Maybe I can provide a slightly different perspective.
Given that I've had both WLS and saxenda- was waiting on wegovy to come out (same medication just different dosages)
The semaglutide/wegovy..any of those jabs I think are a better idea than WLS, atleast as a first option.
My experience- weight didn't drop off massively quickly, but it was coming off. The real difference to me was that I was experiencing freedom from food.
The freedom I had experienced meant I could make healthier choices, not based on craving and it was like the slot machine that would usually go off in my brain as I ate wasn't on any more. Food became a chore to eat, so past a few mouth fulls I didn't really want to continue eating. Food didn't control my life for that time.
When I stopped, I felt hungry as a bear, but my stomach had shrunk which was great. I could eat even less.
Things I would be aware of- because it slows gastric emptying, it can slow how you absorb some medications including the pill. Some women have fallen pregnant this way (myself included) So might be a good idea to double up on BC. I wasn't even ovulating, but I did in that 6 week period and my pill didn't work lol.
I wouldn't hesitate to try the jabs instead of WLS... you can time temporarily stop the jab if you have a meal you really want to enjoy, you can't turn off the surgery for an evening.
