Fresh analysis indicates that people who stop using new weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who stop traditional lifestyle plans.
Research printed in a leading medical journal points out that while obese people frequently drop substantial amounts of their body weight while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing such medications must be aware of the potential of rapid weight regain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment weight in about one and a half years.
Comparing Treatments
The study, which examined 37 of studies involving over 9,000 of patients, contrasted the effects of these new drugs with other pills.
Scientists point out that people who shed pounds through dieting usually have a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Doctors propose the way of the injections is key to understanding the amplified regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means appetite is uncontrolled, making overeating far more likely."
An Ongoing Disease?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, considering the significant potential of relapse, the treatment should be considered ongoing.
This opinion is supported by drug manufacturers, who say that the results "emphasize the chronic nature of obesity," akin to managing conditions like high blood pressure.
Patient Accounts
Individuals who have stopped the medication report a powerful return of hunger.
"I experienced a trigger activating and I was suddenly starving," said a patient.
This challenge is exacerbated if patients have not established sustainable dietary or behavioural changes during therapy.
Significant Use
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on combined lifestyle changes.
