It is not a silver bullet. One thing to look out for is muscle atrophy. It is important to maintain (or, from the description you provided, start) regular exercise.

Source: my dad and one of my partners are on GLP-1s - my dad for weight (and I have had multiple frustrating conversations with him trying to convince him to be less sedentary), my partner for other medical reasons (it’s useful for a lot of stuff besides obesity; she still occasionally struggles to maintain muscle mass, despite regular exercise).

As others have said, a doctor should be consulted. And try to do some digging yourself beforehand, because it seems that many doctors these days are glossing over the side effects, largely due to how wildly popular and “magical” the general populace perceives it as.
