It will take at least a year for your bowels to fully optimise itself to your new plumbing, perhaps even longer. The bowels aren't a set of inert tubes, but constantly contracting and pulsating and working in tandem with different parts of the bowel via nerve signals to push food along (a bit like how an earthworm wriggles along the ground). It's all automatic and normally you, or your bowels, never think about
it. But when something disrupts the process - like bowel surgery - then your bowels have to re-learn how to push food/stool from one section to the next without getting into a tizzy.
You won't have the same symptoms for all that time though; after a few months things should be dramatically better, if not 100% back to normal. If they aren't, then something's not right and you should go back to your doctors.
I did have a similar experience after my surgery, but the Crohn's coming back complicated my recovery, so I still have problems 2 years later. I'm still not going as many times a day as I was in the first few months after surgery, however.
Dx Crohn's in June 2000. (Yay )
Tried: 5-ASAs, azathioprine, 6MP, Remicade, methotrexate, Humira, diets.
1st surgery 20/2/13 - subtotal colectomy with end ileostomy.
2nd surgery 10/7/15 - ileorectal anastomosis. Stoma reversed and ileum connected to the rectum.
Current status: Chronic flare. Do I have any other kind?
Current meds: 50mg 6MP; Entyvio (started 3/11/16)
