I didn't look at tht link but when I was researching anorexia and deficiencies,damage so on I came across a link of gall bladder issues. So may be try anorexia and gall bladder. If I recall it talked about how the body empties slowly and hard to digest fats so on. It may also have similar issue to the gastric bypass Roxie would know more about that cause that has similar complication sometimes to anorexia.
