Sorry if there is already a thread on this but I couldn't find one.
I was diagnosed in Feb after sudden and significant weight loss (3st), constant toilet trips, loss of appetite and lots of pain. After a scope found ulcers in lots of different patches of my large intestines, I was diagnosed as having Crohns.
I was given IV steroids then onto prednisolone reducing each week from 8 tablets to none. I was also put on Pentasa as my liver function wasn't great so they decided against azathiaprine.
I've since had an MRI which confirmed there were other areas further up that were affected too -hence the pain.
The steroids did the trick and I was symptom free. However, I piled back on all the weight Iost, was moody and sprouting hair in places that had never had hair before.
After a couple of weeks off the steroids, the symptoms started creeping back. The pain and toilet trips. Not any weight loss unfortunately as I'm as big as ever. 
The doctor has put me back on 8 steroids, reducing again. I am certain I will put on tonnes of weight. I know that my health is more important than my appearance but considering I've put on 2st in about 2 months I'm slightly concerned I will put on another couple of stone and will be as wide as I am tall.
I just want to get back to normal and I'm very sad I'm not the mum I used to be to my little girls because I have no energy.
Tell me it will be better soon.
