Fresh analysis indicates that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who end conventional lifestyle plans.
Research printed in a major medical journal demonstrates that while overweight people can lose substantial amounts of their total mass while using the jabs, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these drugs must be aware of the risk of quick weight regain when the therapy is stopped," stated expert Dr. Susan Jebb.
That rate of regain suggests a return to starting weight within about one and a half years.
Comparing Approaches
The research, which examined 37 of trials involving over 9,000 of participants, contrasted the results of the injectable medications with conventional dieting.
Scientists point out that people who shed pounds through lifestyle changes alone generally experience a slower creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Experts suggest the mechanism of the injections accounts for the heightened regain.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement results in appetite is no longer kept in check, making overeating far more likely."
A Lifelong Disease?
The NHS suggest the jabs for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the high risk of relapse, the treatment might need to be ongoing.
This opinion is supported by pharmaceutical companies, who state that the results "emphasize the long-term character of excess weight," similar to managing diseases like hypertension.
User Accounts
People who have discontinued the jabs report a powerful resurgence of appetite.
"It was like a trigger flipping and you're instantly extremely hungry," described a patient.
The struggle is compounded if users have not adopted sustainable lifestyle or habit modifications during treatment.
Widespread Use
Figures suggest that millions of adults in the UK have used these injections in the past year, with demand continuing to grow.
- Adoption is greater among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, experts caution that while these medications are powerful agents for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on combined lifestyle changes.
