I found myself hungry but nauseaus at the same time through much of the first year and a half of symptoms. I ate a lot of carbs, craving cakes and whatnot before I cut out wheat, and then potatoes, rice, etc. I think this was because of the fat malabsorption. I had a fairly high score on the fecal fat test, as well, and given that my body was not absorbing...
When i first started having symptoms, i had this problem. Stools were loose, mucously, fatty, full of undigested food, and I always felt very feverish and uncomfortable passing them....would sit on the toilet for long periods, not constipated, but clammy and in pain.....
