Will I be able to maintain my weight even after stopping the weight loss injections?

I have tried controlling my diet several times to manage my weight, and while I do well at first, I always end up reverting to my old habits over time. This time, I want to manage it more systematically, so I am looking into weight management methods offered at hospitals.

Then I learned about weight loss injections, and I think management after stopping is just as important as using them. I am wondering if there is a possibility of my appetite returning or my weight increasing once I stop using the injections. I know it varies from person to person, but I would also like to know what criteria are used to determine when to stop.

Would it be helpful to change my diet and exercise habits while using the medication? I am also wondering if it is better to develop a treatment plan with medical professionals before discontinuing the weight loss injections, rather than stopping abruptly. Please let me know if I can receive guidance on not only the duration of use but also a plan for maintaining my weight afterward during the initial consultation.
