i am currently 25 years old. i have been having problems relating to the digestive system for about 4 years now. there have been bumps here and there, but it has always been a day to day concern of what was going to happen. at the begining of 2010, most everything i ate started to bother me, forcing me to stick with only 1 or 2 things i could eat, which still caused discomfort for several straight months. after one colonoscopy/endoscopy, lower bowel series, ultrasound, and alot of blood work, one GI tried to pass it off as being IBS, so needless to say, i fired him.....after a short time, i found another GI, he immediately suggested a biliary scan (test gall-bladder function using nuclear medicine) so i did, and it came back with only 17% operation, so in August of 2010, the GB came out. a few months past feeling much better and actually gaining some weight back, but then it all came back again. i can now eat better than before, and am holding a stable weight, but i constantly get lower and upper abdominal pain. i have since then had another colonoscopy/endoscopy, as well as a capsule test. dr. told me i had trace amounts of parasites, and prescribed me antibiotics for it. i have been off of the antibiotics for a few months now. i was also told that my vitamin D was very low, so i was also prescribed 50,000iu of vitamin D once a week for 4 weeks and am now taking One A Day Men's to keep vitamin D in me. i still as bad if not worse than i did and i can't go on like this anymore on a day to day basis. can anybody out there please give me an answer?
