wolverine2,
I think that with both UC and Crohns it's somewhat typical to lose weight.
And the other problem is of course: malnourishment and malabsorption of foods, vitamins, etc...
That's the reason it's so important to supplement.
I've lost 30 pounds within 6 months of being diagnosed with UC.
Yea, UC sucks big time!
You have to find ways of boosting your nutrition. Have you given any thought to adding a good quality protein whey?
