It seems everybody's recovery is different so its hard to give advice.
I had my ileostomy reversed 2 weeks ago, I spent a couple of days waiting for my bowels to start working, once I passed gas I was allowed clear fluids and then once I had my first bowel movement I was free to eat.
I was suprised that the surgeon did not mention anything about diet but I spoke to a nutritionist who suggested I start on a low fiber diet for at least 4 - 6 weeks.
I had been following that and going for walks daily but somehow developed an obstruction and am now back in the hospital.
I would reccomend being clear with the doctor abput pain medication expectations. Some pain killers can be highly addictive and cause constipation so its a fine line. You will definitel need something for when you are home but find out how long they expect you to need it and when you should/can start to taper off it.
If you are a crohnnie (like me!) then you are familiar with frequent bowel movements, just be prepared with the lotion and soft tissue!
Good luck and keep us posted!!
