No you are not lazy, you are just having serious thoughts about the effects long term your weight will have on your health and that maybe you need help.
Its true that most hospitals follow the NICE guidelines of BMI of 35 and over with comorbidities and 40+ without. Some have much stricter rules which makes it at times a real postcode lottery.
I had my band with a BMI of 35 but at the time my hospital required a BMI of 50+ to qualify for NHS surgery - with no comorbidities. So going private was my only choice.
Things had changed when I was referred a few years back and with a BMI of 33 on the day of surgery and this time with comorbidities, I qualified for surgery.
The only certain thing is that you will either lose weight by yourself or you won't manage to and put even more on.
I think its a really good idea to get the support of your GP in the first instance.
In the meantime, please read some of the band and pilication diaries and threads on here to get a feel for what life would be like post op but please be aware, I don't think we have any recent pilication patients who are regular posters xx
