It's not really different than losing weight by any other method in that respect.
There is always the risk of regaining weight unless you continue to do whatever caused you to lose weight (e.g. restricting calories) to some extent.
I guess a "cure" would be good but since we don't have one having to periodically go back on glp drugs if you gain weight is no different from periodically having to go on a diet if you gain weight.
On the other hand most people tend to naturally gain weight pretty slowly (e.g. a pound a year) so having to go on glp drugs for a period every few years wouldn't even be that bad, especially if they're available in pill form.
