A new generation of obesity drugs has emerged, offering hope for those struggling with weight loss. These drugs have shown impressive results in terms of shedding excess pounds. However, many patients are left wondering what happens once they stop treatment. Will the weight come back? A recent study published in the Journal of the American Medical Association sheds light on this question and highlights the potential challenges faced by patients who rely on these drugs for long-term weight loss.
The study focused on the effects of tirzepatide, a compound found in Eli Lilly’s weight loss drug called Zepbound. After 36 weeks, 670 adults achieved a significant average weight loss of 20.9 percent while using the drug. The participants were then divided into two groups: one continued taking Zepbound, while the other group received a placebo. After 88 weeks, those who had been on the placebo regained nearly half of the weight they had lost, ending up 9.9 percent lower than their baseline. In contrast, the group on Zepbound continued to lose weight, with a final weight 25.3 percent lower than their starting point.
These findings suggest that patients may need to rely on ongoing treatment with obesity drugs to prevent weight regain. The study’s authors emphasize the importance of pharmacotherapy in maintaining weight reduction. They point out that previous trials with other similar medications, such as semaglutide, have also shown substantial weight regain after stopping treatment. Semaglutide is the active ingredient in Novo Nordisk’s Ozempic and Wegovy, which, like Zepbound, belong to the class of drugs called GLP-1 agonists. These drugs mimic the function of a hormone that secretes insulin, slows down stomach emptying, and suppresses appetite.
Jeff Emmick, a spokesperson for Eli Lilly, emphasizes that obesity should be treated as a chronic disease that often requires ongoing pharmacotherapy. Once weight goals are met, treatment should not be discontinued abruptly. Instead, a maintenance plan should be put in place to prevent weight regain. This highlights the need for patients, healthcare providers, and the general public to better understand the nature of obesity as a chronic condition.
While GLP-1 agonists have shown promise in reducing the risk of cardiovascular disease associated with obesity, they also come with potential risks and side effects. Gastrointestinal issues are commonly reported, including nausea, diarrhea, constipation, and vomiting. Although serious complications are rare, there is concern among experts about the long-term use of these medications. The cost of obesity drugs can also act as a deterrent, as they are often not covered by insurance plans, including Medicare, which is barred from covering them.
The study’s findings highlight the complex nature of obesity and the challenges that accompany long-term weight loss. Obesity drugs offer a promising tool in the battle against this chronic condition, but they are not a magic bullet. Patients need to be aware of the potential for weight regain and the importance of continued treatment to maintain long-term success. Further research is still needed to better understand the mechanisms behind weight regain after discontinuing drug therapy and to develop comprehensive treatment approaches that address the complexities of obesity.
The newfound optimism surrounding obesity drugs must be tempered with the recognition of the challenges that lie ahead. While they can be effective in achieving significant weight loss, their limitations become apparent when treatment is stopped. Developing a more nuanced understanding of obesity as a chronic disease and the importance of long-term treatment is essential for both patients and healthcare providers. By embracing this perspective, individuals can approach weight loss with a more realistic and sustainable mindset, paving the way for more effective strategies in the fight against obesity.
