Hi guys! I am new to this. Back in December I thought I had the stomach flu for about 2 weeks and was also going on vacation (jamaica). I still went on vacation thinking I was on the tail end of the bug. Ya not so much! I got worse and ended up in a Jamaican hospital for 24 hours. They told me I was dehydrated and had a bacaterial infection. Stayed in room till my trip was over and flew home. Got up the next am and felt no better. Was admitted to hospital and ran all kinds of tests to discover I had Crohn's disease. I was prescribed prednisone and cutting dose every week. I start Humira tomorrow. I was told this will make me very tired. I am also concerned about weight gain. I have been on prednisone and was told the same thing. I have been walking every day 2 miles a day, watching my diet (2000 calories a day) and also using the eliptical everyday. I have not gained anything but not lost anything (feeling discouraged). Has anyone had issues with weight gain on Humira???? I go back to the doctors on april 9th for a follow up. My question I am really to find out about is what exactly is a flare-up? Reason being before this incident I had always had pretty much loose stool and would use the bathroom sometimes right after a meal (sometimes not). I just want to know what i should be looking out for. I know I am totally all over the place with this, sorry! Just so many questions and felt as though I never got any answers (especially why now I have Crohn's at age 43!). Thanks for reading!!!!!!!!
