GLP-1 medications, such as Ozempic and Wegovy, suppress appetite and aid weight loss for eligible NHS patients. However, they are not a permanent cure for obesity.
Dr. Karan Rajan's Key Insights
In a popular TikTok video, Dr. Karan Rajan (known as Dr. Raj online) addresses a common question: "Do you have to take a GLP-1 forever?"
He describes obesity as a chronic relapsing condition, cautioning against short-term use without comprehensive weight management.
"An uncomfortable truth: GLP-1s aren't cures. They act like blood pressure pills or statins—if you stop, you lose the effect."
Lifestyle Changes Are Essential
To sustain long-term health benefits beyond medication adherence, Dr. Rajan emphasizes non-negotiable lifestyle adjustments.

All weight management medications must pair with a reduced-calorie diet and increased physical activity.
