In 1989,I was almost 300lbs & had a gastric bypass.For the past 2yrs.,I've had lab results with extremely low Vit. D,Vit. B12 & elevated liver enzymes. I have severe bloating & back pain after eating,severe joint pain as well as Osteoporosis. I have ALWAYS led a very busy,PHYSICALLY ACTIVE lifestyle...NEVER BEEN A LAZY PERSON!I'm so depressed & frustrated because of not being able to enjoy ANY of my outdoor hobbies,or play my guitar(stiff,sore fingers) & weight gain.Some days I wonder what's my purpose for even existing anymore...NOT TRYING to sound mellow-dramatic,just being honest. Has ANYONE OUT THERE endured these post surgical issues YEARS AFTER a gastric bypass?ANY DRS OUT THERE have any suggestions on what kind of Dr I should see to be PROPERLY EVALUATED & what kind of treatment I should expect?? THANKS IN ADVANCE FOR ALL REPLIES!!
