Poop Question

25, female, 4’11, 180 lbs

IBS-NOS, CSID, possibly celiacs, OCD

citalopram, famotidine, probiotic, bc, xyzal

for the last 7 years, i have been strictly gluten free. i was having super bad stomach issues (diarrhea and rapid weight loss) and when i went to a pediatric GI doctor, i had a colonoscopy and that came back fine. she told me to stop eating gluten so i did. then told me based on the colonoscopy that i had CSID and IBS-NOS.

fast forward to more recently. i’ve been questioning whether or not i really needed to be gluten free. so i’ve been eating gluten and things seemed to have been going fine.

for the last few days i have had normal bowel movements, but they have been green. i have not eaten anything green or blue dyed and no leafy green veggies or even green veggies at all. tonight i had watery green diarrhea. this green is literally like the color of fresh broccoli.

i don’t think i can be sick because i haven’t left the house in a few weeks, and no one in my family is sick either

i drink 100% grape juice everyday but i have been doing this for at least 3 years, it is not something new that i have recently added to my diet. it’s been there for a long time.

i guess i am just wondering if this is something that i should be concerned about or if this could possibly be from having celiacs disease?

thank you
