hey kasper
like kim said, try researching experts in your area.
but i agree, if your doc doesnt know what to do with you then its time to seek other opinions.
my weight was crashing too--83 lb at 5'4"--also dealing with the diarrhea and everything. i just had an ileostomy done on april 7th and have already come up to 95 lb. sounds a little drastic, maybe. but my situation was drastic.
despite othe complications, it has slowly been turning the overall health of my body in the right direction.
find a doc who will find solutions for you!
