Market Scope

Segment Insights

Drug Type Insights

What made semaglutide the dominant segment in the obesity GLP-1 market?

The semaglutide segment dominated the market with a major share of 46% in 2025 because of its robust clinical efficacy in glycemic control and weight loss, which is backed by a wealth of empirical data. Strong physician confidence, widespread regulatory approvals, and high patient adoption all helped to establish its leadership. Stable demand was also bolstered by well-known branded goods and robust reimbursement coverage in several nations. The segment's leading position is further reinforced by the availability of long-acting formulations.

The Tirzepatide segment is expected to grow at the fastest CAGR in the coming years, driven by a dual GIP and GLP-1 receptor mechanism providing better results for weight loss. Adoption of Tirzepatide is being accelerated by strong clinical trial results showing improved efficacy over conventional GLP-1 therapies. Further bolstering rapid growth are expanding label indications and raising physician awareness.

Route of Administration Insights

Why did the parenteral segment dominate the obesity GLP-1 market?

The parenteral segment dominated the market while holding the largest share of 88% in 2025 because injectable formulations provide precise dosing, rapid absorption, and sustained therapeutic effects, which are critical for achieving effective weight loss and glycemic control. These formulations are particularly preferred for chronic management of obesity, as they ensure higher bioavailability compared to oral alternatives and allow the use of long-acting, once-weekly or once-daily therapies. Additionally, parenteral GLP-1 treatments have strong clinical validation, which increases physician confidence and patient adherence, further driving market dominance.

The oral segment is expected to grow at the fastest CAGR in the coming years because of the increasing demand for convenient, needle-free treatment options that improve patient adherence and comfort. Oral formulations make long-term therapy more appealing, especially for patients hesitant about injections, and they allow broader adoption in outpatient and home-care settings. Additionally, advancements in drug delivery technologies are enhancing the bioavailability and efficacy of oral GLP-1 therapies, further fueling their market growth.

Target Indication Insights

Why did the type 2 diabetes segment dominate the obesity GLP-1 market?

The type 2 diabetes segment dominated the market with a 55% share in 2025 because GLP-1 therapies have been used for glycemic control for a long time, and diabetes is very common worldwide. Widespread adoption was aided by the dual advantages of blood sugar regulation and weight loss. Market leadership was strengthened by strict reimbursement regulations and the incorporation of clinical guidelines. Another important factor reinforcing the segment's dominance is doctors' confidence in GLP-1 treatments for the treatment of diabetes.

The obesity/chronic weight management segment is expected to grow at the fastest CAGR during the forecast period, fueled by growing awareness of obesity as a chronic illness and rising obesity rates worldwide. Adoption of obesity GLP-1 is increasing because of the expansion of regulatory approvals for weight management. Key growth drivers are raising patient awareness and the need for efficient non-surgical treatments. Better long-term results from weight loss are also speeding up the segment's growth.

Distribution Channel Insights

What made retail pharmacies the leading segment in the obesity GLP-1 market?

The retail pharmacies segment led the market with a 60% share in 2025 because they offer wide accessibility and convenience for patients seeking prescriptions and ongoing therapy refills. These pharmacies benefit from strong distribution networks, trusted brand presence, and immediate product availability, making them the preferred choice for both new and returning patients. Additionally, retail pharmacies often provide counseling support, insurance processing, and promotional discounts, which further drive adoption and sustained use of GLP-1 therapies.

The online/direct-to-consumer (DTC) segment is expected to grow at the fastest CAGR in the coming years due to the increasing preference for home delivery and digital access to medications, which offers convenience and privacy for patients managing chronic obesity. Growth is also driven by the rise of telehealth consultations and digital prescriptions, enabling easier patient access to GLP-1 therapies without visiting physical stores. Additionally, online platforms often provide competitive pricing, subscription refills, and reminders for adherence, which are boosting patient convenience and accelerating market expansion.
