I'm the oddball, I have crohns (crohns-colitis specifically) my CD is affecting my colon and I quit smoking for 3 yrs and it my CD really went hellish on me, I started again and it relieved it some...I also take natural products, mostly natural anti-inflammatories and eat a healthy diet, nothing processed at all...I drink only water and chamomile tea and exercise regularly...with all the changes I've made (including starting smoking again) I went from going 30+ times a day down to 5 or less on average/day.
I'm NOT encouraging anyone to smoke because research does say it's one known trigger for crohns (IBD in general) and although it can be helpful for UCers (not all benefit from it) and detrimental for CD, nothing is written in stone...they say that CDers that smoke have a great increased risk of disease activity particularly in the small intestines which I havn't had since the first yr I got sick with CD (17 yrs ago now).
I take the following;
fibre supplements (as directed by my GI)
vitamins B12, A, C-calcium ascorbate
oil of oregano
Everyone is different, what works for some doesn't work for all, it's important to try only one new thing at a time so you know what is helping and with what...typically it's a combination of things that can bring on improvements compared to just one thing...each thing should be given a fair chance, it can take time for things to kick in before you start to notice improvements.
I am not on ANY oral RX for my CD as I'm either allergic or non-responsive...I have IBS as well.
My bum is broken....there's a big crack down the middle of it! LOL :)
