I am 25 years old. For years I have suffered with extreme fatigue I was tested for iron deficiency anaemia which was negative so just put it down to life being tiring and working shifts. Last year I started to suffer with stomach problems - severe bloating, pain, urgent loose bowel movements etc. At the same time my dentist said my teeth were very eroded and suggested I get checked for Coeliac. Blood tests were negative but did find a Vitamin B12 deficiency and because of my symptoms I had a stool test, gastroscopy and colonoscopy as well as more blood tests. They ruled out Coeliac and any serious bowel disease saying it was just IBS. They also said I didn't have Pernicious Anaemia because the intrinsic factor blood tests were fine. So now I'm left having 3 monthly B12 injections and still experiencing some stomach problems that don't appear to be linked to food. I have no idea why and the doctors aren't investigating they just seem happy with given me the injections every 3 months.
Has anybody experienced anything similar or have any advice for what I should be doing?
