Karl Tucker, 25, of Westminster Way, was diagnosed with the incurable condition in May 2014.
Crohn’s disease is a condition which causes inflammation of the digestive system or gut.
Mr Tucker will have to wear a colostomy bag for life after undergoing a series of operations.
The disease had left Mr Tucker severely fatigued with difficulty walking and needing help from his family as well as needing to visit the toilet up to 12 times a day.
He has tried several different medications and was admitted to hospital several times between August 2014 and March 2015.
Mr Tucker, who is a team leader at Swalcliffe Park School, has undergone a number of operations – including one a week after his wedding.
Mr Tucker said: “I’ve got to have my large bowel removed. It’s been a year of massive ups and downs. I got married last July but from April 2015 to August, I had to have three operations. It has been a real up and down road, but I’ve still got to have this operation. The reaction I’ve had from people has been great.”
Mr Tucker’s weight went from 13st 6lbs to 11st 6lbs. In December, Mr Tucker started exercising again in a bid to improve his health by cycling.
He said: “I started to train properly in January and to date have really started to change my body shape and this is thanks to the LDN muscle cutting guide.
“Life with my stoma is different but manageable but not without its problems. I sometimes get leaks and my skin can get sore as a result.
“I’ve just changed to a new bag which is preventing leaks and improving my confidence with my bag.”
