Started to have gastric problems (think it was the start of a hiatus hernia) after piling on the weight, decided enough was enough and lost almost twenty pounds, problem gone.
My brother in law had an op to stop gastric reflux (he had it bad), its the one that somebody else described were you can't vomit even if you want to.
He was overweight at the time and the docs had to open up the chest cavity through the ribs to get at it.
When he come round he was in agony, he was getting v. high doses of morphine but was still in agony for the best part of a week (at one point he wanted to jump out the window of the hospital to kill himself, thats how bad the pain was). He was later told that he could have slimmed down it could have been done by keyhole (was he p*ssed off or what). To compound matters they ended up infecting the wound with MRSA which destroyed a lot of tissue around the scar (has to wear a corset thing to keep things were they should be).
I guess the moral of the story is if you have to get an op like this, make sure you slim down first!!!!!!!
