hi i have been nauseated for 7 months and lost about 70 pounds could it be from the cotazym as i,ve had a lot of tests done and they all come back normal.the gastrologist put the scope down to check my stomache and small intestine twice and that was normal then she put the scope up my bottom to check the large intestine and that was normal and i had a barrium swallow that came back normal i,m at wits end
