I suppose it's a good idea that somebody is looking at the long term outcomes of bariatric surgery for type IIs as far as their diabetes is concerned. I'm assuming that it's not a lot of good for type IIs who are not also overweight. I think I read somewhere that Bypass Surgery was better than the gastric band. Google digs up costs of Gastric Bands as being between £5k and £8k, Gastric Balloon between £2k and £5k and Gastric Bypass between £9.5K and £15K. Return to work after just 7 days.
I think Professor Roy Taylor's research at Newcastle University is also interesting, further info available at
http://www.ncl.ac.uk/magres/research/diabetes/reversal/#overview. Looking at the cost and possible dangers (although slight) of Bariatric surgery maybe the Newcastle diet is a simpler method of achieving the same result. I believe that is what Professor Taylor was setting out to do anyway. If sticking to such a draconian regime is not possible, how about "hospitalizing" patients for the 2 months required for the Newcastle Diet. Not much good if you're working but cost wise comparable.
What I like about the draconian 600 - 800 calories a day is the ability to eat a meal rather than something the size of an egg.
