-loss drug Wegovy in India to compete with Lilly's Mounjaro.

With broadening payer coverage, improved long-term safety data, and the potential entry of oral formulations and multi-agonist therapies, the prescription drug segment is poised to maintain its leadership and expand its reach in both developed and emerging markets..
