I had a question. It seems like my symptoms came on a week from each other; does that mean my cause is acute? sub-acute? or chronic? I know it's impossible to know, but what do you guys think? Also, I'm going in for a colonoscopy to get my gut tested in regards to my diarrhea... I had a question for Rose or for anyone. I noticed that in your webpage about B12, it said that parasites or bacteria would cause a malabsorption of b12. Do you think my colonoscopy would be able to catch those things? I think it would be good to know so I can ask my doctor about it. Anyways, if you don't know, it's not a problem; I can ask anyways. Thanks!
