Hi i have a question about some labs that have come back recently. Last year i had a lot of digestive issues (bloody diarrhea), docs thought it was crohns, but it came back as IBS. Been recieving b12 shots for a year now every three months. just went for a yearly physical, and my doctor is unhappy that my b12 is still so low. my vitamin d is also low now. could this all be due to IBS? or is this turning into crohns? my folate is normal, just my b12 and d are low. so now im going for the shots every two months plus oral dissolving pills plus vitamin d caplets. is this just a malabsorption issue and if so, what is causing this? i was tested for everything last year-celiacs, hpylori, pernicious anemia, crohns, colitis, etc. thank you!
