Happy birthday and may God bless you today!
I am also having problems gaining weight. I am currently 22 and have been diagnosed with celiac disease since I was a few months old. I have always been thin/lean as I spent most of my school days playing sport. However as I have got older I hevent gained much weight at all depite the fact that I eat like a horse. About 3 years ago I was also diagnosed with ulcerative colitis which was a bit of a shock - I was extremely ill for over a year and am currently taking asacol tablets to keep the condition under control. I was also on steroids for a while to counter-act the negative effects of the laxatives etc I had to take (I have had 3 colonoscopies since I was diagnosed). As bizarre as it may seem however, I still didnt gain any significant weight when taking steroids, I just found I was eating more often. I wouldn't say I was severely under weight, Im just a little puzzled at how I can eat so much and yet my weight doesn't seem to change. Sometimes the effects are noticable (looking in the mirror etc), other times its simple things like my watch almost falling off my wrist as the amount of flesh on the bone has decreased. I'd like to do something to gain weight, even if only a few pounds. I have read the replies above and may try some of the food changes proposed, any other advice would be greatly appreciated. Would someone such as my GP be able to offer any advice?
