This comment is not about the specifics of OP’s case, but about the question of why there are rules about who can be prescribed WLI’s. Those rules are: BMI 30+, or 27+ with one of several health conditions.
The reason there is a limit is that these drugs have risks and side effects, as do all medications. When someone is above a certain size, the risks from their weight are higher than the risks from the medication, therefore overall they are better off using them and losing weight versus not using them and staying the weight they are. At the population level, though - if you are one of the users who had a serious and irreversible complication from using them, you might wish you hadn’t.
for people who are normal weight or only slightly overweight, the health benefits they could get from the weight loss are quite small, and not worth the risk of the side effects. That’s the basis for the limitations as to who can be prescribed them.
People who have lost weight on them and are below the weight at which they would be eligible are a different case. The assumption there is that if they stopped the drug they would regain the weight and their weight-related risks would go up again.
Someone who wants to from a BMI if 30 to 25 is not in the same situation as someone who wants to go from 25 to 30, even though they both want to lose the same amount of weight. The first would be getting a much greater benefit to their health, but they both face the same risk from the jabs.
And someone who is at a BMI. of 25 having used the jabs to get there is not in the same position as someone starting out at 25.
