The market for obesity and diabetes treatments, particularly GLP-1 drugs, is at a pivotal juncture with rising demand fueled by the growing prevalence of these conditions. Eli Lilly and Novo Nordisk dominate the industry, yet competition is intensifying as new entrants emerge, alongside more accessible treatment options and evolving insurance landscapes. However, access remains a significant hurdle, complicated by high prices and varying coverage, which calls into question the sustainability of this burgeoning market.

Overview of the Current Market Landscape
The appetite for blockbuster weight-loss and diabetes drugs continues to grow, with major pharmaceutical companies racing to capture market share. Eli Lilly and Novo Nordisk stand at the forefront of this competitive landscape, driven by soaring patient demand and a projected market potential of approximately $100 billion by the end of the decade. Analysts estimate that between 25 million to 50 million U.S. patients could benefit from GLP-1 medications by the year 2030, signaling ample opportunity for both established and emerging players in the sector.
Despite the optimistic outlook, significant challenges persist. The high cost of GLP-1 drugs, which can approach $1,000 per month without insurance, poses substantial barriers to access. Additionally, the insurance coverage landscape remains uneven; many insurers, including Medicare, do not provide coverage for obesity treatment, forcing a significant portion of the patient population to weigh whether to pursue these therapies. These multifaceted challenges will shape the trajectory of the weight-loss drug market moving forward.
Eli Lilly’s Market Position
Eli Lilly has made notable strides in the GLP-1 market, recently surpassing Novo Nordisk in terms of market share. As of August, Eli Lilly controlled approximately 57% of the U.S. market for injectable obesity and diabetes drugs, a significant leap from previous estimates. Analysts attribute this success to the superior safety and efficacy of Eli Lilly’s products, particularly its diabetes drug Mounjaro and the weight-loss treatment Zepbound. These advancements not only showcase Eli Lilly’s commitment to clinical excellence but also illustrate a shift in physician and patient preferences toward its offerings.
The headwinds faced by Novo Nordisk, once the market leader, have further contributed to Eli Lilly’s acceleration. Supply chain issues, regulatory challenges, and rising competition from compounded alternatives have allowed Eli Lilly to seize a commanding lead. As a result, Novo Nordisk recently reported a substantial drop in its stock value and revised its profit forecasts downward—a situation compounded by the looming negotiation of drug prices for Medicare patients.
Competition from Compounded Versions
Compounded GLP-1 medications have emerged as significant competitors in the market, particularly during periods of shortage for branded drugs. These compounded alternatives, typically offered at a lower cost, have drawn many patients who struggle to access the original formulations. The practice of compounding allows pharmacies to custom-mix ingredients to create medications tailored to individual patient needs, providing essential options, especially when branded therapies are unavailable.
Novo Nordisk faces heightened vulnerability from these compounded alternatives and has taken measures to mitigate this competition. Both Eli Lilly and Novo Nordisk have ramped up manufacturing capacities in response to market demands, leading the FDA to declare an end to the shortages of their prominent products. However, both companies remain vigilant against compounding pharmacies that have persisted in producing and marketing cheaper, unauthorized versions, which could threaten the integrity of their brands and market positions.
The Insurance Coverage Dilemma
Coverage of GLP-1 medications by health insurance is uneven and presents a critical challenge to increasing patient access. Current policies often restrict coverage to diabetes treatment, while many insurers, including Medicare, provide no coverage for obesity management. A survey by the International Foundation of Employee Benefit Plans indicated a slight increase in coverage for weight-loss GLP-1s, rising from 34% in 2024 to 36% in 2025. Still, these rates demonstrate that considerable gaps remain in access for those who may benefit from these therapies.
Employers have expressed hesitation to expand coverage due to concerns about high costs and possible gastrointestinal side effects associated with continuous drug therapy. As the market evolves and GLP-1 drugs gain approvals for additional chronic conditions—like cardiovascular disease and fatty liver—there is potential for more comprehensive coverage. Moreover, expanding Medicare coverage could catalyze wider acceptance and adoption of weight-loss medications among private insurers as well.
The Future of Oral Obesity Medications
Looking ahead, the development of oral GLP-1 medications holds promise to further transform the obesity management landscape. Novo Nordisk has already introduced an oral GLP-1 treatment for diabetes and is testing a version specifically for weight loss. Eli Lilly is also developing an oral counterpart, orforglipron, which shows great potential to capture a significant share of the market.
Experts speculate that the introduction of effective oral options could profoundly impact drug accessibility, although questions remain regarding their effectiveness compared to injectable versions. Initial clinical trials suggest that these oral contenders might not match the appetite-suppressing effects of injections, and varying side effects could influence patient willingness to switch therapies. Cost considerations will also play a crucial role, particularly if oral medications are positioned as lower cost alternatives. Physicians and patients will need clarity on whether the convenience of a pill outweighs its potential drawbacks.

Summary
The evolving landscape of the obesity and diabetes treatment market reflects a convergence of factors including heightened competition, the need for better access, and innovations in drug formulations. With Eli Lilly capturing significant market share and new competitors emerging, the industry is at a critical junction. While future oral treatments could provide greater accessibility, challenges such as cost, insurance coverage, and competition from compounded alternatives must be effectively navigated to truly enhance patient outcomes and market potential.
Frequently Asked Questions
Question: What are GLP-1 medications?
GLP-1 medications are a class of drugs used primarily to treat obesity and type 2 diabetes by mimicking the GLP-1 hormone, which helps regulate appetite and insulin levels.
Question: Why is insurance coverage for GLP-1s inconsistent?
Insurance coverage for GLP-1s is inconsistent due to varying health plan policies and the fact that many insurers only cover these drugs for diabetes treatment rather than obesity management.
Question: How do compounded GLP-1 medications differ from branded versions?
Compounded GLP-1 medications are tailored versions mixed by pharmacies, often marketed at lower costs compared to branded drugs, although they may lack regulation and can vary in safety and effectiveness.
