I thought the same for myself & was told the same by people.
I was 192 lbs at 5'5" (size 10), but I had high blood pressure, high cholesterol and high triglycerides. I went to the appointment with the surgeon scared he'd deny me but he said he thought I'd be a good candidate because of my other health issues, then I was scared the insurance company would reject me... but my insurance approved my surgery and paid for it.
I will say my weight is coming off much slower than it does for people who have a higher weight to begin with.
But I am 170 lbs now and over 5 weeks post-op.
I say GO FOR IT. It is one of the best decisions I've made for myself (along with lasik surgery). I would have NEVER gotten off of sugar and carbs without the surgery. Now I do NOT want them or need them, especially sugar. 🤮
