The year 2023 saw several developments that have transformed the treatment of obesity, bringing new hope but also new challenges. Powerful new weight loss drugs like semaglutide (Wegovy) and tirzepatide (Mounjaro) have shown remarkable effectiveness for weight loss and treating obesity-related conditions like diabetes. However, concerns remain about long-term safety, high costs, and equitable access.
New drugs usher in an “obesity treatment revolution”
In 2023, new glucoincretin drugs dubbed “Obesity Treatment Revolution” drugs transformed treatment for obesity and weight loss. As reported by The Guardian and other outlets, drugs like semaglutide and tirzepatide produce significant weight loss, reducing BMI by over 10 points on average. This surpasses previous drug treatments and even weight loss surgery in effectiveness.
In addition to direct weight loss impacts, these drugs show promise for treating obesity-linked conditions like diabetes and heart disease. This has generated intense interest and heavy investment from major pharmaceutical companies.
Usage and costs drive access concerns
However, these revolutionary medications also come with drawbacks. As Stat News reports, key questions remain around long-term safety given the drugs’ impacts on glucose, heart rate, thyroid, and other systems. The FDA only approved semaglutide for chronic weight management in 2021, so there is still much to be learned about effects over years of use.
In addition, the high costs of these medications raises concerns around access and inequality. As Bloomberg notes, semaglutide retails for over $1,500 per month without insurance. While strong sales buoyed stock prices for manufacturers like Novo Nordisk in 2023, a growing usage boom could strain insurers and widen treatment gaps.
What comes next?
In 2024 and beyond, use of glucoincretin drugs for weight loss and diabetes is expected to continue growing rapidly. Some projections estimate the global obesity treatment market may reach $122 billion by 2028, more than double current levels. Further innovation in drug formulations and delivery mechanisms is also anticipated, with a nasal semaglutide spray possibly arriving in 2024.
However, concerns around costs, access, and equitable treatment will likely come to the forefront. As a USA Today roundup notes, lengthy insurance approval processes for obesity drugs already disadvantage vulnerable groups, while profit-seeking and off-label usage add to cost burdens.
Tackling such issues while responsibly leveraging these groundbreaking medications will be a key challenge in realizing their promise. Going forward, policymakers, researchers and clinicians will need to work closely with insurers and manufacturers to ensure safety, effectiveness and access. If successful, millions stand to benefit from meaningful weight loss, reduced diabetes burden, and years of healthy life gained.
