I got diagnosed about 5-6 years ago now, it took about 6 months to get a correct diagnosis. I first went to the doctors because of the extreme tiredness I was suffering from, this ended up being because I was suffering from Anemia, which was caused from the Crohns.
Throughout the 5-6 years i have had a number of Colonoscopies, Sigmoidoscopies and Endoscopies, and i regularly have check ups. I have been on a number of different drugs, the best being Infliximab, which I was given through a drip once every 6 weeks - it worked a treat clearing up the fistula's I had, now i am on some drug called Methotrexate (or something like that)
Diet wise for me its kind of what is bad for most people is good for me. So I stick to white bread instead of wholemeal, likewise with pasta . Steer clear of fruit and veg unless its skinless and has no bits. And steer clear of caffeine and alcohol. Now I have to say i am pretty rubbish at following this as i like all kinds of food, flippin love coffee and have a tendency to have one to many pints! So I tend to take each day as it comes with what i eat and drink, if i am having a bad day i will be good, thankfully i have had more good days lately
