A recent study suggests that patients who stop using blockbuster slimming jabs like Wegovy and Mounjaro may regain lost weight much more quickly than those who end conventional lifestyle plans.
Published data in a major health publication demonstrates that while overweight people often shed about a fifth of their body weight while using the jabs, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals buying these medications should be aware of the potential of rapid weight regain when the therapy ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight within about 18 months.
Analyzing Treatments
The analysis, which looked at dozens of trials involving over 9,000 of patients, contrasted the results of these new drugs with conventional dieting.
Scientists emphasize that people who lose weight through diet and exercise typically have a less rapid weight regain—around 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Doctors suggest the mechanism of the injections is key to understanding the accelerated weight return.
The injections copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' leads to appetite is uncontrolled, making binge eating a significant risk."
A Chronic Issue?
The NHS advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians say that, due to the significant potential of relapse, the treatment might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who say that the findings "highlight the persistent nature of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
Users who have discontinued the jabs explain a intense return of cravings.
"It felt as if a switch activating and I was suddenly starving," said an individual.
This difficulty is exacerbated if individuals have not adopted permanent dietary or behavioural modifications during therapy.
Widespread Adoption
Recent estimates show that a significant number of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is higher among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are potent tools for weight loss, they are not a permanent cure and long-term success hinges on integrated behavioural support.
