I was hospitalized 5 times while I had UC. Those stays we're usually around a week for bowel rest, IV steroids and blood transfusions.
For my surgery step one was 10 days (which felt like an eternity) and step two (takedown) was 4 days. A week after I got home from step one I developed and abscess and had to go back and that ended up being another week in the hopsital. So the 10 days was the longest consecutive days I ever had to stay in the hospital.
God bless any of you that had "weeks" in the hospital. I go bonkers after few days there!
