"No, no, no, you don't need to change a thing. Keep shoving your face with greasy, subsidized corn-oil fried fast food. Just take this hormone-disrupting injection (only 48 easy payments of $126.89/month (plus interest)) and you'll never get unproductiv- um, I mean, fat!"
It's actually even worse than that. It's once a month for the rest of your life, because studies have shown that you gain the weight back when you stop taking it.
Oof, screw that. If I wanted to lose weight I'd do it the old-fashioned way.
That being said, there are diseases like Down Syndrome where this is better than the alternative; they're genetically predisposed to overly harsh weight gain and can't lose it naturally.
Jesus, I wasn't thinking about that until you pointed it out but you're right. If I wasn't such a memory-hoarding dorkbrain I wouldn't have even realized why you're right without knowing what it's called to google it.
Yes, I don't know what it's called, but if you ever have to give someone allergy/heart attack/diabetes medication by injection, make sure the damn syringe is empty (pushed down entirely) until after the tip is submerged in the medicine because air bubbles in your blood will cause your heart to stop or something. It's really that important, and this is why doctors get paid the big bucks.
One of the few medical things you see on TV that's a good idea, that pointing the needle upward and squeezing until a bit of fluid has spurted out, to make sure and get the air bubbles out.
Yeah the doctors get paid the big bucks for that, meanwhile your friendly neighbourhood junkie has done 126,234 injections both on themselves and others, without ever putting in a bubble, and they get jack shit. How is that fair?
As far as I know yes, it works by reducing appetite. So there definitely is the risk of just bouncing back after one stops using it, assuming nothing else has changed.
That said, this doesn't necessarily make it worthless. When treating something like depression one might also prescribe something that improves the mood to support psychotherapy to treat the underlying causes. In a similar way losing weight first through medication and then having therapy alongside it or starting to do sports (that gets easier to pick up with lower weight) might improve treatment outcomes.
And theoretically if it were cheap enough and without longterm side effects, then I could see a scenario where taking it permanently could still be better than the detrimental health effects obesity has.
