I quit alcohol completely in 1998 and have not had a drink since. I was a pack a day+ smoker until I quit in June of 2009. Never had any stomach or digestive problems in my life. Took up walking and some running to replace the smoking and clocked about one hour per day of exercise. Was running quite a lot the month before I got sick and walked in a local 5K, no problem. Was also eating lots of salads and fruit and fiber. Had some extra stress in my life due to a promotion at work and the illness and death of a very good friend. Otherwise life was ok. Then all of a sudden in July 2010, I thought I had a stomach bug and when as it got worse, food poisoning. Got progressively worse with the bleeding when I went to the bathroom and I ended up spending a week in the hospital, diagnosed with UC or Crohns Disease and treated with lot of IV Levaquin and Prednisone. Went on a low residue diet and did everything my doctor told me. Stayed on the Prednisone until I weaned off of it in January of this year and I am currently on Lialda and Nexium and have not had a flare up since last July Thank God. Tests have been inconclusive as to whether I have Crohns or UC and I am due to go for a follow up colonoscopy in July to see how it looks. I am a 48 year old male and I am always speculating as to what might have triggered this in my life. I've also had a mild case of psoriasis since I was 14 years old which is always with me to one degree or another despite lightbox treatments for the past for the past year and a half. Oh, by the way the psoriasis disappeared completely for six months while I was on the Prednisone (magic!) but is back now that I'm off it. There is not history of UC or Crohns in my family and I always thought that I had the constitution of a horse. Do what's your theory on why I got this Inflammatory Bowel Disease? What do you think could have triggered it? Any feedback would be much appreciated. Thank you all.
