Fresh analysis reveals that patients who come off popular slimming jabs like Mounjaro or Wegovy may regain lost weight much more quickly than those who end conventional lifestyle regimens.
Research printed in a prominent medical journal points out that while obese individuals 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 upon discontinuation.
"Individuals using such treatments should be informed of the risk of rapid rebound weight gain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of regain means a reversion to starting weight within about a year and a half.
Analyzing Approaches
The research, which examined dozens of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.
Researchers emphasize that people who shed pounds through diet and exercise typically see a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Regain
Doctors propose the mechanism of the drugs is key to understanding the accelerated weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the body to produce less of its own natural hormone, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in hunger is uncontrolled, making excessive eating far more likely."
A Lifelong Issue?
Health authorities recommend the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, due to the significant potential of relapse, the treatment is often long-term.
This view is supported by pharmaceutical companies, who state that the findings "emphasize the long-term nature of obesity," comparing it to managing diseases like high blood pressure.
Patient Accounts
People who have stopped the jabs describe a intense resurgence of hunger.
"It was like a trigger activating and you become ravenous," recalled one woman.
This difficulty is worsened if users have not developed lasting dietary or behavioural changes during therapy.
Growing Interest
Figures suggest that millions of people in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is higher among females than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
In conclusion, experts emphasize that while these medications are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss relies on combined lifestyle changes.
