i recently had cervical disc surgery on c5 thru c7. since the surgery, I am gaining weight due to strange hunger cravings that i didn t have before. I had my thyroid checked a few years ago and it was ok and have had the lap band surgery a couple years ago. so I am not sure what may be causing this and there is no chance i am pregnant either. I am 45 years old and am not on any medications other than a multi vitamin, calcium supliments. a friend of mine seems to think itmay be thyoid related. could my surgery of the neck cause thyroid issues. this is the second surgery done on it in a year. if it makes a difference they went through the front of my neck to do both surgeries. I don t know what else could cause me to put on weight so fast. Lisa
