Glucagon-like peptide-1 receptor agonists (GLP-1 agonists) are a class of medications primarily used to manage type 2 diabetes (T2D) by enhancing insulin secretion and lowering blood glucose levels. Recently, these drugs have also gained attention for their side effect of weight loss, leading to a surge in their use for obesity management. This trend has resulted in significant shortages, impacting patients who need these medications for diabetes management.
Rise in Non-Diabetic Use of GLP-1 Agonists
Recent research highlights a sharp increase in the use of GLP-1 agonists among individuals without type 2 diabetes. According to a study published in the Annals of Internal Medicine, the number of new users of GLP-1 medications without diabetes has doubled between 2011 and 2023. This includes people with a body mass index (BMI) of 30 kg/m² or greater and those with a BMI of 27 to 30 kg/m² who have obesity-related comorbid conditions.
While GLP-1 medications like Wegovy and Zepbound have FDA approval for weight loss in individuals with obesity, many others are using drugs such as Ozempic off-label for similar purposes. This off-label use has contributed to the increasing demand for GLP-1 agonists, exacerbating shortages.
Impact on Diabetes Drug Supply
The increased demand for GLP-1 drugs for weight loss has led to significant shortages, making it challenging for individuals with type 2 diabetes to access their necessary medications. The shortage is further compounded by disparities in insurance coverage, which affects access to these drugs based on socioeconomic and racial factors.
Dr. David Cutler, a family medicine physician, and Dr. Mir Ali, a bariatric surgeon, both emphasize that the growing use of GLP-1 medications for non-diabetic purposes has worsened the availability of these drugs for diabetes management. High costs and limited insurance coverage exacerbate the problem, leaving many patients struggling to obtain their prescribed medications.
Study Findings and Implications
The study found that the proportion of GLP-1 medication users without FDA-approved indications increased from 0.21% in 2019 to 0.37% in 2023. This shift reflects a broader acceptance of these medications for treating obesity and related conditions, signaling a significant public health trend.
The research also revealed that the largest users of semaglutide, a popular GLP-1 agonist, are disproportionately female and non-Hispanic white. This demographic disparity highlights existing health access issues, as insurance coverage and cost barriers can exacerbate inequalities in treatment access.
Addressing the Shortage
Addressing the GLP-1 medication shortage requires multifaceted solutions:
Increasing Production: Drug manufacturers need to ramp up production to meet the growing demand. However, this may be limited by production capacity and regulatory constraints.
Insurance Coverage: Expanding insurance coverage for both diabetic and non-diabetic uses of GLP-1 medications could alleviate some access issues. This involves negotiating with insurance providers to ensure broader coverage and affordability.
Research and Alternatives: Ongoing research into the broader impacts of GLP-1 medications, such as their effects on metabolic diseases like metabolic-associated steatohepatitis (MASH), could potentially expand indications and provide alternative solutions. Additionally, exploring non-FDA approved options might offer temporary relief, though they come with risks.
Conclusion
The rising use of GLP-1 agonists for weight loss has led to significant shortages, impacting individuals with type 2 diabetes who rely on these medications for blood glucose management. To mitigate these shortages and improve access, a combination of increased production, better insurance coverage, and ongoing research into alternative treatments will be essential. Addressing these challenges is crucial to ensure equitable access to GLP-1 medications for all who need them.
