Please look into two things for your crohn's disease:

1) low dose naltrexone - put 2/3 of crohn's patients into remission in 12 weeks in one study. Experimental use of an old medication, very tiny dose , very inexpensive and easy to take. Go to lowdosenaltrexone dot org for more info.

2) A grain-free Paleo diet once you get back on food. Completely gluten-free. Check out marksdailyapple dot com website for more info.

Also, get your B12 and vitamin D levels checked.
