- An actual-world research adopted people who began GLP-1 medicines and discontinued them inside 3 to 12 months to evaluate weight adjustments after stopping remedy.
- Earlier than stopping the medicines, individuals handled for weight problems misplaced about 8.4% of their physique weight, whereas these handled for sort 2 diabetes misplaced about 4.4% on common.
- One 12 months after discontinuation, common weight regain was small. Individuals within the weight problems group regained about 0.5%, whereas these within the diabetes group misplaced a further 1.3% on common, although particular person outcomes different.
- Many individuals continued different types of remedy after stopping GLP-1 medicine, which can assist clarify why massive weight regain was not generally noticed.
Two broadly prescribed examples embrace semaglutide and tirzepatide. Each have gained world consideration for his or her capacity to probably help substantial weight reduction. Nevertheless,
Thus, questions stay about what occurs when people cease taking these medicines. Some analysis
Nevertheless, a brand new research, revealed in Diabetes, Obesity and Metabolism, signifies that individuals might preserve a lot of their weight reduction after discontinuation, notably in the event that they transition to different therapies or life-style help.
Within the new retrospective cohort research, researchers from the Cleveland Clinic analyzed digital well being report knowledge from 7,938 adults with obese or weight problems who started injectable semaglutide or tirzepatide between 2021 and 2023.
Individuals within the research discontinued remedy inside 3 to 12 months, and researchers tracked their weight adjustments and subsequent therapies for one 12 months after stopping the medicine.
The research staff in contrast weight adjustments amongst members who had used the medicine for weight problems versus these taking them for sort 2 diabetes.
Earlier than discontinuing remedy, people treating weight problems misplaced a median of 8.4% of physique weight, whereas these treating sort 2 diabetes misplaced a median of 4.4% of physique weight.
After 1 12 months with out the medicine, these within the weight problems group regained a median of 0.5% of physique weight, and people within the diabetes group misplaced a further 1.3% of physique weight on common.
Nevertheless, particular person outcomes different. Within the weight problems group, 55% gained some weight, whereas 45% maintained or continued reducing weight. Within the diabetes group, 44% gained weight and 56% maintained or misplaced weight.
General, these outcomes counsel that many individuals might not expertise the big weight regain reported in some randomized scientific trials.
Lead research writer, Hamlet Gasoyan, DS, PhD, MPH, a researcher with Cleveland Clinic’s Middle for Worth-Based mostly Care Analysis, spoke to Medical Information At present, emphasizing the significance of those ends in a real-world setting:
“Randomized scientific trials documented that discontinuation of novel weight problems medicines usually leads sufferers to regain weight,” Gasoyan instructed us. “For instance, within the SURMOUNT-4 trial, tirzepatide ‘discontinuers’ have been randomized to a placebo, and so they have been unaware whether or not they have been receiving tirzepatide or not.”
“In real-world settings, the most typical causes for discontinuation are value or insurance-related points, and unintended effects, with the previous predominating,” he added.
“Because of this it is very important perceive what extra weight administration efforts sufferers pursue in real-world settings after discontinuing semaglutide or tirzepatide, and whether or not long-term weight adjustments after discontinuation observe the patterns reported in randomized scientific trials.”

In line with the researchers, a possible cause for the distinction could also be that individuals typically proceed their remedy journey in different methods. Inside a 12 months of stopping their unique medicine:
- 27% switched to a different weight problems medicine
- 20% restarted their unique drug
- 14% continued remedy by means of life-style interventions, similar to visits with dietitians or train specialists
- fewer than 1% underwent bariatric surgical procedure.
These remedy changes might present a proof for why weight regain appeared smaller than beforehand reported in scientific trials.
Gasoyan added that, “on this massive observational research of sufferers who discontinued semaglutide or tirzepatide, reinitiation of the unique medicine or receipt of different weight problems remedy was frequent, which can clarify why they regained much less weight than sufferers in randomized trials.”
Moreover, earlier analysis means that GLP-1 drug discontinuation typically happens for sensible causes somewhat than lack of effectiveness.
For instance, insurance coverage protection may additionally affect remedy patterns. Individuals utilizing the medicines for diabetes have been extra more likely to restart remedy than these taking them for weight problems. That is probably as a result of diabetes prescriptions are extra constantly lined by insurance coverage.
The outcomes of this research probably spotlight the significance of ongoing, individualized help for individuals managing weight problems and sort 2 diabetes.
Whereas
Gasoyan expressed hope that this would possibly assist promote conversations between clinicians and people:
“For sufferers who must cease their GLP-1 RA or twin receptor agonist medicine, there are a number of different weight problems therapies out there. They might wish to focus on the out there choices with their clinician.”
Future analysis might deal with evaluating the effectiveness of various therapies after GLP-1 discontinuation. This might present pointers to assist clinicians and people make knowledgeable choices about long-term weight administration.
Commenting on future analysis, Gasoyan instructed MNT that “future research ought to study the comparative effectiveness of therapies for weight problems in sufferers who discontinue their novel GLP-1 RA or twin receptor agonist medicine.”
“We’re already engaged on the subsequent research, the place we study the comparative effectiveness of different remedy choices for weight problems in sufferers who discontinue semaglutide or tirzepatide, to assist sufferers and their clinicians make knowledgeable choices. This could inform patient-clinician conversations about different choices,” he mentioned.
