A recent study suggests 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 stop conventional diet and exercise plans.
Findings released in a major medical journal shows that while obese people can lose substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month after stopping.
"Individuals purchasing these treatments need to be cognizant of the danger of rapid rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
Such speed of regain suggests a return to starting weight in about 18 months.
Analyzing Approaches
The study, which examined dozens of trials involving over 9,000 of participants, compared the effects of these new drugs with older methods.
Scientists point out that people who shed pounds through lifestyle changes alone typically have a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Rebound
Experts propose the way of the injections accounts for the heightened rebound.
The injections copy a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication means hunger is uncontrolled, making overeating far more likely."
A Chronic Condition?
Health authorities suggest the jabs for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, considering the high risk of relapse, the treatment should be considered long-term.
This opinion is echoed by pharmaceutical companies, who state that the results "emphasize the chronic nature of excess weight," akin to managing conditions like hypertension.
Patient Accounts
Individuals who have stopped the medication describe a intense return of hunger.
"I experienced a switch activating and I was suddenly extremely hungry," said an individual.
The struggle is exacerbated if users have not established lasting lifestyle or habit changes during therapy.
Growing Use
Recent estimates show that a significant number of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while the jabs are potent agents for shedding pounds, they are not a standalone cure and lasting health benefits hinges on integrated lifestyle management.
