Hi there my names lisa, my gastro specialist today has told me that he is suspecting that i have crohns disease but i am still waiting for the diagnosis (swalling the pill camera next week) but what i would really like to know is if anyone else has experinced weight gain instead of loss with crohns prior to been on medication and also some constipation. i have had a look into forums and things and am finding it hard to work out if anyone has experinced this with out been on medications. currently i have gained about 20kg in the space of about 1-2 months. also can stress trigger an attack?
