I have been admitted numerous times over the last 5 yrs. Atleast 3-4 x a yr.
My GI bases it on my symptoms. Usually it is due to BM's more than 15 x a day w/ mass amounts of blood, vomiting, pain.
I am treated w/ IV steroids, antibiotics, and pain meds.
It sux being admitted, and i would WAY rather be treated at home, but sometimes, i just get past the point of being able to function.
Good luck and hopefully u won't need to be admitted.
