Weight Regain After Stopping Weight Loss Medications
Doctors have new medicines like semaglutide and tirzepatide that help people lose a lot of weight.
But when people stop taking these medicines, they often gain the weight back.
A big study found that people regain about 0.4 kg per month on average, and even faster for the newer drugs.
It takes about 1.7 years to return to the original weight.
Along with weight gain, health improvements like better blood sugar and cholesterol levels also disappear.
To prevent this, doctors suggest long-term treatment, slowly reducing the dose, and focusing on diet and exercise.
It's important to remember that weight regain is not a personal failure but a natural response of the body.
Weight loss medications like semaglutide and tirzepatide help people lose significant weight but lead to weight regain when stopped.
A study found that people regain an average of 0.4 kg per month after stopping these medications, with newer drugs causing faster regain.
Body weight returns to baseline in about 1.7 years, and metabolic health deteriorates within 1-1.5 years.
Weight regain after stopping medications is faster than after stopping lifestyle programs, highlighting the importance of sustained behavioral changes.
Long-term treatment, dose tapering, and increased focus on diet and exercise are suggested to minimize weight regain.
