The surging demand for anti-obesity drugs

June 17, 2024

Summary: There’s been a 42.3% increase in the number of people being treated with anti-obesity drugs.1 Medications used to treat obesity can benefit the health and well-being of employees, which can have positive carryover to the workplace. This article explores proactive measures that employers can take to help their employees on their journeys to healthier lifestyles, created in collaboration with our Medical Director, Cleveland Clinic Canada.

Ozempic® is not included in this analysis of anti-obesity medication. Health Canada has approved Ozempic® for the treatment of Type 2 diabetes and not for the treatment of obesity.

Unique claimants for anti-obesity drugs up 42.3% 1

Anti-obesity drugs are prescribed by doctors to help some individuals manage their weight and improve their overall health and well-being.2 These medications can be helpful to address weight and underlying weight-related conditions or symptoms such as Type 2 diabetes, high blood pressure, osteoarthritis, and more.3

The use of anti-obesity drugs has grown substantially. Our aggregate drug claims data shows a 42.3% increase year-over-year in the number of people being treated with these drugs in 2023.1 This indicates a rising trend in individuals seeking help for weight loss, but also increased interest among health care providers in prescribing these medications due to growing evidence supporting their use.4

The increased media coverage on Ozempic® may also be contributing to the growing interest in these medications.5 It's important to emphasize that Ozempic® isn’t currently approved as an anti-obesity treatment in Canada.6 However, other related compounds will likely be approved and available soon.

More women are using anti-obesity drugs than men

Our aggregate claims data also reveals more women are using these types of drugs than men. The majority of claimants, 78.8%, are women, whereas men make up 21.2% of the total.1

While these medications are intended to address weight as well as related health conditions, the higher use amongst women could be related to social pressures and body image concerns that are sometimes experienced by women. The Canadian Women's Foundation points to popular media and social media as contributing factors to these issues.7 For this reason, many women face ongoing expectations to conform to certain physical standards, which may lead to a greater interest in weight management approaches, including these newer medications.8

What medications are used to treat obesity?

There are four medications approved by Health Canada to treat obesity.2 These include liraglutide (Saxenda®), naltrexone/bupropion (Contrave®), orlistat (Xenical®), and semaglutide (Wegovy®).2

The following chart shows the different types of drugs that may be prescribed for obesity and the weight-loss results they have achieved in studies. It is important to note that each individual will respond differently to these medications, with some having more or less weight loss.

Anti-obesity drugs and lifestyle factors

These medications are generally prescribed alongside other lifestyle changes that can support weight management, such as nutrition and physical activity.2 This reflects the increasing recognition of obesity as a chronic condition that is best addressed through a combination of interventions.

Importantly, The Wellness Report 2023 data shows that 45% of people are not getting enough physical activity, while 32% are not getting enough sleep.10 It also reveals that 73% of individuals are not consuming the recommended five or more portions of fruits and vegetables per day, indicating a significant gap in nutrition.10

Adjusting lifestyle factors can optimize the impacts of anti-obesity medication and provide the additional support needed to help an individual manage their weight.2

Workplace benefits of providing coverage for anti-obesity medication

Anti-obesity medications can’t help your employees with weight management unless they can access them. Including coverage for anti-obesity drugs in your group benefits plans is a crucial step as it lowers barriers to access and can show your commitment to supporting your employees’ overall health and well-being.

“The workplace benefits of providing coverage for anti-obesity medication are becoming increasingly evident as more people strive to manage their weight and improve their overall health,” says Dr. Steve Pomedli of Cleveland Clinic Canada. “These medications can have significant positive impacts on employees in their obesity management journeys and can also have positive impacts for employers.”

Supporting the health and well-being of your employees isn’t just the right thing to do, it can be good for business too.11 By effectively managing weight, individuals may experience an improvement in obesity-related health conditions such as diabetes, heart disease, high blood pressure, and reductions in day-to-day symptoms as well.12 This, in turn, can lead to fewer sick days, lower healthcare costs, and increased overall productivity in the workplace.11

According to The Wellness Report, 32% of employees surveyed are at risk of developing a chronic condition based on their body composition (the makeup of a person's body).10 This statistic highlights the importance of being proactive and by supporting your employees by providing them with coverage for anti-obesity medications.

Rising demand and the implications for employers

The increasing use of anti-obesity medications suggests there could be an underlying unmet need for support and treatments that can help individuals with weight management, and in addressing medical conditions related to their weight.

Taking additional proactive measures, like offering workplace wellness programs and providing resources to support employees, such as access to nutrition counselling, fitness programs, and weight management support, are also important. Psychological supports can also help with behavioural change for better weight management, therefore offering coverage for these services can help employees access the services they may benefit from.

Doing so may help set your employees up for success in achieving and maintaining a healthy weight, reducing the risk of weight-related health issues, and promoting overall well-being.
