Hi Mazrob - firstly do not panic - your sleeve has not failed, I absolutely promise you. Firstly I must emphasise that I am not medically trained in any way and in no position to advise anyone. Please DO NOT COPY ME.
I was a band to sleeve conversion on 12th November and by one week out was very hungry indeed. I decided, (without medical permission) to experiment with some porridge (the next stage up) and was devastated to discover that I could eat a vast (600ml) amount. DO NOT COPY ME. With no discomfort whatsoever. As if I had no sleeve. I concluded that the sleeve had failed in some radical way, just as the banding had. Devastating.
The next day I hit the phone to my medical team. Both surgeon and dietician have said that I have healed alarmingly quickly and must have virtually no internal swelling left. The porridge had emptied out of the sleeve very quickly. For some reason they both said that this may have been caused by having a resilient stomach due to the banding - all these fills and defills. Anyway, the decision was to to move me forward to an evenly textured soft diet. Yes at one week out! This has worked perfectly and my new sleeve has the capacity of one scrambled egg. This has completely taken the problem away. Believe me I know that I have a completely working sleeve now and feel stuffed on that amount. To do this off your own bat could be extremely dangerous ie it could cause a leak in your staple line. Extremely nasty and potentially life threatening.
You have two options. Consult again with your surgeon to seek permission to move early to the next stage of eating. If you get it proceed with HUGE care. If not, just endure being hungry for a few weeks more following the usual progression. Then you'll relax knowing that your sleeve is fully working.
Another thing that the surgeon mentioned is that when doing a conversion the stomach has to be stretched and pulled back into a normal shape. This apparently can temporarily mess with stretch receptors and cause a sort of "fake" hunger which fixes itself over a few weeks.
We are conversions and the failure of the previous bariatric surgery has had a negative psychological effect. There is no device implanted which can fail, this time. Your sleeve has not failed. You are healing more quickly than most, is all. Good luck with your weight loss and take care.
