A recent study indicates that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who stop traditional diet and exercise regimens.
Research printed in a major medical journal points out that while overweight people often shed a large proportion of their body weight while on the medication, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing these medications should be aware of the danger of rapid rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to starting weight within about one and a half years.
Comparing Therapies
The analysis, which reviewed dozens of trials involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone generally experience a more gradual weight regain—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Regain
Doctors propose the mechanism of the injections is key to understanding the heightened rebound.
These medications copy a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication results in appetite is no longer kept in check, making overeating much more probable."
A Lifelong Disease?
The NHS recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals argue that, given the high risk of relapse, the treatment is often life-long.
This opinion is reinforced by drug manufacturers, who say that the findings "emphasize the long-term character of obesity," similar to managing diseases like hypertension.
User Accounts
People who have discontinued the medication explain a powerful resurgence of hunger.
"I experienced a switch activating and you're instantly ravenous," said an individual.
This difficulty is compounded if patients have not established lasting dietary or behavioural modifications during treatment.
Widespread Adoption
Survey data show that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is more common among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
Ultimately, researchers stress that while these medications are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits likely depends on ongoing lifestyle changes.
