Its perfectly natural to have lots of questions buzzing around in your head and to start looking for answers. The better informed you are the better your outcomes will be for you. As many have said try not to dwell too much on the extremely negative stuff reported in the media, as these are the minority and far outweighed by the positive stories.
I have 5 good friends who have had gastric bypasses, none of whom had any traumatic experiences and have all had fab results from their ops.
With regards to addiction transfer, i was aware from my research that this happens to some people, but again i don't know any that have developed any dangerous ones. Mine is that i can't stop baking/cooking ! When i get bored i find that my hands get restless (because in the old days they would be stuffing food in my gob lol) so i go and bake, and then pass stuff on to friends, family and colleagues - i've become a feeder !
I'm not great at sticking to the best of diets, but still all my blood tests come back fine, no malnutrition issues.
I did experience hair loss, and my hair went a bit thin, but this was only temporary and is back to normal now.
As for kids, my consultant advised me not to get pregnant for two years post surgery, but that it would be okay after that.
I lost weight easily and quickly for the first six months and then hit a plateau. Old bad habits snuck back in, and although my pouch is still tiny and i can't pig out i found myself picking regularly at little bits. I didn't gain, but didn't lose either for nearly six months. However i've just lost four pounds, so things may be getting back on track.
I have no problems with any savoury food, nothing sticks or makes me ill, but i still can't tolerate much sugar (few squares of choc, two digestive biscuits - any more and i feel poorly)
In short, my bypass works if i work with it !
Before and after your op you will get the chance to speak to a surgeon and dietician and specialist nurse, so ask them all the questions you need to - they'll be used to it. My poor anaesthetist was exhausted when he left me the night before my op lol.
Some of the best advice i have received though was from other bypassers - the best source of knowledge is from those who have experienced all the highs and lows themselves. My friends that i met through this forum didn't sugar coat anything for me, so i was well prepared for how i would feel when i woke up and what to expect over the first few months.
Feel free to keep asking the questions and sharing your concerns, it may help to reduce any anxieties x x
