I CAN NOT BELIEVE THE AMOUNT OF IGNORANCE I SEE ON THIS WEBSITE ABOUT GASTRIC BYPASS! Even from those who've already had it! Do your doctors teach you NOTHING? I'm SO glad I have a doctor that educated me about EVERYTHING ahead of time.
A) you have pain on your left side because that's where they used the instruments, and they manipulate them pretty roughly during the procedure.
B) you get sick and vomit because you're eating the wrong things, or eating too soon after surgery! High fat and high sugar foods will cause what is called "dumping syndrome"
C) There are FIVE stages of re-introducing food to your diet. The first being clear fluids while in the hospital, second is protein shakes, milk, jello, thinned down puddings and yogurts, third is soft and pureed foods such as scrambled eggs, yogurt, cottage cheese, mashed potatoes, squash, pureed meats, etc. Fourth introduces finely chopped meats, fish peeled potatoes, crackers, well done toast, canned fruits in light syrup, lean ground meats, beans, etc. Fifth stage introduces everything else, but warns that some foods can still cause some irritation such as high fat gravies, bbq sauces, etc.
D) the limit on the grams of sugar allowed is FIVE! If your food or candy has more than FIVE grams of sugar per serving, then it's a safe bet that you will vomit, get diarrhea, cramping, sweating, etc. It's called DUMPING SYNDROME.
I'm pretty sure there are OTHER issues out there I haven't read yet, but for crap sakes get educated about your body and what you just had done to it...you're not going to be successful at your weight loss if you don't start learning about your body and the things you put into it!
